LAKELAND, Fla. -- It's been an interesting 12 months for Donnie Hart. A year ago, he was an unknown left-hander in Orioles Minor League camp. This year, he's expected to play a big role in the big league bullpen.
Hart was having a great year in Double-A Bowie and impressed in three July appearances with the Orioles. He came back to the Majors in mid-August and gave up his only earned run in his 19th big league appearance, ending the season with an 0.49 ERA in 22 games.

Red Sox first baseman Hanley Ramirez homered against Hart at Camden Yards on Sept. 22.
"I don't think there's a whole lot from a number side of it that I can do better than what I did last year," Hart said.
"It's one of those things where I'm going to have to take the same approach and stick with it. There's going to be times where I will have success, but mentally, it's one of those things where you just have to kind of stick to what you've been doing and if something goes wrong, take a step back and kind of be open-minded and have ears and listen and take advice."
Hart and Zach Britton have some new left-handed company in the Orioles' clubhouse. In the past several days, the Orioles have added left-handers Richard Bleier and Vidal Nuno to the team.
"We haven't had a whole lot of lefties in the past. It's a good thing. If anything it will push you and drive you and make you do your job," Hart said. "That wasn't one thing that I was going to sit back and say, 'Oh, they don't have any lefties here, so I don't have anything to worry about.'
"That's not the right mindset. That wasn't my mindset. It's always fun to have lefties around because there are more brains to talk to."
