Chicago White Sox starting pitcher Hector Santiago got so wrapped up in his dominant performance against the New York Mets on Tuesday night that he forgot to bat. Interleague play can be tricky for American League pitchers. For the majority of the season, they don’t even have to think about swinging a bat. Despite the fact that his team was playing in a National League ballpark on Tuesday, Santiago chose to continue not thinking about it.

As you can see, the game was delayed in the top of the sixth inning when someone had to go into the clubhouse and tell Santiago it was his turn to hit. The left-hander was in the midst of a full-fledged pitchers’ duel at the time. He gave up only four hits and no earned runs in seven innings of work, but New York went on to win 1-0 in the 10th inning as Mets pitcher Matt Harvey threw nine innings of one-hit ball and took a perfect game into the eighth.

To make matters worse, Santiago is a native of North Jersey. According to the Chicago Sun-Times, several of his family members were in attendance at Citi Field to watch him pitch against the team he grew up rooting for. Forgetting an at-bat is embarrassing, but the way he pitched certainly was not.
