Oakland Athletics right-hander Chris Bassitt was carted off the field Tuesday night after he was struck on the side of the head by a line drive in the second inning against the Chicago White Sox.

With two on and no outs, Bassitt threw an 89.5 mph cut fastball that Brian Goodwin drove right back up the middle. Bassitt went down on the mound right after he was hit, holding his head, and his teammates quickly waved to the dugout for assistance.

The 32-year-old Bassitt, who broke into the majors with the White Sox in 2014, is in the midst of a breakout season for Oakland. He was 12-3 with a 3.06 ERA in 24 starts heading into the game, leading the AL in victories.
