Starting pitcher Chris Sale was released from the hospital on Monday after being kept overnight for observation because of a stomach illness, the Boston Red Sox announced.
Red Sox ace Sale will re-join the team in Houston on Tuesday and is slated to start against the Astros in game five of the MLB American League Championship Series.
Sale started Saturday's ALCS opener against the Astros, allowing two runs and walking four in Boston's 7-2 loss.
The 29-year-old left-hander allowed two runs and struck out nine over 6.3 innings in the Red Sox's four-game AL Division Series win over the New York Yankees.

The seven-time All-Star spent his first seven seasons with the Chicago White Sox before he was traded to Boston in December 2016.
