Boston Red Sox ace Chris Sale was admitted to Massachusetts General Hospital on Sunday due to a stomach illness, according to Pete Abraham of the Boston Globe.
He is expected to stay overnight for observation.
Sale started Game 1 of the American League Championship Series against the Houston Astros on Saturday night, allowing two runs in four innings of an eventual 7-2 loss.
The pitcher certainly hasn't disappointed during his time in Boston when healthy. In 2017, he went 17-8 with a 2.90 ERA, 0.97 WHIP and a career-high 308 strikeouts in a career-best 214.
