Justin Masterson may throw for teams in mid-March, per Chris Cotillo of MLB Daily Dish.
Cotillo reports that Masterson has drawn interest from "several teams," but he's just starting his throwing program this week and is apparently content with waiting out the process before signing with a team. The veteran right-hander posted an ugly 5.61 ERA over 59 1/3 innings with the Red Sox last season before undergoing undergoing arthroscopic surgery on his shoulder in September. Jan 27 - 11:57 AM

Chris Cotillo of MLB Daily Dish reports that two teams have made offers to free agent right-hander Justin Masterson.

Meanwhile, Cotillo hears from his source that 10 teams have requested medicals. Masterson posted an ugly 5.61 ERA over 59 1/3 innings for the Red Sox last season before undergoing arthroscopic surgery on his right shoulder in September, but he's not far removed from success and could have some appeal if he's feeling good. The Pirates were mentioned as a possible fit last month.
Jan 6 - 1:26 PM

CBS Sports' Jon Heyman reports that five teams are in on Justin Masterson.

The Pirates are one of them, which had been previously reported. Masterson held an ugly 5.61 over 59 1/3 innings for the Red Sox in 2015 and had arthroscopic right shoulder surgery in September. He could be a nice bounce-back candidate in the right spot, though, and Pittsburgh would certainly qualify.

Travis Sawchik of the Pittsburgh Tribune-Review reports that the Pirates are interested in Justin Masterson.

Masterson is looking for a one-year deal in hopes of rebuilding his value, and there's wouldn't be a better landing spot than Pittsburgh, where he could work with pitching guru Ray Searage. Slated to turn 31 in March, Masterson held an ugly 5.61 over 59 1/3 innings for the Red Sox in 2015 and had arthroscopic right shoulder surgery in September. He's expected to be healthy for spring training.

Justin Masterson underwent successful arthroscopic right shoulder surgery on Wednesday.

He's expected to be fully healthy by the start of spring. The 30-year-old will be a free agent this winter after being released by the Red Sox in August, and he'll likely have to settle for an incentive-laden deal to re-establish value.

Red Sox released RHP Justin Masterson.

Masterson's signing is one of the reasons former general manager Ben Cherington was pushed out the door and the righty's release is technically new president Dave Dombrowski's first move. He should be able to latch on elsewhere now that he can be had on the cheap.

Red Sox designated RHP Justin Masterson for assignment.

The 30-year-old right-hander allowed a solo home run in his inning of work on Sunday, bringing his ERA to 5.61 over 59 1/3 innings on the season. He could generate some interest on waivers from team's in desperate need of rotation depth.

Red Sox manager John Farrell confirmed Thursday that Justin Masterson will remain in the bullpen to begin the second half of the season.

Brian Johnson will take the place of the injured Clay Buchholz for the time being and will work on either Monday or Tuesday, with the other day's starter still to be determined. Masterson will continue to try to work through his troubles in long relief or mop up duty.

Justin Masterson will pitch out of the bullpen for the remainder of the first half.

The Red Sox don't need a fifth starter during the remaining week. With Masterson being used in relief, Wade Miley will move up to pitch Tuesday and Rick Porcello will take the ball Wednesday.

Justin Masterson unraveled in the fourth inning of Friday's loss to the Astros, allowing all five runs on his line before exiting with two outs in the frame.

Masterson was cruising through the first three innings, but the cruise hit a whirlpool in the fourth when Masterson allowed seven hits and five runs in the frame. There was no huge hit, just a parade of singles and doubles. With the debacle, Masterson saw his ERA jump from an already poor 5.58 to an even more questionable 6.14. He's also pitching to a 1.68 WHIP. Given that he just reentered the rotation on June 28, it's likely he'll get at least one more start, but the numbers are discouraging. Said start would come in a high-profile environment, as the Red Sox will be facing the Yankees at Fenway when Masterson's next slated to take the ball.

Justin Masterson, making his first start since May 12, held the Rays to one unearned run in five innings en route to a win on Sunday.

Masterson is taking the rotation spot of Joe Kelly and pitched well enough to warrant that decision, scattering five hits with no walks and six strikeouts. The lone run came across in the fifth, helped in part by a passed ball from catcher Blake Swihart. In eight starts overall this season, Masterson has a 5.58 ERA, a 1.59 WHIP, and a 30/19 K/BB ratio in 40 1/3 innings. He'll start against the Astros at home next weekend.

Justin Masterson will start for the Red Sox on Sunday afternoon against the Rays.

He is taking over for Joe Kelly, who was demoted to Triple-A Pawtucket on Thursday morning. Masterson has an ugly 6.37 ERA and 1.67 WHIP in 35 1/3 innings this season for the Red Sox. He is a bad fantasy option.

Red Sox activated RHP Justin Masterson from the 15-day disabled list.

Masterson will join the Boston bullpen on Tuesday night after missing five weeks with tendinitis in his right shoulder. He'll likely operate in a long relief role.

Justin Masterson (shoulder) is expected to rejoin the Red Sox on Tuesday in a relief role.

That there's no room for him in the club's rotation despite numerous arms struggling doesn't say much for Masterson. He held a 6.37 ERA over seven starts before going on the disabled list with a phantom shoulder ailment.
Sun, Jun 21, 2015 12:39:00 PM

Justin Masterson could return to the Red Sox in a bullpen role.

"I think he's proved he's ready to come back," Red Sox manager John Farrell said. "It depends on what role we put him in. ... We haven't ruled out the possibility of that being in the bullpen." Masterson has made four rehab starts in the minors and will likely be promoted in the coming days.
