New York Yankees center fielder Curtis Granderson left Saturday's game against the visiting Baltimore Orioles with a tight right hamstring and underwent an MRI.
He exited the game after striking out looking on a checked swing in the second inning.
Nick Swisher moved from first base to right field, Andruw Jones went from right field to left field, Ichiro Suzuki moved over from left field to center and Steve Pearce entered the game at first base.
Granderson is hitting .235 with 34 home runs and 79 RBI but just .176 in his last 22 games. He is tied for second in the majors with 159 strikeouts.
First baseman Mark Teixeira, out with a strained left calf, is expected to be out until at least next week. Manager Joe Girardi said third baseman Alex Rodriguez "came out all right" and "reports are good" after his first rehab game Friday in Tampa, Fla., for a fractured left hand. Left-hander Andy Pettitte, who has a fractured left ankle, threw off a mound Friday but it is uncertain when he will throw again.
