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.

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.

Justin Masterson was shelled in a loss to the Athletics on Tuesday, surrendering six runs in 2 1/3 innings.

Masterson found himself behind 3-0 after Stephen Vogt's two-run home run in the third and continued to bleed. He allowed a home run to Josh Reddick to lead off the third, then issued a one-out walk to Vogt before leaving. He gave up six hits in total along with the walk while striking out only one batter. Masterson has been dreadful on the mound thus far, as he carries a 6.37 ERA with a 1.67 WHIP and a 24/19 K/BB ratio in 35 1/3 innings. He'll vie for redemption in his next start, a road match with the Mariners.
May 13 - 1:05 AM

Justin Masterson gave up four runs and walked six in 4 1/3 innings Wednesday in a loss to the Rays.

Masterson had turned in three straight solid efforts, giving up six runs over 18 innings, but he completely lost the strike zone at times tonight and was lucky to last as long as he did. He and Joe Kelly are really neck-and-neck in the fierce competition to lose a spot in Boston's rotation.
May 6 - 10:40 PM

Justin Masterson took a no-decision Friday against the Yankees after allowing two runs over six-plus innings.

The final run scored after he issued a leadoff walk in the seventh inning and was pulled from the ballgame. Masterson gave up six hits and three walks while hitting a batter, so the Yankees had their fair share of chances, but he managed to minimize the damage for the most part. The 30-year-old owns a 4.71 ERA and a 22/12 K/BB ratio in 28 2/3 innings over his first five starts this season. He's not on the mixed league radar right now.
May 1 - 11:06 PM

Justin Masterson surrendered three runs in seven innings in Saturday's extra-innings loss to the Orioles.

This was one of Masterson's stronger starts of the season, though he did not come away with a decision. Jimmy Paredes had his number in the contest, hitting an RBI double and a solo home run, but Masterson was mostly able to limit the non-Paredes damage. Saturday's outing marked the first time that Masterson's pitched seven innings this season. He currently holds a lackluster 5.16 ERA and 1.32 WHIP in 22 2/3 innings pitched, but both of his last two starts have been solid and he's looked healthy thus far, which probably matters more than the early numbers. Masterson has a home date with the rival Yankees next time he takes the mound.
Apr 25 - 10:17 PM

Justin Masterson tossed five innings of one-run ball Monday as the Red Sox beat the Orioles in a rain-shortened game at Fenway Park.

Masterson held the O's to three hits and three walks while striking out five. The control is still a bit iffy for the 30-year-old right-hander, but he's 2-0 and his ERA fell Monday from 7.59 to 5.74. He'll try to remain undefeated in his next start on the road against this same Orioles team. Masterson looks healthier than he did in the second half last season with the Cardinals.
Apr 20 - 3:17 PM

Justin Masterson escaped with a no-decision, serving up seven runs in 4 1/3 innings as the Red Sox edged the Nationals 8-7 on Tuesday.

The Nationals jumped on Masterson in the fifth inning, putting up a six-spot, knocking him out of the game after recording just one out in the frame. Masterson, overall, gave up eight hits and three walks while striking out four. He's had mixed results over his first two starts but will try to rebound in his next start at home against the Orioles.
Apr 14 - 9:54 PM

Justin Masterson surrendered two runs and three hits in six innings Thursday in a win over the Phillies.

Masterson struck out seven. He also had two hits and an RBI at the plate, becoming the first Red Sox pitcher to do so since Josh Beckett in 2006. He'll have a home start against the Nationals next time out. He's only of use in AL-only leagues.
Apr 9 - 10:38 PM

Justin Masterson yielded two runs in five innings Saturday against the Twins.

Masterson didn't have the most encouraging of springs, and while he should be a decent enough bottom-of-the-rotation guy for Boston, it doesn't look like he'll be returning to 2013 form anytime soon. He ends Grapefruit League play with a 3.52 ERA and a 10/7 K/BB ratio in 23 innings.
Apr 4 - 3:43 PM

Justin Masterson held the Orioles to one run in four innings on Friday.

Masterson bounced back after getting lit up last time out by the Phillies (six runs in 3 1/3 innings), but his stuff is still down a tick. He's not looking like a mixed-league sleeper right now.
Mar 20 - 4:55 PM

Justin Masterson was pounded for six runs in 3 1/3 innings by the Phillies on Sunday.

After giving the Phillies a heaping helping of tasty, thigh-high fastballs, Masterson made it sound like he was more concerned about continuing to stretch his arm out than getting outs today. Hopefully, he'll become less generous as the spring progresses.
Mar 15 - 4:45 PM

Justin Masterson struck out four in three perfect innings as the Red Sox topped a Rays split-squad 5-1.

He also got four groundouts. We haven't gotten to see him yet, but Masterson's stuff is supposed to be better this spring after rib-cage and knee problems took a toll on his velocity last year. The Red Sox are counting on him as their fourth starter.
Mar 10 - 4:26 PM

According to Rob Bradford of WEEI, Justin Masterson turned down a one-year $6 million offer from the Rangers to sign with the Red Sox.

With the vast difference in the offers, it's not a surprise to see him wind up in Boston. He'll join a completely revamped Red Sox rotation that has added Wade Miley and Rick Porcello this week.
