BALTIMORE -- Orioles starter Brian Matusz (strained left intercostal muscle) will make a third rehab start on Friday for Triple-A Norfolk and could be activated as early as the series finale in Seattle on June 1.
Right now, it's about 50-50 whether Matusz's next outing will be his last for an affiliate as the team has been cautious in bringing the 24-year-old Matusz along. Given the amount of time Matusz has missed -- he was placed on the disabled list retroactive to March 30 -- manager Buck Showalter likened Matusz's rehab to a full Spring Training of sorts.
"If he pitches well and the people that are evaluating like what they are seeing ... then he can come back and pitch for us on the first," Showalter said of Matusz, who has logged 10 Minor League innings in addition to a pair of starts at extended spring training. "If not, he'd take another start on the first somewhere else other than here, or in Seattle in that case."
Matusz, who is scheduled to throw around 90 pitches Friday, said he felt it was the "right move" for him to get at least one more start.
"I think it will be good for me," said Matusz, who threw a side session prior to Tuesday's game. "I'd like to go out there and throw more than six innings, and get a little more pitches under my belt as far as coming up here and competing at the big league level."
The team's No. 2 starter, Matusz went 6-0 with 1.57 ERA in his final eight starts in 2010, leading American League rookies in strikeouts (143), innings pitched (175 2/3) and games started (32). He went six innings or more in 20 of those starts, and will help add consistency to the Orioles rotation.
Matusz tossed six scoreless innings for Double-A Bowie Saturday night, allowing three hits and a walk in the 70-pitch outing. His activation will force Chris Tillman or Brad Bergesen to Triple-A or to the bullpen.
Lee scheduled to report to extended spring
BALTIMORE -- First baseman Derrek Lee, who is on the 15-day disabled list with a left oblique strain, will report to extended spring training on Wednesday in Sarasota, Fla., and could return to the Orioles' lineup as early as June 1.
Manager Buck Showalter said he wants the 35-year-old to return to baseball activities and return to the batter's box, no matter where it is.
"I'm not gung-ho about him taking them [at-bats] in extended spring too much, playing dodgeball," Showalter said of Lee. "I asked him about it and he said, 'Well I've never done it before,' so he doesn't really know."
Lee had been hoping to avoid being put on the DL, saying that he felt much improved since being removed from Baltimore's game against the Red Sox on May 16. The veteran had been bothered by discomfort in his left side for weeks, and he aggravated the muscle further while running the bases during his first at-bat at Fenway Park.
An unusually abrupt Lee said on Saturday that he doesn't anticipate a long period of rehab that would involve him going to extended spring training and working his way back, although Showalter said regardless of the exact plan, Lee will have to get some at-bats to test the oblique.
"That's what it is, 15 days," Lee said. "That's what I've got to wait."
Bergesen will take his next turn against A's
BALTIMORE -- Starter Brad Bergesen will make his next start on Saturday in Oakland, and will be available in the bullpen on Tuesday and possibly Wednesday against the Royals, if needed.
Manager Buck Showalter confirmed that Bergesen, who was skipped from the Royals series with Monday's off day, will get the ball against A's lefty Josh Outman. Following Zach Britton on Tuesday will be Jake Arrieta, Jeremy Guthrie and Chris Tillman, who threw in Sunday's series finale. Tillman and Bergesen are both pitching to stay in the O's rotation when Brian Matusz returns, which could come as early as June 1.
If Bergesen is the odd man out, he could be moved to the bullpen on a more permanent basis. The 25-year-old Bergesen made the Opening Day roster in the swingman man/extra starter spot and is 1-5 with a 5.64 ERA in nine games (eight starts). He lasted just 3 1/3 innings in his last start on Thursday against the Yankees, giving up eight earned runs on the heels of a complete-game shutout against Tampa Bay.
Pitcher Jason Berken, who was demoted to Triple-A Norfolk after Friday night's game, made his first start for the Tides on Tuesday afternoon -- pitching three scoreless innings with five hits and three strikeouts. The Orioles are stretching Berken out to be a starter, not necessarily as a role change, but because they think it's in the reliever's best interest right now.
Cesar Izturis underwest successful surgery on Tuesday morning, which involved moving the ulnar nerve in his right elbow. The O's remain hopeful he can play for them at some point this season. Izturis is currently on the 60-day DL.
Justin Duchscherer is still at extended spring training, although there are no plans right now for him to get back into a game. Duchscherer (left hip strain) was shut down last week prior to making a scheduled three-inning outing.
O's top prospect Manny Machado (dislocated left knee cap) has been hitting in the cages and taking batting practice at extended spring training. The shortstop also started light running on Monday and is expected to remain in Sarasota for the next few days.
