SEATTLE -- The Orioles claimed Pedro Viola off waivers from the Reds on Wednesday, then optioned the left-hander to Triple-A Norfolk.
The 26-year-old Viola has nine games of Major League experience -- all registered with Cincinnati in 2009 -- and a 5.14 ERA in that seven-inning span. In '09, he also appeared in 54 games for Triple-A Louisville, going 2-2 with a 5.47 ERA and eight saves. This year, Viola, who was designated for assignment on April 11 -- has registered one shutout inning at Triple-A.
In order to clear room on their 40-man roster, the Orioles transferred outfielder Felix Pie from the 15-day to the 60-day disabled list. Pie is expected to miss three months because of a torn latissimus dorsi muscle.
Orioles call up Castillo to help out in 'pen
SEATTLE -- The Orioles continue to turn the organization's rosters around in search of talent, bringing up left-hander Alberto Castillo.
He replaced outfielder Felix Pie, who was placed on the 60-day disabled list with a ruptured latissimus dorsi muscle, the largest muscle in the back."I'm excited to be here again," Castillo said. "I'll do what I can to help the team. You're always excited to get the call. I'm ready for what ever they need me to do." The club has also signed former Orioles outfielder Corey Patterson to a Minor League contract. He will work get into shape at the club's Minor League complex in Sarasota, Fla. "He has been in this organization," manager Dave Trembley said. "With the unfortunate injury to Felix Pie, it gives us more insurance. We'll keep tabs on him." On Wednesday, the club claimed southpaw Pedro Viola off waivers from the Cincinnati Reds and optioned him to Triple-A Norfolk. Viola, 26, appeared in nine games for Cincinnati last season. He had a 5.14 ERA after working in 54 games for Triple-A Louisville, where he went 2-2 with eight saves and a 5.47 ERA. "He's a power left-hander," Trembley said. "He's a guy out of the 'pen, a guy who gives us another arm. There's a premium on those kind of guys." In order to make room for Viola on the 40-man roster, the Orioles transferred Pie from the 15-day disabled list to the 60-day disabled list.
Orioles ink Patterson to Minors deal
SEATTLE -- Veteran outfielder Corey Patterson has returned to the Orioles on a Minor League deal and will report to extended spring training on Thursday.
Patterson, 30, played for the Orioles in 2006 and '07, batting a combined .273 with 24 homers and 98 RBIs in 267 games in that span. He signed a Minor League deal with the Mariners in December, but opted out on March 31 upon being told he wouldn't make the team to start the season.
Last year, Patterson played in 113 combined games for the Triple-A affiliates of the Brewers and Nationals, batting .292 with 12 homers, 62 RBIs and 21 stolen bases. In 16 total games in the Majors for those clubs, he went 3-for-29.
Orioles left fielder Felix Pie is expected miss three months with a ruptured latissimus dorsi muscle -- the largest muscle in the back -- which created a need for another outfielder at Triple-A Norfolk, with Lou Montanez now in the Major Leagues.
For his 10-year career, the lefty-hitting Patterson has a .252 average with a .290 on-base percentage.
