DETROIT -- Orioles pitcher Wei-Yin Chen could rejoin the team before the All-Star break as the lefty continues to progress favorably from a left oblique strain.
"If everything goes well, he'd be an option for us in early July," Orioles manager Buck Showalter said on Monday. "First week of July."
Chen, who is at the team's spring facility in Sarasota, Fla., threw a 45-pitch bullpen session on Monday and will throw a simulated gamed on Thursday. Showalter said Chen, who has now thrown off a full mound twice, would have another simulated game after that.
Chen was placed on the disabled list on May 14 (retroactive to May 13) and went 3-3 with a 3.04 ERA in his first eight starts.
Orioles to recall Britton for Tuesday start in Detroit
DETROIT -- The Orioles will recall left-hander Zach Britton to start Tuesday's game against the Detroit Tigers, as righty Jason Hammel continues to work back from a stomach virus.
"He's still pretty weak, but he's getting better every day," Orioles manager Buck Showalter said of Hammel, who has been sick since Friday and stayed away from the clubhouse for the first couple days of his illness.
"The good news is we got contingency things in place," Showalter said. "People that are capable of doing well. We got [Chris Tillman] there Wednesday and the off-day there [on Thursday]. I don't think you are looking at DL with [Hammel]. Obviously you are going to have some backdate there, [but] you don't want to lose him for six or seven days if you don't have to. The other problem, too, if you put him out there and he's weak and only able to go an inning or two, then you are really putting some people in harm's way."
Hammel was out on the field for Monday's pregame session in Detroit, and given that Tillman is slated to go Wednesday afternoon, it's likely the team will have Hammel make his next start following Thursday's off-day.
Hammel was originally slated to start Monday's game, but right-hander Jake Arrieta got the nod in his place. The Orioles optioned Arrieta following Monday's 5-1 loss, with the corresponding roster move expected to be Britton.
Britton will be making his second big league start this year and has gotten positive reports on his past few outings for Triple-A Norfolk. In 11 Minor League starts, the lefty has a 3.28 ERA and has allowed 28 runs (22 earned) on 65 hits and 23 walks. He has struck out 44 over 60 1/3 innings. Britton's lone start for the O's this year came against Seattle, and he surrendered six earned runs on 10 hits and two walks over six innings.
Gonzalez leaves park, attends daughter's birth
DETROIT-- Orioles starter Miguel Gonzalez left the team prior to Monday's 5-1 loss to the Tigers in Detroit to catch a flight to Southern California for the birth of his daughter with wife Lucia.
Leah Gonzalez, born Monday night, is the couple's first child.
Gonzalez, who picked up the win in the Orioles' 6-3 victory over the Red Sox on Sunday, is expected to be placed on paternity leave, although that hasn't officially happened yet -- and manager Buck Showalter said following Monday's game that it's not definite.
The right-hander could theoretically not miss a start, particularly with Thursday's off-day, but the Orioles would still be afforded the luxury of having an extra player anywhere from 1-3 days if Gonzalez is on paternity leave.
• Pitcher Tsuyoshi Wada, in his first outing since being activated from the disabled list and optioned to Triple-A Norfolk, went 6 2/3 innings and allowed a run on five hits Monday. He struck out eight and didn't issue a walk, exiting to a standing ovation.
• The Orioles agreed to terms on Monday with fourth-round Draft pick Jonah Heim. Heim is a switch-hitting high school catcher who had committed to Michigan State.
• Brian Roberts was among several Orioles who took early batting practice on Monday, and Showalter said Roberts, who is on the DL with a hamstring injury, has done pretty much everything but run in short bursts.
