Sunday's College World Series championship finale featured two ejections: Coastal Carolina head coach Kevin Schnall and 1B coach Matt Schilling by HP Umpire Angel Campos (formerly MLB, now NCAA Division 1). Were the ejections justified or overly aggressive, as the broadcast (and Schnall in a post-game press conference) suggested? Let's break it down.
In the first inning, 1B coach Schilling left the first base coach's box and walked toward home plate to argue balls and strikes after HP Umpire Campos called a strike during a stolen base attempt. Campos then issued a balls/strikes warning to Coastal Carolina (which is how it's done in NCAA baseball).
Chanticleer head coach Schnall (yes, that's their school mascot) then exited the dugout, in his words, to seek clarification on the warning. But when Campos responded it was a balls/strikes warning, Schnall responded by gesturing a number three with his hand while exclaiming, "you missed three pitches."
Because Schnall left his position (leaving the dugout) to argue balls and strikes after directly being warned not to continue arguing balls and strikes, he was ejected from the game.
Interesting note: NCAA Rule 3-6-f states, "If a coach leaves the dugout or their position to argue a ball or strike call (including a half swing or hit-by-pitch), the coach may be ejected without warning."
Schnall then continued arguing while walking toward home plate, eventually engaging with other umpires who had arrived to assist. One umpire fell and upon standing issued Schnall a two-game suspension (which, again, is a college-specific procedure) pursuant to NCAA Rule 2-26 regarding excessive arguing after being ejected: "No team personnel may continue to argue or to continue to excessively express themselves with prolonged actions or offensive language after an ejection. Penalty: An additional two-game suspension."
To conclude, the ejection followed a warning pursuant to the book—my only gripe is Campos' "shoo fly" gesture, which the head coach took offence to (as did I). The shooing gesture is not just an unapproved mechanic, it rarely if ever actually works to diffuse a situation. Instead, a firm stop sign might have done the trick, but considering this coach's aggressive posture regarding "you missed three pitches," I would surmise the ejection would likely have occurred either way.
