Date:

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.
Jul 5 - 11:36 AM

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.
Jul 3 - 11:51 PM

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.
Jun 28 - 4:35 PM

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.
Jun 25 - 11:29 AM

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.
Jun 23 - 4:36 PM

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.
Jun 21 - 12:39 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.
Jun 17 - 8:18 PM

Justin Masterson (shoulder) will make another rehab start with Triple-A Pawtucket on Tuesday.

It will be the fourth rehab start for the right-hander. Joe Kelly has pitched better of late, so it's possible Masterson will return as a reliever.
Jun 14 - 2:39 PM

Justin Masterson (shoulder) will make another rehab start with Triple-A Pawtucket on Wednesday.

The Red Sox had been considering bringing him back after he allowed two runs over 4 2/3 innings Friday, but they'll give him another outing. It's not out of the question that Masterson returns as a reliever.
Jun 7 - 11:36 AM

Justin Masterson (shoulder) could be cleared to rejoin the Red Sox rotation without requiring another minor league rehab start.

No decision will be made until he completes his side session on Sunday, but he could be ready to jump back into the rotation next week. It's unclear who he will supplant in the Red Sox rotation, but Joe Kelly seems like a strong possibility.
Jun 6 - 1:43 PM

Justin Masterson (shoulder) is scheduled to make his first minor league rehab start with Triple-A Pawtucket on Sunday.

He'll work three innings in the ballgame. The veteran right-hander has been working with new pitching coach Carl Willis while rehabbing in recent weeks, so it will be interesting to see how he performs once he's able to rejoin the Red Sox rotation.
May 28 - 6:15 PM

Justin Masterson (shoulder) did some light throwing in the outfield prior to Friday's game.

Masterson hit the disabled list on Thursday with tendinitis in his right shoulder, but it's good to see that he's still throwing. He was working on his mechanics during the session with new pitching coach Carl Willis. There remains no clear timetable for his return to the Red Sox rotation.

May 16 - 9:29 AM

Red Sox placed RHP Justin Masterson on the 15-day disabled list with right shoulder tendinitis.

It's a phantom injury designed to get Masterson out of the rotation for a bit. He'll get some rest and then begin working on his stuff at one of the club's minor league affiliates -- likely Triple-A Pawtucket. Masterson had registered an awful 6.37 ERA and 1.67 WHIP in 35 1/3 innings (seven starts) this season for Boston.
May 14 - 2:21 PM

The Red Sox will place Justin Masterson on the disabled list with what manager John Farrell referred to as "arm fatigue."

It looks like a phantom injury, as Masterson insisted after another poor performance Tuesday that he was fine physically. Regardless of the legitimacy of the "injury," the right-hander figures to stay away for a while as he tries to get things back in order. Steven Wright is expected to start on Sunday against the Mariners.
