NEW YORK—Orioles right-hander Jason Hammel threw five shutout innings in a minor league rehab assignment start at advanced Class-A Frederick on Saturday night.
Hammel, who had arthroscopic surgery on his right knee in mid-July, held the Carolina Mudcats to three hits, all singles, while striking out seven and walking one. He threw 66 pitches (47 strikes), just under his 70-pitch limit.
"Jason threw all his pitches for strikes and looked comfortable," Duquette said by text message. "[He] finished up his work in [the] 'pen."
Hammel could also make one more rehab start, this one for Double-A Bowie, which is in the Eastern League playoffs.
“[We] just kind of want to see how he feels physically,” Orioles manager Buck Showalter said earlier today. “If he’s not favoring [the knee] at all. I think the last hurdle is the mental part of it and not thinking about it. I don’t care how many sim games [he gets], it’s good to get in the game environment like that.”
Regardless, Hammel will join the Orioles in Toronto this week to throw a bullpen session.
Hammel, acquired from the Rockies this offseason as part of the trade that sent Jeremy Guthrie to Colorado, emerged as the Orioles ace this season. He is 8-6 with a 3.54 ERA in 18 starts, allowing 97 hits and striking out 106 in 109 1/3 innings pitched.
