The Chicago Cubs' Starlin Castro left in the bottom of the fourth inning after pulling up on a ground ball to shortstop Wednesday during an 11-7 loss to the Los Angeles Dodgers.
The Cubs said their shortstop had left hamstring tightness and was being evaluated.
Aaron Harang, bidding for a spot in the Dodgers rotation, allowed four runs, five hits and a walk in the first, then threw a 1-2-3 second.
Jerry Hairston Jr. hit a two-run double off Trey McNutt in the second inning and added a sacrifice fly in the third. Darwin Barney had two singles and two RBIs.
Alfredo Amezaga had three hits and two RBIs for the Dodgers, who trailed 4-1 after the first but led 8-4 in the middle of the third.
