Chen will start third game of season for O's

FORT MYERS Fla. -- Wei-Yin Chen will start the Orioles' third game of the season against the Boston Red Sox, manager Buck Showalter announced on Tuesday.

Chen will follow Opening Day starter Chris Tillman and Ubaldo Jimenez. Miguel Gonzalez and Bud Norris will start the fourth and fifth games in Detroit, although the order has not been decided.

Chen pitched on Monday in a Minor League game, and he's coming off a 2013 season in which he went 7-7 with a 4.07 ERA in 23 starts. He is 19-18 with a 4.04 ERA in 55 career games.

Catcher Clevenger, infielder Flaherty make roster

FORT MYERS Fla. -- The Orioles' roster continues to take shape, with manager Buck Showalter telling catcher Steve Clevenger and infielder Ryan Flaherty on Monday that they will exit camp with the team.

Both players were expected to make the team, with Flaherty likely at third base while Manny Machado is on the disabled list, and Clevenger serving as Matt Wieters' backup.

"I don't know if he's looked around yet, but there's no other catcher in camp," Showalter said of delivering the news to Clevenger. The O's manager also joked that part of the reason he told Flaherty was so he could stop "walking around on eggshells" in camp.

It will be the third Opening Day roster for both Clevenger -- who is from Baltimore -- and Flaherty. Clevenger's prior two were with the Chicago Cubs, and he's said all spring that he won't believe he's made the club until Monday's season opener against the Red Sox in Baltimore.

"Not yet. I'm going to play it out and wait until the end," Clevenger said. "At the end of the day, when my name is called on Opening Day I'll be on the team officially."

Orioles option reliever Brach to Triple-A

FORT MYERS Fla. -- The Orioles optioned right-handed reliever Brad Brach to Triple-A Norfolk on Tuesday night, putting their Spring Training roster at 40, including six non-roster players.

Brach, 27, had an impressive spring. He allowed two runs over 8 1/3 innings, striking out eight and allowing six hits and a walk over that span. Brach pitched a scoreless inning on Tuesday afternoon.

The Orioles acquired Brach from the San Diego Padres in November, in exchange for right-handed pitcher Devin Jones, after Brach was designated for assignment.

Worth noting

Michael Almanzar will be shut down for at least a few days after an MRI on his left knee revealed patella tendinitis on Monday. The Rule 5 Draft pick could possibly go on the disabled list, according to executive vice president of baseball operations Dan Duquette

Kelvin De La Cruz, who was designated for assignment on Saturday, has cleared waivers and been outrighted to Triple-A Norfolk.
