Reimold activated from DL, inserted into lineup

CHICAGO -- The Orioles activated Nolan Reimold from the disabled list prior to Tuesday's game against the White Sox and inserted him into the starting lineup, batting eighth and playing left field.

Reimold last played for Baltimore on May 11 and had been on the DL with a right hamstring strain that had hampered him since Spring Training.

"I expected it to take a little bit of time to heal up and then get the at-bats that I needed," said the 29-year-old Reimold, who posted a .196/.255/.304 line in 12 games for Double-A Bowie. "The team was playing well, guys were hitting, playing well, when I wasn't here. So there wasn't a huge rush to get back. Just wanted to make sure everything was good to go before I came here."

Reimold, a right-handed hitter, could get a few starts this week with the Orioles slated to face lefty starters John Danks, Hector Santiago and Jose Quintana in the White Sox series.

Before going on the DL, Reimold appeared in 31 games for the Orioles, batting .188/.257/.327 with a .242/.265/.424 line against left-handed pitching.

"I want Nolan to get his feet wet, just like [Brian Roberts] did DH-ing and now he's going to play second," manager Buck Showalter said. "I just want to go into the All-Star break with a good idea of what we have and what we don't have and what we can expect from these guys. It's encouraging to be getting some of these guys back."

Reimold finished Tuesday's 5-2 loss 1-for-3 with a single and a strikeout.

Chen to make rehab start Thursday at Double-A Bowie

CHICAGO -- Orioles pitcher Wei-Yin Chen will make one more rehab start, for Double-A Bowie on Thursday, and the organization hopes to have him back within a week or so.

"I want to be fair to him and to our team in the bullpen," Orioles manager Buck Showalter said of the decision to have Chen pitch another rehab game.

"Billy [Castro, bullpen coach] knows him real well and Rick [Adair, pitching coach] does, and that played a big part. Billy thought he was really close and needed one more start to be sure. … The last thing I told him was, 'Go down there and win. Go down there and pitch like you're trying to win that game for Bowie.'"

Chen, who has been on the disabled list with a left oblique strain, pitched for Bowie on Saturday night and went five innings, allowing four runs on five hits and two walks. All four of his runs came in the fifth. Showalter said the plan is to get Chen to go around 90 pitches on Thursday.

"I'm hoping that's his last start there," Showalter said of Chen, who will help stabilize a rotation that added Scott Feldman on Tuesday in a trade from the Cubs. "That kind of figures into some things we're doing, too. We had to get through his first outing there to see where we were in order to push the timeline a little bit up on this trade."

Chen has been sidelined since sustaining injury his May 12 start against Minnesota. He is 3-3 with a 3.04 ERA in eight starts this season.

Feldman to start Wednesday in rotation shuffle

CHICAGO -- New Oriole Scott Feldman is expected to join the team in Chicago on Tuesday night and make his debut for Baltimore on Wednesday as part of a rotation shuffle.

Lefty Zach Britton will now pitch Thursday's series finale, which pushes right-hander Miguel Gonzalez --originally slated for Wednesday-- to Friday's series opener in New York.

"He always seems to benefit from some extra rest," Showalter said of Gonzalez. "And it fits well. I just didn't want Scotty to sit around for a week between pitching. He's already working on some extra time."

The O's will have to clear a 25-man roster spot for Feldman, and rookie Kevin Gausman could be the guy to go. Gausman is currently in the bullpen in long relief and the O's could opt to send him to Norfolk to have him consistently start. They could also opt to send down a position player and, with a roster that closely resembles Opening Day, Chris Dickerson or Danny Valencia are two possibilities. Valencia has an option, while Dickerson does not, so he would have to clear waivers.

Feldman last pitched on June 26, and he is 4-2 with a 4.20 ERA in 14 career games (eight starts) against the White Sox. He is 2-1 with a 6.23 ERA in six games (three starts) at U.S. Cellular Field.

"He's a guy with some American League background," Showalter said of Feldman, who pitched for him with the Rangers. "Scotty is what he is. He's a competitive guy. Haven't seen him in a while. He's had a couple things in his arsenal that are a little different than when I had him. He was more of a relief pitcher there, had a little different arm angle. There's a lot of things that work in his favor. He's been in the American League. Should be a pretty seamless transition to the locker room."
