Manager Don Mattingly says the hip has been bothering Hairston for several months and flared up again during a 7-3 loss to Miami on Saturday night. Hairston left the game early and did not play in Sunday's series finale.
Hairston is batting .273 with four home runs and 26 RBIs in 78 games but has struggled since the All-Star break, hitting .212 in his past 21 games. He missed 16 games in May with a left hamstring strain.
Mattingly says Herrera gives the Dodgers needed flexibility. Herrera is hitting .243 with one home run and 16 RBIs in 51 games.
