Mark Wegner Promoted to Crew Chief for 2018

Mark Wegner is now a permanent MLB crew chief, filling the vacancy left by the retirement of veteran umpire Dale Scott. His promotion and new supervisory status was quietly included alongside the 2018 Spring Training umpires' roster.

Mark Wegner is MLB's Newest Crew Chief.
With 20 years of Major League experience since his 1998 National League debut, Wegner has served as an interim crew chief on several occasions, and most recently served in the backup role ("Umpire 2") on Mike Winters' "M Crew" (the "M" stands for Mike Winters, Mark Wegner, Marty Foster, and Mike Muchlinski).

For Winters' "M crew" to persist in Wegner's absence, baseball will need to assign as a replacement Mark Carlson or Marvin Hudson (both presently Umpire 2s on other crews), or Ump3/4s Mike DiMuro, Mike Estabrook, Manny Gonzalez, or Mark Ripperger.

Wegner most recently officiated behind home plate during Game 7 of the 2017 World Series (his sixth straight postseason since suffering a torn calf muscle injury in 2011), and won the UEFL's Best Umpire of the Year Award in November.

Wegner will leave behind the fabled "M Crew."
In January, we discussed the potential candidates for baseball's only opening for the leadership position ahead of the 2018 regular season, identifying Angel Hernandez, Jim Reynolds, Alfonso Marquez, Mark Wegner, and Ron Kulpa as the top five candidates based on statistics alone.
Related Post: Running the Numbers for MLB's Next Crew Chief (1/12/18).

Wegner comes into the role as the statistical fourth-most qualified, behind Hernandez, Reynolds, and Marquez.

Wegner first assumed a regular "Umpire 2" (backup crew chief) role in 2013, as did Marquez; Kulpa became an Ump2 in 2012, Reynolds in 2010, and Hernandez in 2002. Wegner's 12 postseasons are fifth-most amongst eligibles (Hernandez [16]; Eric Cooper, Greg Gibson, Kulpa [13]), and his Review Affirmation Percentage (RAP) since 2014 ranks 12th best in the league, behind only one other candidate (Marquez, 3rd).

The statistically most-qualified Umpire 2, Hernandez, sued MLB's Officer of the Commissioner in 2017, alleging, amongst others, racially-motivated discrimination in baseball's failure to promote him to Crew Chief, while promoting less qualified white umpires instead.

2018 MLB Spring Training Umpire Roster

Announcing the first sign of baseball season, it's the 2018 Spring Training Umpire roster. Comprised of 91 umpires, including 76 full-time MLB + 15 minor league call-ups and invitees, this preseason's officiating list for Arizona's Cactus and Florida's Grapefruit Leagues contains 11 less umpires than the 2017 Spring Training list (102 umpires). This decrease is due in large part to the absence of a World Baseball Classic tournament this spring; the 2016 Spring Training roster, a year which similarly did feature a World Baseball Classic, consisted of 95 umpires.

The following roster includes sleeve numbers for all applicable umpires; Minor League Baseball umpires with numbers are deemed Call-Ups and may fill in during the regular season at the Major League level, while MiLB umpires without numbers are the Spring Training invitees and are not yet on MLB's fill-in list. The MiLB umpire in bold is new to the Spring Training list.

ABL Ejections - Takahito Matsuda & Bench Clearing

Sunday's decisive Australian Baseball League Championship Series Game 3 featured a bench-clearing incident and two ejections by 2B Umpire Takahito Matsuda en route to a Brisbane Bandits 4-2 victory and ABL win over the Canberra Cavalry.

First, the bench clearer. With two out and none on in the bottom of the 6th inning, Bandits batter Andrew Campbell took a 2-2 fastball from Cavalry pitcher Frank Gailey inside for a hit by pitch, resulting in a bench clearing incident. Replays indicate the pitch hit Campbell in the upper back, the call was irrecusable, resulting in warnings from HP Umpire Mal Mackay and an extended conversation with both managers; relief pitcher Steven Kent replaced Gailey following the at-bat. At the time of the incident, the Bandits were leading, 4-0.

One pitch later, 2B Umpire Matsuda ejected Bandits 1B Coach Adrian Lamb for fighting during a second bench-clearing event that started after Bandits baserunner Campbell was caught stealing at second base, and Manager Dave Nilsson for arguing the incident. The Bandits ultimately won the contest, and the Championship Series, 4-2.

Analysis - Tennessee Wins on Walk-Off Obstruction Call

The Tennessee Lady Vols won a weekend softball game against Utah after an umpire's obstruction call on a game-ending play at the plate scored the winning run. Was the call correct pursuant to NCAA rules or should the game have continued?

Utes catcher Martinez blocks plate too early.
The Play: With the bases loaded in the bottom of the 7th inning and Utah leading, 5-3, Tennessee batter Abby Lockman hit a 2-1 pitch from Utah pitcher Miranda Viramontes to left field, scoring baserunners Chelsea Seggern and Scarlet McSwain. Utah left fielder Julia Noskin retrieved and threw the ball to catcher Kelly Martinez, who received the throw as R1 Brooke Langston arrived at home plate, resulting in a game-ending obstruction call from HP Umpire Vince Price, who signaled a delayed dead ball as soon as the violation occurred.
Video at bottom of post.

Still image of catcher's tag of baserunner.
Analysis: Replays indicate that Utah catcher Martinez caught the ball and tagged baserunner Langston before the latter touched home plate, but also suggest that Martinez positioned herself in front of home plate and between the plate and baserunner Langston before gaining possession of the ball. Key to the analysis is a college softball rules change, enacted just in time for the 2018 season.

The Rule: Pursuant to the NCAA Softball Rules Committee's recommendation over the winter, the sport's new Rule 9.5.1, regarding obstruction, states:
Obstruction occurs when a defensive player, not in possession of the ball or in the act of fielding a batted ball, impedes a batter's attempt to make contact with a pitch or impedes the progress of any runner who is legally running bases on a live ball. It can be intentional or unintentional. It is obstruction if a defensive player is blocking the whole base/plate or base path without the ball and/or the runner does not have a clear path to the base/plate. (See also Rule 12.13.)
Rationale: College softball's move toward eliminating the defense's opportunity to block the plate without the ball follows both NCAA and MLB baseball's move to eliminate this area of potential contact. For instance, both baseball and softball agree that once in possession of the ball, the catcher may be positioned between the runner and plate, and all rules codes allow for the runner to be called out if, not withstanding the catcher's positioning, she would have been out by a throw that clearly beat her. College softball's obstruction rule formerly referred to a catcher in the act of fielding a throw (baseball still allows this); softball's present rule requires possession first, in a "Catch=>Block=>Tag" sequence of legality, thus rendering "Block=>Catch=>Tag" explicitly illegal.

An example of a legally positioned catcher.
Baseball Equivalent: OBR's Rule 7.13 came into existence ahead of the 2014 season, and outlawed certain collisions at home plate by prohibiting the catcher without possession of the ball from blocking the pathway of the runner while prohibiting the runner from deviating from his path to initiate contact with the catcher.
Related PostTest Yourself: MLB Adopts Home Plate Collision Rule 7.13 (2/25/14).

The rule also allows a catcher to move up the line to catch a thrown ball, even if such a catch would take the catcher into the runner's path, and dictates that a runner shall be called out if he would have been out "notwistanding the catcher's improper positioning in front of the plate."
Related PostMLB Issues Rule 7.13 Plate Blocking Clarification (9/10/14).

After the catch, F2 legally blocks home.
SIDEBAR: One notable difference between the codes is that, in softball, this form of obstruction can occur on a force play. In MLB baseball, however, force plays are excluded from the plate blocking rule (MLB added this exclusion in June 2014 after a force play was called off due to the catcher's blocking of home plate; the formal language went into effect for the 2015 season under 6.01(i)(2)).
Related PostHow to Illegally Block the Plate with the Bases Loaded (6/4/15).

Still, this rule (now known in OBR as 6.01(i)(2)) has caused its fair share of controversy in baseball, most recently resulting in Cubs Manager Joe Maddon's ejection from Game 1 of the 2017 National League Championship Series for arguing a Replay Review decision that overturned an out call to that of a Rule 6.01(i)(2) violation, thus scoring a Dodgers run.
Related PostMLB Ejection P-2 - Mike Winters (2; Joe Maddon) (10/14/17).

An example of an illegal catcher.
As was the case during the 7th inning of Utah-Tennessee softball, Cubs catcher Willson Contreras had positioned himself in front of home plate—and, specifically, between the plate and scoring baserunner Charlie Culberson—such that even though the throw was up the line, and Contreras may have legally moved into the runner's path in order to field the throw, he nonetheless violated MLB's plate blocking rule simply because he started the play positioned illegally between the runner and the plate.

Conclusion: As such, HP Umpire Price's obstruction call to end the Utah-Tennessee softball game was correct; Utah's catcher started the play in an illegal position between the scoring runner and home plate, thus forcing the runner to alter her path toward home even before the throw arrived in the vicinity of the plate.

In other words, the NCAA wants the play-at-the-plate sequence to read "Catch=>Block=>Tag." By changing the sequence to "Block=>Catch=>Tag," Utah committed obstruction in contravention of Rule 9.5.1, and awarding Tennessee the game-winning run was indeed the proper call.

Close Call Sports & Umpire Ejection Fantasy League is getting a facelift. Over the next week, the website's appearance will be fine tuned in preparation for the upcoming 2018 UEFL season. We'll be open during construction, meaning you will still have access to all CCS content, and we'll continue posting news stories and other content as per the usual offseason schedule. The site may look odd or downright broken over the next few days, but rest assured, we'll be busy working on a new look.

What's more, you will now be able to visit Close Call Sports over an encrypted, or secure, connection. Similar to the circa-2017 address at, the encrypted link will be accessible at (adds an 's'). Both links will work for the time being, but our goal is to redirect all traffic to the secure connection at some point in the future.

Will Little Inducted into Science Hill Athletics Hall of Fame

MLB Umpire Will Little has been inducted into his alma mater's Hall of Fame, accepting his plaque this month from Science Hill's athletics department. He goes into the high school's Hall as both a baseball and basketball alum.

MLB Umpire Will Little is a HS Hall of Famer.
During Little's senior year at the Tennessee high school in 2001-02, Science Hill basketball finished as state runners-up and the baseball team won conference, district, and regional titles.

Little continued playing baseball while attending Milligan College (studying biology), after which he attended the Jim Evans Academy of Professional Umpiring in 2007, landing a job in the Gulf Coast League shortly thereafter before his 2013 MLB debut and 2015 full-time hiring.

The Science Hill Athletics Hall of Fame biographies are available via the Johnson City Press.

GHSA Affirms Basketball Protest, Orders Replay

Having already entertained protests in two sports (baseball - affirmed; football - denied), the Georgia High School Association brought its Board full circle, hearing a protest in its third-straight season as the GHSA overturned a basketball game result based on a misapplication of the rules.

Related PostDangerous Precedent - GHSA Overturns Judgment Call (5/22/17 - Baseball Decision).
Related PostGHSA Amends Bylaws to Exclude Judgment Calls (12/20/17 - Football Decision).

GHSA has heard 3 protests in last 3 seasons.
Unlike the baseball and football plays, however, the most recent basketball case features a protest based on a rule interpretation issue, as opposed to a judgment call.

With nary one second remaining in the fourth quarter and Discovery High School leading Collins Hill 45-44, Collins Hill prepared to throw the ball in along the far end-line. After a throw-in violation, Discovery received a throw-in at the spot, upon which an inbounds Discovery player punched the throw-in pass toward the goal, and away from opposing Collins Hill players, prompting a whistle (it is illegal to punch or strike the ball with a fist).

After a conference, officials ruled a technical foul against Discovery, awarded Collins Hill two free throws (which they made), and the game concluded thereafter with Collins Hill winning, 46-45.

NFHS Rule 9-4 prohibits a player from striking the ball with a fist, and its penalty states, "The ball is dead when the violation occurs and is awarded to the opponents for a throw-in from the designated out-of-bounds spot nearest the violation."

In affirming Discovery's appeal, the GHSA determined Rule 9-4 had been misapplied and ordered the game replayed from the point of protest (with Discovery leading 45-44):
Since this was NOT a ‘judgment call’ but a clear misapplication of a rule, play shall be resumed at the point of interruption when the violation occurred. It will be the responsibility of the two schools to determine when/where the resumption of play will take place and communicate that information with the local officials association and myself. Additionally, there shall be no added expense for officials assigned to finish the game in question.
NFHS Basketball does not recognize protests.
GHSA's decision to replay the Discovery-Collins Hill game angered Peach County, the football team whose December protest was turned down. Though GHSA officials made clear that January's basketball protest concerned a misapplication of rules and December's football controversy dealt with a judgment call, Peach County superintendent Dr. Daryl Fineran wasn't buying it: "This [Discovery] is a Gwinnett County school, and Gwinnett County wags the tail. It's the money, the socioeconomics...I told them that's ridiculous."

Added GHSA executive director Robin Hines, "We had the opportunity to make that right and correct that misapplication of the rules. That’s well within the NFHS (national federation) rules."

Except it isn't. NFHS Basketball Rule 5-4-2 states, "The NFHS Basketball Rules Committee does not recognize protests."

Players Reject Pace of Play Proposal, Override Probable

Although the Major League Baseball Players Association rejected his latest pace-of-play proposal, MLB Commissioner Rob Manfred may nonetheless overrule the MLBPA and introduce pitch clock rules for the 2018 season without the union's support, thanks to a CBA rule that allows the Commissioner to play hardball.

MLB may receive new pitch clock rules.
According to the Collective Bargaining Agreement between MLB owners and the MLBPA, the Clubs (which are led by Commissioner Manfred) are empowered to implement rules changes in one of two ways: A) With the players' consent, or B) without it.

If an agreement is reached with MLBPA) The rules may be changed for the upcoming season pursuant to the terms of that agreement; or,
If no agreement is reached with MLBPA) The rules may be changed without player consent as long as the Clubs wait one entire season before implementing the new, not-agreed-to rules.

Article XIII of the MLBPA's Basic Agreement states:
If the Clubs and the Association fail to reach agreement on a proposed change which is subject to negotiation, the proposed change shall not be put into effect until the completion of the next complete succeeding season (including the Wild Card Game, Division Series, League Championship Series and World Series) following the date the change was proposed.
Time is running out on limitless baseball.
In other words, this all goes back to the preceding offseason (2016-17), when the MLBPA rejected the Commissioner's proposed pace-of-play changes regarding pitch clocks and the like. Now that a full season and postseason has passed, the Commissioner has the authority to impose these same circa 2016-17 proposals, essentially overriding the players' veto.

To illustrate this principle, consider the Arizona Fall League, MLB's self-described testing ground for pace of play and other rules change initiatives. The 2014 AFL tested a concept called "no-pitch intentional walks," in which a batter would be awarded first base with no pitches thrown if the defense simply wanted to add a baserunner. The 2014 AFL also introduced a 20-second pitch clock.
Related PostMLB to Test Pace of Game Proposals at Arizona Fall League (10/1/14).

Though the 2015 and 2016 seasons retained the traditional intentional walk, Manfred's crew eliminated the practice ahead of the 2017 season, while decrying "a lack of cooperation from the MLBPA." Thus, the no-pitch intentional walk rules change was implemented in the majors over a year removed from its first appearance in the laboratory fall league.
Related PostFour-Pitch Intentional Walk, Potential Flubs, Abolished (2/22/17).

Manfred is authorized to overrule the MLBPA.
The 2016 Arizona Fall League experimented with a 15-second pitch clock and additional timers for other game situations (35 seconds between batters and 30 seconds for mound visits). The 2016 AFL also experimented with a three mound visit/conference limit per team, per game.

This is all in addition to Minor League Baseball's use of pitch clocks, which have existed in one form or another since well before the 2017 offseason. MiLB does not have a bartering partner as formidable as the MLBPA.

At a November 2017 owner's meeting, Manfred all but assured baseball's brass that pace of play rules changes will be implemented in time for the 2018 regular season, with or without MLBPA support. The changes are owner-friendly and corporate hopes it will help the brand—from the big prize of keeping fans engaged with on-field action to smaller fringe benefits, such as cutting payroll expenses as hourly stadium employees spend less time at work or being able to shut the lights off 10 minutes earlier, an average savings-per-game predicted by the commissioner's office. Cue Article XIII.
Related PostRob Manfred Vows Pace of Play Rules Changes for 2018 (11/16/17).

MLB will purportedly introduce a 20-second pitch clock for all situations—both "bases empty" and "runners on" scenarios—starting when the pitcher has the ball on the mound and stopping when the windup begins, or the pitcher comes set, in a form similar to that first introduced at the 2014 AFL.

As has been practice in the minors, this pitch clock will reset if the pitcher steps off the rubber, while the batter must enter the box within five seconds of the clock starting; pitchers who fail to windup or set prior to the expiration of time will be warned, after which any subsequent violation will result in an automatic ball.

A 30-second between-batters clock, similar to the 2016 AFL model, is also expected to make an appearance in 2018; the rejected proposal had included a 35-second between-batters timer.

Mound visits are about to change.
Another initiative likely to see implementation concerns mound visits, and will expand the current definition of a mound visit—which presently occurs when a coach or manager enters the field to confer with a pitch—to include players, such that a pitcher conferring with a first baseman, for instance, shall be charged a mound visit, the second of which within an inning would require the pitcher to leave the game, as in OBR 5.10(l) regarding "Visits to the Mound."

Sidebar: In our 2017 postseason live blog, we noted that catchers were visiting the mound to confer with pitchers to a point of excess; the proposed change would limit their ability to do this.

For reference, Rule 5.10(l) presently reads, in part (circa 2017):
(1) This rule limits the number of trips a manager or coach may make to any one pitcher in any one inning;
(2) A second trip to the same pitcher in the same inning will cause this pitcher’s automatic removal from the game
The Clubs had purportedly proposed six allowed "no-charge" conferences per game, which would have allowed players to confer with the pitcher without invoking the mound visit rule up to six times per game; instead, MLBPA's rejection means that Manfred and the Clubs are free to implement any pace-of-play proposal first introduced in Winter 2016 or earlier, which includes the aforementioned pitch clocks, between-batters clock, and mound visit restrictions.
