Louisville has forced a deciding game against Missouri in their NCAA tournament regional. The issue was forced when Louisville 3rd baseman/pitcher Chris Dominguez hit a game-winning 2-run shot in the 8th inning. But it wasn't the home run that forced every issue, especially the Tigers being hot under the collar. That issue was forced by Dominguez 's behavior as his celebration became rather external:
Louisville third baseman Chris Dominguez beat the Tigers with a two-run
eighth-inning home run deep into Missouri’s left-field bullpen. Then
Dominguez, throughout his trot around the bases, verbally taunted the
Missouri players. He turned backward. He hopped up and down. He
gestured toward a Missouri team straining to stay on the top step of
its dugout.
...When Louisville took up its defensive positions for the bottom of the
eighth, Dominguez was apparently still on the offensive. Suddenly, the
Missouri dugout, located just a short sprint from Dominguez at third
base, erupted in a collective roar.
In a recent paper that appeared in Economic Inquiry, (a discussion of which is in JC Bradbury's excellent book The Baseball Economist), Bradbury and Doug Drinen. found evidence that the price of throwing at batters is an important determinant in the number of hit batsmen. Pitchers were more likely to hit batters when the price of doing so was low. For example, if the Cubs are up by 9 in the 8th inning and their bullpen is fresh, hitting a batter puts a runner on base and it could get the pitcher tossed out. But a 9-run lead is hard to over come in general, let alone after the 7th inning. One extra runner doesn't mean much and there are plenty of fresh pitchers in the bullpen.
But today's game between Louisville and the Tigers is do-or-die and the stakes are high. The winner advances. The loser goes (or, god forbid, stays) home. So if retaliation is going to occur, it will occur when the "price" of doing so is low, if the game is out of reach in the late innings.
There may be other things that happen throughout the game that can be retaliatory: a player going spikes up into second, close inside pitches, an extra hard slide into home. But if Louisville or Mizzou is up big late in the game, Mr. Dominguez may want to watch his chin when he comes up to bat.
