63 Justin Masterson SP

Masterson's agent, Randy Rowley, revealed Monday that his client has retired from professional baseball, Jon Heyman of FancredSports.com reports.

Masterson intends to turn his focus to missionary work after a big-league career that spanned eight seasons and featured stops in Boston, Cleveland and St. Louis. The soft-tossing right-hander, who went 64-74 with a 4.31 ERA across 258 games, most recently appeared in affiliated ball in 2017 as a member of the Dodgers' Triple-A squad.

Masterson has signed a minor-league deal with the Dodgers, Jon Heyman of FanRag Sports reports.

Masterson missed the entirety of the 2016 season with shoulder issues, but he's been successful enough over an eight-year career to draw consistent interest this winter. Although Masterson is unlikely to open the season with the Dodgers, he'll serve as important depth for a rotation with many injury-prone pitchers. Masterson has also expressed a willingness to pitch out of the bullpen, so we'll keep an eye on how the Dodgers intend to deploy him.

Masterson threw a live batting practice session in Reds camp Thursday, Mark Sheldon of MLB.com reports.

The right-hander did not appear in the majors in 2016, but he does hold lots of experience over his eight other seasons in the major leagues. That's a huge boon to his value given the inexperience in the Reds' current pitching staff, although he'll have to improve upon the 4.97 ERA he posted in 20 relief appearances and five starts with the Pirates' Triple-A affiliate last season if he wants to be in the conversation for a big league spot. It's unclear how close the two sides are to a deal, but the Reds have stated that any agreement with Masterson would be on a minor league deal.

Masterson will throw two showcases over the next week, ESPN's Jerry Crasnick reports.

According to Crasnick, roughly 12 teams will be in attendance for Masterson's showcases in Arizona. He has been hampered by shoulder issues of late, but he did manage to pitch in 50 minor league games across two levels in the Pirates' organization in 2016. Masterson's agent said that he is willing to work as either a starter or a reliever, and that the right-hander is 100 percent healthy.

Masterson (shoulder) will begin a throwing program in Arizona next week and plans to hold a showcase for potential suitors in late February, Paul Hoynes of Cleveland.com reports.

Masterson, a former All-Star, spent last season in the Pirates' organization, posting a 4.97 ERA and a 32:26 K:BB ratio over 25 games with Triple-A Indianapolis. It appears the 31-year-old is ready to give his career another chance after electing free agency in November. Masterson's velocity has clearly fallen off since his dominant 2013 season, when he led the MLB in shutout victories. Consider him a long shot to make a roster at this point.

Masterson (shoulder) has been transferred to Triple-A Indianapolis, where he is scheduled to make two starts before the Pirates make a decision on whether to recall him, Jon Heyman of MLB Network reports.

Masterson's shoulder issues appear to be behind him and he is set to face stiffer competition up at Triple-A Indianapolis. He'll make at least two starts, and if he's able to get through them without any issues, he could be on his way back to the major leagues. In his lone start at High-A Bradenton, Masterson allowed two runs over five innings while racking up eight strikeouts and three walks.

Masterson (shoulder) continues to make progress while pitching in extended spring training. "It's just a matter of trying to build him up and continuing to try to build some arm strength, as well as continuing to take steps forward to allow him to repeat his mechanics," GM Neal Huntington told the Pittsburgh Tribune-Review. "But so far, so good."

Huntington said Masterson gradually has stretched out his outings to four innings, while his velocity has increased as well. The righty struggled in 2015, compiling a 5.61 ERA and 1.60 WHIP in 59.1 innings before undergoing arthroscopic shoulder surgery in September.

Masterson (shoulder) agreed to a minor league deal with the Pirates on Thursday, Jon Heyman of MLB Network reports.

Masterson held a showcase in late March for teams to demonstrate that he had recovered from shoulder surgery in September. He impressed the Pirates organization enough for them to take a minor league flier on him, but there's no word on which affiliate he'll be assigned to at this point. The Pirates' rotation appears to be cemented at the major league level, but Masterson could potentially be called up later in the season to eat up some innings out of the bullpen.

Masterson (shoulder) plans on throwing at a showcase in late March, Chris Cotillo of SB Nation reports.

The veteran right-hander has bounced around several different organizations since his All-Star season with the Indians in 2013 and was most recently with the Red Sox last season before being released in August. He is attempting to make a comeback after undergoing shoulder surgery in September and, according to Cotillo, Masterson will have plenty of interested parties at his showcase. Still, even if he lands a deal with a major league club, there isn't a particularly high fantasy ceiling for a 31-year-old pitcher that is coming off multiple injury-shortened seasons.

Veteran right-hander Justin Masterson has been designated for assignment by the Red Sox, the Boston Globe has reported.

The sidearming right-hander has been a bust in his return to Boston and has struggled since 2013. He spent six weeks on the disabled list, lost his spot in the rotation in early July, and has compiled a 4-2 record and 5.55 ERA on the year.

The 30-year-old Masterson has been particularly bad lately. He has allowed six runs on 13 hits and five walks in his last 10 1/3 innings.

Red Sox starting pitcher Justin Masterson is not a candidate to rejoin the rotation after the All-Star break, according to the Boston Herald.

Masterson (3-2) has been unimpressive this season. He has a 6.14 ERA with 32 strikeouts and 21 walks in 45 innings of work.

Red Sox pitcher Justin Masterson will be used out of the bullpen through the All-Star break, reports WEEI.com.

Masterson is 3-2 with a 6.14 ERA on the season. He allowed five runs in 3 2/3 innings in his last start.

Red Sox starter Justin Masterson was knocked out of the box by Houston after 3 2/3 innings, but he escaped with a no-decision as Boston batters rallied later in the game. 

Masterson gave up five runs on eight hits, his second early knockout in three starts. He gave up six runs in 2 1/3 on May 12 and has a 9.00 ERA in his last three starts. 

Red Sox manager John Farrell confirmed Monday starting pitcher Justin Masterson will be back on the hill Friday against the Astros after throwing five strong innings in a 5-3 win Sunday at Tampa Bay. Masterson allowed one unearned run on five hits and no walks, while striking out six.

Masterson is replacing Joe Kelly in the rotation after Kelly was optioned to Triple-A Pawtucket last week.

Red Sox starting pitcher Justin Masterson was very impressive in Sunday's matchup against the Rays.

Masterson threw five innings, allowed just five hits and one earned run before being pulled from the game. He struck out six batters while picking up his third win of the season.

Masterson (3-2) lowered his ERA to 5.58 with the performance.

With the Red Sox optioning starting pitcher Joe Kelly to Triple-A Pawtucket on Thursday, the team announced Justin Masterson would replace him in the rotation Sunday against the Rays.

Masterson was activated off the disabled list Tuesday. He was moved to the bullpen, but he did not make any relief appearances. He is 2-2 with a 6.37 ERA in seven starts this season.

Red Sox right-hander Justin Masterson is active again, but has been moved to a rather unfamiliar place. He has been sent to the bullpen. He has pitched just 12 games in relief since 2009.

Masterson is off the disabled list after missing six weeks with a shoulder injury, per the Boston Globe. But his miserable performance before going down has motivated John Farrell to kick him out of the starting rotation.

The sidearmer returns with a 2-2 record and 6.37 ERA. Most concerning is that he has walked 88 batters over the last 164 innings going back to 2014.

Red Sox pitcher Justin Masterson threw a bullpen session on Sunday, which he said likely means that his rehab start, scheduled for Monday, is probably off, per the Boston Herald.

Masterson is on the DL with a shoulder injury. The team wasn't sure whether to leave him in the minors for another start or work toward bringing him back to the Red Sox bullpen.

Masterson will likely throw another bullpen on Tuesday as he nears a return to the Red Sox. 

Red Sox starting pitcher Justin Masterson is not sure what the next step following his recovery from a shoulder injury will be, per the Providence Journal.

Masterson said the Red Sox have yet to make a decision on whether he will rejoin the team out of the bullpen or participate in another minor-league rehab start. The team could have Masterson go through another rehab start because the rotation is currently very condensed.

"What I’d ultimately like to do and what would be great for all is to go start, but guys have been doing great and that’s understandable that that’s not open at this point in time," Masterson said. "I don't know if it’s in my nature to say, ‘Beat it guys, trade me or put me in here.’ No, I don't think that’s the time right now. Especially the way I see this team going and the way I believe in this team too. I’d like to be a part of it in some way, shape or form."

When he does return to the Red Sox, Masterson could be utilized out of the bullpen, which is a spot he hasn't been in consistently since 2009.

"Right now I feel comfortable pitching in general," he said. "You put me in the pen when you have a good comfortability of what you’re doing, it’s not too bad. Having been there before does help out."

Red Sox pitcher Justin Masterson, who is on a rehab assignment with Triple-A Pawtucket, has proven he is ready to return to the roster, manager John Farrell told reporters Wednesday.

However, the team is still determining if Masterson (shoulder) will rejoin the rotation or be placed in a relief role. Farrell said Masterson is open to pitching out of the bullpen.

The right-hander is 2-2 with a 6.37 ERA in seven starts this season. He is 0-2 with a 3.44 ERA in four rehab appearances between Double-A and Triple-A.
