BALTIMORE - The Baltimore Orioles placed starting pitcher Wei-Yin Chen on the 15-day disabled list Tuesday with a right oblique strain he suffered on Sunday in Minnesota. The left-hander pitched five scoreless innings before exiting.
He is 3-3 with a 3.04 ERA in eight starts this season. This is Chen's first DL stint of his career, as last season he started the most games of any Orioles starter.
"I'm real disappointed right now about my injury," Chen said through his interpreter. "The only thing I can do is just heal up very fast and just come back sooner and help the team."
Chen is the second Baltimore starting pitcher to be placed on the DL in the last week, as Miguel Gonzalez was placed on the 15-day DL with a blister on his right thumb.
Orioles manager Buck Showalter said Chen will stay with the team through the current homestand, while his wife and son are in town, and then report to Sarasota, Fla., next Tuesday.
Chen said he is not sure when in Sunday's game he injured his oblique, and that right now, there's not much he can do.
"The only thing I can do right now is just help myself," Chen said, "and get better and not do anything to get any worse."
PAIR OF CALL-UPS: The Orioles called up infielder Yamaico Navarro and reliever Alex Burnett to fill the two open spots on the roster.
It is the third time Burnett has been called up this season. He made his Baltimore debut last Thursday against the Royals, pitching a scoreless inning.
Burnett is 1-0 with a 1.86 ERA in eight games with Class-AAA Norfolk.
"My mindset is I'm going to do whatever is best for the organization," Burnett said. "When I can go down there and be available whenever they need me is something that I try to work on."
Navarro was with the Orioles for the first two home games of the season, but never got into a game. He has hit .303 with two homers and 13 RBIs for Norfolk in 34 games.
Navarro has mostly played second base and shortstop for the Tides, but he said he's open to play anywhere for Baltimore.
"I'm very excited," Navarro said. "My swing right now's great. I've played very well."
OTHER INJURY UPDATES: Gonzalez played catch Tuesday and Showalter said his rehab assignment could come soon. Showalter added that Gonzalez may only throw a few innings in his rehab start.
Starting pitcher Tsuyoshi Wada is making a rehab start for Norfolk Thursday at 12:35 p.m. Starting pitcher Jake Arrieta threw a bullpen session for Norfolk Tuesday to test his strained right shoulder.
Second baseman Brian Roberts started on the stationary bike on Tuesday. Backup catcher Taylor Teagarden is going to see a hand specialist in Sarasota, Fla.
STARTING PITCHERS: Freddy Garcia (0-1, 4.26 ERA) will pitch against the Padres at 12:35 p.m. Wednesday, facing Jason Marquis (4-2, 3.48). Jason Hammel (5-1, 4.93) will pitch against the Rays on Friday, but the Orioles will need a starter for Saturday's game.
Showalter said Jair Jurrjens is an option. Jurrjens is 4-1 with a 3.14 ERA in eight starts for Norfolk.
