Olsen’s next rehab start Thursday

Left-hander Scott Olsen will make his next rehab start on Thursday for Single-A Potomac at Winston-Salem, the Nationals announced this morning. Olsen, who is recovering from an inflamed left shoulder, should go five innings, and could be in one of his final rehab starts before returning to the big leagues.

He allowed an unearned run over four innings in his start for Single-A Hagerstown, striking out five and allowing two hits.

Olsen has been on the disabled list since May 23. He’d been one of the Nationals’ more impressive pitchers early in the season, but left a May 21 game against the Orioles after three innings when he felt discomfort in his shoulder. He’s spent most of the last two months on a throwing program in Viera, Fla.
