White Sox center fielder Luis Robert exited Game 4 of the ALDS on Tuesday with right leg tightness.
Adam Engel replaced Robert in center in the top of the seventh inning with the White Sox trailing the Astros 6-1.
Robert hit third in the order on Tuesday and registered one of the Sox five hits at the time of his exit.
He's been one of their most productive hitters in the series vs. Houston, going 7-for-15 in the four games with a pair of walks.
