Cruz exited Sunday's 4-3 win over the Royals in the seventh inning due to a left ankle injury, Andrew Destin of the Pittsburgh Post-Gazette reports.
Cruz is dealing with left ankle discomfort after slipping in the outfield according to manager Derek Shelton. Shelton said that the 26-year-old "was able to run" and that it later "stiffened up." Cruz finished his day 1-for-2 with a walk and a run scored against Kansas City. The Pirates will start a four-game series in St. Louis on Monday, and it's unclear if Cruz will be ready to go for the opener.
