Manager Rob Thomson said Saturday that Marsh and Johan Rojas will split center field work but won't be in a straight platoon, Corey Seidman of NBC Sports Philadelphia reports.

EDGE Analysis

Marsh had been the Phillies' starting left fielder against right-handed pitching but the team is opting to deploy Austin Hays in left every day. Instead, Marsh will slide to center field. The lefty-hitting Marsh is expected to start most games against right-handed pitching while Rojas starts against lefties. Still, Rojas could see some work against right-handers. Marsh is slashing .247/.325/.410 with nine homers and 12 stolen bases this season.
