Gausman, Britton to appear for Norfolk on Sunday

BALTIMORE -- Kevin Gausman and Zach Britton, both optioned to Triple-A Norfolk following Tuesday's loss, will split Sunday's game to close their first half.

The team's decision to option the pair of pitchers on Tuesday makes them eligible to return the second game after the All-Star break if the O's have a need. In a non-injury situation, optioned players must remain in the Minors for at least 10 days.

Gausman pitched 1 2/3 innings after Britton's five-inning start, allowing two runs on two hits and a pair of walks. It was the first time in four relief outings the 22-year-old righty -- who made five starts earlier this year -- had allowed a run.

"Gaus has got a chance to be a quality Major League pitcher, and we all hope it's as a starter one day," said manager Buck Showalter, who said he was satisfied with what he saw in Gausman's second big league stint. "The only unknown that I really didn't get a feel for, and didn't want to, was back-to-back [games]. I got him up once, and when I got him up once ... all of a sudden, something happened where he didn't come in the game, I didn't get him up again. Really protective of that with him. I don't want to create something bad from something good.

"I think being in the bullpen was good for him, as he's talked to us about. He could come back to us in other ways. I hope there's not a need. He could certainly benefit from getting on a schedule down there, too."

Gausman is 1-3 with a 6.21 ERA in nine games for Baltimore this season, picking up the first win of his Major League career with 4 1/3 scoreless relief innings on June 28 against the Yankees.

Dickerson scratched with shoulder strain

BALTIMORE -- Chris Dickerson was a late scratch from Wednesday's lineup with a strained left shoulder. Nolan Reimold replaced Dickerson at designated hitter and hit a big three-run home run in the fourth.

It's uncertain how much time Dickerson will miss, and manager Buck Showalter said after Wednesday's win that they'd wait to see how he felt on Thursday. Dickerson said he has an MRI scheduled for Friday if necessary.

"Chris strained his left shoulder during batting practice and didn't like the way he felt afterward, and [we] decided it would be best to scratch him," Showalter said. "He's had some history of some challenges in that area. He's got some experience with it, so we'll see how it feels tomorrow. I'm hoping that it feels a lot better, but we're going to kind of lean on him because he's got a lot of experience with what it feels like when it's not right."

Dickerson said he had a problem with his left shoulder in 2004, and he's also had more serious troubles with his right shoulder.

"Hopefully, fingers crossed, it's not that bad," Dickerson said. "I'd like to say it's pretty simple, but you never know with rotator cuffs, they're pesky. We'll see what happens tomorrow. I'm just looking forward to getting past this, and hopefully it's quicker than expected and I can get back in the lineup."

Dickerson said he injured the shoulder on the last swing of his first round of batting practice. He added that he actually drove it out for a home run, but something didn't feel right after the swing.

"It was kind of like this radiating pain. I didn't really think anything of it besides 'Ouch,'" Dickerson said.

Dickerson took the next round off, but then finished up batting practice as usual.

"I finished BP, it wasn't anything that was debilitating as far as swinging the bat, but it was definitely painful," Dickerson said. "When it was warm, it wasn't that bad. But as it was iced, it definitely was stiffer and a little bit more painful. But it's a waiting game and we're going to remain positive about it. I'm not too worried about it as long as it's not a full tear like my right shoulder."

Orioles recall Stinson to support tired bullpen

BALTIMORE -- The Orioles recalled pitcher Josh Stinson from Triple-A Norfolk before Wednesday's game.

The right-hander, who was a starter at Norfolk, was brought up at least in part to provide a safety valve for lefty Wei-Yin Chen, who was activated from the disabled list Wednesday. Chen will start Wednesday's game. Manager Buck Showalter always likes to have a contingency plan in case a start is cut short, and Stinson should provide some innings in the bullpen if needed.

"We wanted to have some [bullpen] coverage tonight," Showalter said. "I don't think anybody can predict how Wei-Yin is going to feel physically. We want to make sure we're covered there."

The Orioles had room on the 25-man roster after they optioned Zach Britton and Kevin Gausman to Triple-A Norfolk following Tuesday's game.

Stinson, who went 4-4 with a 4.23 ERA in 15 starts, had not pitched for the Tides in three days and was scratched from his bullpen session Tuesday.

"I was [surprised]," Stinson said. "[Pitching coach] Mike Griffin came in [Tuesday] and told me not to throw my bullpen, so I thought something was up. It's definitely not expected."

How long he'll stay in the Majors isn't clear, and it could depend on how much the bullpen is needed for the next few days. The Orioles frequently shuffle pitchers between the big leagues and their affiliates to keep fresh arms in the bullpen, or even the rotation in some cases.

"I was told when I got claimed over here that they make a lot of moves. And I guess they had the most in Major League Baseball last year. So that was kind of expected," Stinson said. "But this many is surprising to me, because I was with Milwaukee last year and there really weren't that many moves. But it's an opportunity. I think every guy that comes up sees it as an opportunity to go up there and show them what you've got."

Though he was a starter in Norfolk, Stinson said he's comfortable coming out of the bullpen. For the whole 2009 season, half of '10 and half of '11, he was a reliever. Showalter said Triple-A manager Ron Johnson called Stinson one of his most durable relievers.

MLB announces winners of 'Tribute for Heroes' campaign

Camden Yards to host Casey Cares 5K Run/Walk

BALTIMORE -- The fourth annual Casey Cares 5K Run/Walk will take place at Camden Yards on Saturday, August 3, with the Orioles and OriolesREACH again partnering with the Casey Cares Foundation.

O's right fielder Nick Markakis and his wife, Christina, will serve as race ambassadors with Keith Mills, sports director of 98 Rock and WBAL Radio, the emcee.

The 3.1 mile run/walk starts at 8 a.m. ET, and it begins and ends at Oriole Park. Refreshments and a "Home Plate Finish" photo will be provided to each participant. Race winners in each age group will be announced in a pregame ceremony at the Orioles 7:05 p.m. game that night vs. the Seattle Mariners.

Registration for the race is open now through Aug. 3, and both teams and individuals are encouraged to register. Entry fees are $35 per person through Aug. 2 or $40 on race day. To register, visit www.caseycares5k.org.

"We are thrilled to partner with such a fantastic organization as the Orioles for our 5K," Casey Baynes, founder and executive director of the Casey Cares Foundation, said in the release. "While many Casey Cares children do their 'running' through the halls in the hospital, you can help support these critically ill children and their families by running or walking in our 5K."

All proceeds of the 5K will benefit the Casey Cares Foundation, a 501(c)(3) non-profit that provides personalized, uplifting and ongoing programs with a special touch to critically ill children and their family members throughout six states.

"Nick and I are so excited to be a part of the Casey Cares 5K," said Christina Markakis. "It is inspiring to see the brave, critically ill children and families that are helped through all of the Casey Cares Programs and awesome to see all the spirit come out of all the runners every year! We are thrilled to be a part of this special day and help make every day count for critically ill kids."

Worth noting

• Knuckleballer Eddie Gamboa, who was recently promoted to Triple-A Norfolk, made his first start for the Tides on Wednesday. Gamboa pitched 4 2/3 innings and gave up six runs (five earned). He struck out four batters and walked three.

While at Double-A Bowie, Gamboa narrowly missed a no-hitter and then completed a no-hitter.

•Steve Pearce had an MRA on his left wrist, which has been slower to heal than his right wrist. He was examined by Dr. Brian Schofield in Florida on Wednesday.

•Tsuyoshi Wada, who has pitched well in the Minors recently, was considered as a candidate for promotion Wednesday. He didn't get the call because the organization still considers him a starter, and Showalter prefers to have a right-handed long reliever follow a left-handed starter such as Chen if necessary.

• Top position-player prospect Jonathan Schoop (lower back) will start a rehab assignment on Thursday with the Orioles' Gulf Coast League affiliate. It's expected to last a week or more.

• Chris Dickerson was a late scratch from the lineup Wednesday. He was slated to start at designated hitter, and Nolan Reimold started in his place. The rationale for the late switch was not immediately clear.

• The Orioles have not announced a post-All-Star break starting rotation. Showalter said he'll wait for the dust to settle this week before making an announcement.
