Machado undergoes successful surgery

BALTIMORE -- Manny Machado underwent successful surgery to repair the torn medial patellofemoral ligament in his right knee on Wednesday in Los Angeles, Orioles manager Buck Showalter said.

Machado had the surgery at 6 a.m. PT (9 a.m. ET), and the third baseman will remain in L.A. for the next three weeks to begin his rehab. Showalter isnt sure yet whether Machado will go straight to Sarasota, Fla., or return to Baltimore for the Orioles' three-game series against the Red Sox from Sept. 19-21.

The recovery time for Machado is still expected to be 4-6 weeks -- the same length his left knee injury kept him out after having surgery in October last year. The difference this time is that his surgery comes almost two months earlier, meaning the former All-Star could return in time to have a normal Spring Training, assuming there are no setbacks.

"I wanted to have Spring Training next year," Machado said on Monday before departing for the West Coast. "If we waited for the surgery a little longer, it was going to be tough."

Gausman optioned, but will return for next start

BALTIMORE -- After an outing that tied the shortest start of his career in Wednesday's 3-1 loss to the Rays, Kevin Gausman is heading for another brief stint in the Minors -- but it's not because of his performance.

Like the Orioles' decision to option Wei-Yin Chen earlier in the day, this move is made with the intention of maximizing every roster spot until September callups.

Like Chen, Gausman will technically join the Gulf Coast League Orioles, whose season ends on Thursday, and return in time for his next start on Monday when rosters expand. Because the GCL season is coming to an end, the O's won't need to wait the usual 10 days to bring Gausman back to the Majors, and he will still be able to make his next start on turn.

The Orioles didn't announce a corresponding move on Wednesday, but after having their starter go fewer than five innings on consecutive nights, an extra relief pitcher could be of use in Baltimore.

Unlike Chen's situation, the O's won't have to send anyone down to bring Gausman back to the Majors because teams will be allowed to carry up to 40 players on the active roster starting on Monday.

O's temporarily option Chen, add Clevenger

BALTIMORE -- With just days until rosters expand from 25 to 40, the Orioles took an opportunity on Wednesday to juggle their pitching staff one more time.

The O's optioned lefty Wei-Yin Chen to the Gulf Coast League Orioles a day after his most recent start and recalled catcher Steve Clevenger from Triple-A Norfolk. The GCL O's season ends on Thursday, so Baltimore will be able to bring Chen back to the Majors in time for his next scheduled start, Sunday, without waiting the typically necessary 10 days.

The O's will have to make one more roster move on Sunday to reactivate Chen, but they can expand their roster to as many as 40 players on Monday.

The move on Wednesday was made with the intention of getting the Orioles' bench back to a normal size. The addition of Clevenger gives Baltimore four players, including three left-handed hitters.

"We've been playing short a position player for a while, and we thought this was an opportunity to take care of that problem," manager Buck Showalter said. "Give us a better chance to win tonight is what it's about. Better chance to win tomorrow night."

Clevenger batted .240 with eight doubles in 26 games with Baltimore this season and has hit .305 in 64 games for Norfolk. He was viewed as a likely candidate to join the team as a third catcher when rosters expanded. His addition a few days early caught Clevenger a bit off guard.

"They caught me a little surprised last night," Clevenger said. "I was just down there playing, hoping to play good enough to get a callup."

Showalter didn't rule out the possibility of making a similar move with another of his starters with Minor League options remaining.

Kevin Gausman, Bud Norris and Miguel Gonzalez -- all of whom have spent time in the Minors this season -- will pitch for the O's the next three days. If the Orioles need more bench help or an extra arm, they won't hesitate to make another move.

"We'll consider anything that gives us a better chance to win the game that night and doesn't jeopardize anything we're doing in the future," Showalter said.

Worth noting

• Top pitching prospect Dylan Bundy met with vice president of baseball operations Brady Anderson on Tuesday to lay out his offseason plans. Bundy won't go to instructional league and will join the Orioles for their minicamp in Sarasota in January.

He's being treated as a healthy pitcher -- "Which is what he is," Showalter said.
