Chicago White Sox manager Tony La Russa expressed disappointment in Yermin Mercedes after his designated hitter swung at a 3-0 pitch in the ninth inning of a game the Sox were leading 15-4 over the Minnesota Twins on Monday night.
He smashed the 47 mph pitch over the centerfield fence for his third hit of the game.
"Big mistake," La Russa said on Tuesday afternoon. "The fact that he's a rookie, and excited, helps explain why he just was clueless. But now he's got a clue."
Because of the large deficit, the Twins were pitching infielder Willians Astudillo at the time.
