Ryan Zimmerman played seven innings in left field at Class A Potomac on Sunday afternoon — his third straight day of playing on his minor league rehab assignment — and had no physical issues, according to Nationals Manager Matt Williams. Zimmerman, who has missed 44 games with a fractured right thumb, is next scheduled to play nine innings on Monday with Potomac, Williams said.

Zimmerman went 2 for 4 with an RBI single and an RBI double on Sunday. Williams said, based on the team’s reports from the game,  Zimmerman was caught in a rundown on the bases and slid headfirst into third base.

When telling reporters about the rundown, Williams breathed a deep sigh of relief, happy Zimmerman didn’t get hurt again. Zimmerman originally broke his thumb diving back to second base on a pickoff.

Zimmerman had several chances while in left, where two doubles and a single were hit toward him. He also caught one flyball — a blooper to left field — calling off the shortstop to make the catch on the run.

“Did fine,” Williams said. “So he’s got another one [Monday].”

The Nationals and Zimmerman have targeted a potential Tuesday return for the veteran. Williams is expected to watch Zimmerman’s Monday rehab game on the Nationals’ day off.
