BALTIMORE -- The Orioles announced Thursday afternoon that left-handed pitcher Dana Eveland has cleared waivers and has been outrighted to Triple-A Norfolk.

Eveland was designated for assignment on March 29, when the club claimed infielder Zelous Wheeler off waivers from the Milwaukee Brewers. The 28-year-old Eveland was brought to Baltimore in a trade with the Los Angeles Dodgers for left-handed pitcher Jarret Martin and outfielder Tyler Henson at the Winter Meetings.

Eveland was 1-2 with a 3.46 ERA in six games (three starts) this spring and is expected to part of a Norfolk rotation that currently includes Brad Bergesen, Chris Tillman, Jason Berken, Armando Galarraga and Steve Johnson. It's possible one of those pitchers will be bumped to the bullpen or Double-A to make room for Eveland, with a six-man rotation another possibility.

Orioles could tweak rotation after first off-day

BALTIMORE -- The Orioles' rotation order for the first five games will be Jake Arrieta, Tommy Hunter, Jason Hammel, Brian Matusz and Wei-Yin Chen. But, according to manager Buck Showalter, that could change very soon.

"You may see us adjust that some after the off-day [on April 12]," said Showalter, whose club will need five starters to open the season and not again until April 20.

The club's first off-day is also the first day left-handed pitcher Tsuyoshi Wada is eligible to come off the disabled list. Wada is expected to compete for a starting rotation spot, along with lefty Zach Britton (shoulder impingement), who is in extended spring training.

Showalter said he doesn't put a lot of stock into the theory of separating the two lefties -- Matusz and Chen -- calling that idea overrated and citing the club wanting to give Chen as much rest as possible before he makes his first Major League start.

"If you can pitch, you can pitch, doesn't matter if you throw between your legs or with both arms, left, right, whatever," Showalter said.

"You don't get into saying, well you want this number of right-handers against this team and that team. It just fit best for us going forward, gave us the flexibility after the off-day to do some things if we need to. And if you understand some of the dates in which people are eligible to come back or not come back, it falls best for us."

Matusz will pitch the series opener against the New York Yankees on Monday, with Chen following on Tuesday.
