Reddick is hitting .167/.247/.167 against left-handed hitters this season, 11-for-66 with no extra-base hits and seven walks. In his career, Reddick has hit .222/.286/.371 against left-handers.
"I know [Reddick] feels he's an everyday guy. I've seen him play every day in stretches, and have quality at-bats against left-handed pitching," said general manager Farhan Zaidi on Monday. "The fact that he brings Gold Glove-caliber defense adds to the value of him being out there every day. That's ultimately a question for [Dave Roberts], if he wants to address it."
Scott Van Slyke gets the start in right field in place of Reddick.
Kiké Hernandez plays left field with Howie Kendrick at second base. Chase Utley sits, though a pair of left-handers in Adrian Gonzalez and Joc Pederson are in the lineup.
For Pederson, it's just his fourth start all season against a southpaw. He is 4-for-32 with a home run, a double and five walks against left-handers this season.
A.J. Ellis gets the start at catcher.
