Here’s a weird one: Tensions flared and benches cleared in a game between the Chicago White Sox and Detroit Tigers over White Sox ace Chris Sale’s apparent belief that the Tigers had someone set up in center field to steal signs. First, Sale tipped his cap toward the outfield after striking out Victor Martinez in the third:

Then, with one out in the sixth, Sale plunked Martinez in the left shoulder. The two exchanged words as Martinez took his time walking to first, and both team’s benches cleared soon after Sale again motioned out to center field.

TV cameras also spotted Sale mimicking binoculars in the dugout. And Tigers infielder Ian Kinsler mocked Sale in turn:

After the game, Sale denied having any concern that the Tigers were stealing signs:

If there intent behind the plunking, Sale must not have realized how much it would ultimately help the Tigers. Martinez came around to score the tying run, and Detroit added five more across the seventh and eighth and won, 6-1. The Tigers entered play Wednesday one game ahead of the Kansas City Royals in the AL Central, and reduced their magic number to four with the win.
