Manager Joe Espada said that Bregman was not included in Friday's lineup against Kansas City due to elbow soreness, Chandler Rome of The Athletic reports.
Bregman missed five games in August due to swelling in his right elbow, though he had started each of the Astros' prior nine games before Friday. It's unclear if the third baseman will be available off the bench for the contest. Over the nine games since his return, Bregman has gone 9-for-36 with two solo home runs.
