Pederson, playing center field, made a diving attempt at a bloop single by Iowa left fielder Josh Vitters to right center field with two outs in the first inning. Pederson immediately left the game.
Dodgers manager Don Mattingly in Kansas City confirmed Pederson's right shoulder injury, which is not believed to be serious. The outfielder will undergo tests on Wednesday in Albuquerque.
Mike Baxter replaced Pederson, playing right field, with Trayvon Robinson moving from left field to center and Jeremy Hazelbaker moving from right to left field.
Here is a picture of Pederson with Isotopes after the injury with manager Damon Berryhill and trainer Yosuke Nakajima, per MiLB.com:
