ST. PETERSBURG -- Yankees reliever Sergio Mitre had been battling a bacterial infection recently, but it was right shoulder tendinitis that had been ailing him most and perhaps led to a drop in velocity over his last few outings.
Because of that, Mitre was placed on the 15-day disabled list on Tuesday, with lefty Steve Garrison getting his first big league callup to likely be utilized in a long-relief role out of the Yankees' bullpen.
Manager Joe Girardi wasn't sure how long Mitre would be out, but the veteran right-hander had been getting treatment to address swelling in his right rotator cuff for a few days.
Reacquired from the Brewers on June 29, Mitre has given up nine runs (seven earned) in four appearances for the Yankees in a span of 5 1/3 innings and had lost some velocity and movement in recent appearances.
Garrison went 3-6 with a 6.26 ERA in 11 games (10 starts) for Double-A Trenton. The 24-year-old spent almost the entirety of Spring Training with the Yankees -- posting a 5.23 ERA in 10 1/3 innings -- and in that time, Girardi liked some things.
"I liked his ability to throw strikes," said Girardi, who now has a second lefty in the bullpen to go along with Boone Logan. "We put him in some tough situations, and he was able to throw strikes and throw his breaking ball behind in the count."
Garrison was originally a 10th-round Draft pick by the Brewers in 2005 who was traded to the Padres as part of the deal that landed Scott Linebrink in Milwaukee in July 2007, then was claimed off waivers by the Yankees last September.
Garrison was in Trenton, N.J., with his phone on silent on Tuesday morning, so he missed about seven calls from Trenton Thunder trainer Tim Lentych telling him he was getting called up. After finally picking up the phone, Garrison rushed to the airport in Philadelphia, caught a direct flight to Tampa International Airport and -- unlike Brandon Laird on Monday -- arrived with plenty of time to spare.
Now, after six-plus seasons in the Minors, Garrison can finally call himself a Major League player.
"I haven't stopped sweating since I woke up this morning; that may be a sign that it's starting to sink in a little bit," Garrison said. "It's definitely a great experience."
