Ohlendorf has not been stellar this season at Syracuse, with a 4.27 ERA in 12 starts, but struck out eleven in his last two starts while allowing just one total run in 12.2 IP. Hopefully he can carry his momentum to the majors with him.
Karns struggled in his brief MLB stint, with a 7.50 ERA in three starts. However, not too much can be expected of a guy straight out of Double A. His demotion is more notable in that it means at least one of Stephen Strasburg or Ross Detwiler will return soon. The answer is likely Detwiler, who looked great in his rehab start on June 8th. He should re-enter the rotation on the 13th in Colorado or the 14th in Cleveland. Ohlendorf will stay with the Nats in Strasburg’s rotation spot until he is able to return. That could be as early as Sunday, given that Strasburg had a successful simulated game recently. As much as the Nats want Ohlendorf to succeed, they can’t wait to send him back down and have their rotation be whole again.
