FORT MYERS, Fla. -- The Twins scheduled a "B" game with the Red Sox that will be held at 1 p.m. ET on March 1 at Hammond Stadium, Twins general manager Terry Ryan announced Monday.

The Twins, who have 66 players in big league camp, including 33 pitchers, are also looking to add one more "B" game. The Twins open Grapefruit League play against the Rays on March 3.

"That'll help both of us," Ryan said of the "B" game with Boston. "They have more pitchers than we do; they have 34, we have 33. So it will help both of us. Then, if we can get another one scheduled maybe a few days after that, that'll lead us into the split-squad March 10 at Pittsburgh. That will take care of some of the concerns about making sure every one of these guys gets a fair shake."

The Twins also might play at least one intrasquad game, considering they have so many pitchers on their roster. But Twins manager Ron Gardenhire said the "B" game with the Red Sox is a good start.

"We're going to try to get nine innings out there," Gardenhire said. "We've got so much pitching, that'd be good. Probably one inning a piece, or two innings. The great thing about a 'B' game is you can roll innings over if a guy throws too many pitches. We can do whatever we want to."

Liriano throws first 'pen session of camp

FORT MYERS, Fla. -- A day after throwing off the mound, Twins left-hander Francisco Liriano threw his first bullpen session on Monday.

Liriano tossed more than 50 pitches -- throwing his fastball, slider and changeup -- and said he was throwing at about 80-85 percent.

"I just worked on my mechanics, staying tall, not getting too low," Liriano said. "Just working on that and trying to control my fastball, too."

Twins pitching coach Rick Anderson said staying tall in his delivery is the key to keeping Liriano consistent, as it forces him to pitch over the top and keeps his release point where it needs to be.

"If he stays tall from the start of his delivery, so he's throwing downhill, he's great," Anderson said. "And he'll be the first one to tell you, when he collapses, that forces him to jump out. I mean, there's times he's running to first base before he's throwing the ball, and that's because he's collapsing and getting out so far."

Blackburn has no restrictions this spring

FORT MYERS, Fla. -- Twins right-hander Nick Blackburn said he doesn't have any restrictions this spring despite undergoing surgery on Oct. 1 to decompress the radial nerve in his right forearm.

The surgery, which loosened up an inflamed nerve that was causing discomfort in his forearm, was done early enough in the offseason that it didn't affect his throwing program.

Blackburn said the rehab process went well, and that his forearm injury is a non-issue moving forward.

"From Day 1, Dr. [Thomas] Varecka told me once the surgery happened it wouldn't be an issue, and that's the way it's felt," Blackburn. "He said I might be weak rehabbing and my velocity might be down, but obviously at this point [in the year], my velocity is never up anyways. During the season it really isn't either, and right now I feel strong and good. I feel as healthy as I could coming into spring. So it's a good feeling."

Blackburn threw about a 10-minute bullpen session on Monday, and said everything went according to plan.

"I felt fine," Blackburn said. "I hadn't thrown a whole lot of curveballs to this point so that was kind of a little ugly. But they came out good; I was missing down, which is always good. They weren't all Frisbees out there. My mechanics were good and everything feels strong. I feel like I'm using my legs pretty good and getting good extension. That's all I could ask for right now."
