BALTIMORE -- Right-hander Bud Norris, who is in the midst of a career-high four-game winning streak, was placed on the 15-day disabled list with a strained right groin before Friday's series opener against the Rays.
Norris felt soreness in his groin last Saturday in a 6-1 win against the Yankees and left the game after five innings. The 29-year-old was a little tentative in his between-starts bullpen session Wednesday and underwent an MRI Thursday, which revealed the strain.
"It wasn't what they wanted to see," Norris said of the MRI results.
"It's kind of frustrating because I've been throwing the ball so well and obviously I want to keep playing, but I've got to get this thing right. We still have a lot of season left, we're not even at the [All-Star] break yet, so hopefully I can just let this thing calm down, get back to 100 percent and get back out there."
Norris is 7-5 with a 3.62 ERA in 14 starts and has allowed two runs over his last 19 2/3 innings. He was placed on the 15-day DL retroactive to Sunday and could return July 7 when the Orioles begin a two-game series in Washington.
"We're trying to get into a stretch and reel off a lot of wins, so that's the frustrating part, but these guys are going to pick me up and I'm going to pick them up when I get back," said Norris, who has been instructed to take five days off completely to let the groin heal.
"I want to do my job, I want to pitch every fifth day and win as many ballgames as I can and stay healthy. So I'm a little bummed out about it, but I've got to care of it and get back as soon as I can."
The Orioles recalled right-hander Evan Meek from Triple-A Norfolk to take Norris' spot on the 25-man roster. Meek is 0-2 with a 6.39 ERA in 12 2/3 innings over 13 appearances with the O's. The 31-year-old has gone 2-0 with a 2.79 ERA and three saves in 17 games for Norfolk.
While Meek joins the 25-man roster, the Orioles also officially called up right-hander Kevin Gausman from Norfolk to serve as the 26th player on the roster for Friday's doubleheader.
Gausman, who started Game 1 against Tampa Bay, has been excellent in four starts, going 3-1 with a 2.74 ERA and 1.17 WHIP. Per MLB rules, Gausman will return to Norfolk after Friday's second game of the doubleheader.
Ubaldo Jimenez could start Monday on regular rest in the opener of a four-game series against the Rangers.
Manager Buck Showalter suggested that Tuesday's start could go to right-hander T.J. McFarland, who is 0-1 in 13 relief appearances with a 2.81 ERA. Showalter said that the team may also look to Norfolk or Double-A Bowie for an emergency starter. He ruled out the possibility of Gausman starting on three days' rest.
"In June or [early] July, I wouldn't do that," Showalter said. "I don't think that's smart. It's not fair to him or to the team or to the fans. I think that would put him in harm's way.
"Right now, we're probably looking for a break in the weather… But we'll be all right. We've got some good options. That's where you were kind of hoping that a guy like Johan [Santana] would fit in. [Randy] Wolf isn't there yet."
