Red Sox president Dave Dombrowski said the club has moved on from free agent Koji Uehara.
Boston made an offer a few days ago, but Uehara wasn't ready to give an answer and the Tyler Thornburg addition now makes the veteran reliever unnecessary to the club's needs for 2017. Uehara turns 42 years old next April, but he did finish strong in 2016 and there should be a market for him if he wants to remain in the United States. Dec 6 - 4:43 PM

Koji Uehara will not be immediately available to pitch in back-to-back games.

Uehara was activated from the disabled list on September 5 following a layoff of almost two months due to a pectoral strain. The Red Sox aren't quite ready to pitch him in consecutive contests, but they expect the veteran reliever to be available for a heavier workload in about 10 days.
Sep 14 - 4:46 PM

Red Sox activated RHP Koji Uehara from the 15-day disabled list.

Uehara will be back in the Red Sox bullpen on Monday against the Padres after missing the last seven weeks with a pectoral strain. The veteran reliever holds a disappointing 4.50 ERA in 36 innings this season, but maybe the time off will help.
Sep 5 - 11:36 AM

Koji Uehara (pectoral) threw a live batting practice on Saturday.

Uehara allowed one hit over 25 pitches. He continued to throw on flat ground after BP concluded and looked "extremely confident," according to beat writer Pete Abraham of the Boston Globe. The team is hoping to activate him Monday when the Sox begin a three-game set against San Diego.
Sep 3 - 5:05 PM

Koji Uehara (pectoral) could be activated from the disabled list as soon as next Monday.

Great news for Uehara, who threw 20 pitches to hitters in a simulated workout on Monday. He still has two bullpen sessions coming up, but things are moving in the right direction. Uehara has been sidelined since July 20 with a pectoral strain, but his return would be a big boost to the back-end of Boston's bullpen.
Aug 29 - 4:46 PM

Koji Uehara (pectoral) faced hitters on the Fenway Park mound Monday afternoon in Boston.

Uehara threw around 20 pitches in the simulated workout. He appears to be nearing a return to the Red Sox bullpen after missing the last five weeks with a pectoral strain. The exact timetable hasn't been revealed.
Aug 29 - 3:45 PM

Koji Uehara (pectoral) threw 53 pitches off a mound on Friday.

ESPN's Scott Lauber noted that Uehara was throwing with "good intensity." Uehara is scheduled to throw again Monday and could face live hitters for the first time since straining his pectoral muscle shortly after the All-Star break. He'll likely share setup duties with Brad Ziegler upon his return.
Aug 27 - 6:31 PM

Koji Uehara (pectoral) threw a successful 32-pitch bullpen session on Tuesday.

He'll do similar workouts Friday and Monday before facing live hitters. Uehara has been on the disabled list since July 20 because of a pectoral strain. He could make it back to the majors around the middle of September if everything goes smoothly from here.
Aug 23 - 5:20 PM

Koji Uehara (pectoral) will throw off a mound on Tuesday.

It will be his first time doing so since landing on the disabled list with a pectoral strain about a month ago. The Red Sox have conceded that it's an unusual injury, but Uehara has a chance to make it back in September if he can avoid setbacks.
Aug 22 - 5:28 PM

Koji Uehara (pectoral) took part in long toss again on Wednesday.

Uehara was throwing from 150 feet out on Tuesday and did likewise on Wednesday. He has yet to begin throwing from the mound, a necessary step before he sets out on any rehab assignment. An early-to-mid September return could be in the cards here if he doesn't have any setbacks.
Aug 17 - 6:43 PM

Koji Uehara (pectoral) has extended his flat-ground throwing to 150 feet.

There's no date for his return to the mound, but it would seem to be drawing near. Uehara has been on the disabled list since July 20 with a pectoral strain. He could be back in the Red Sox bullpen sometime in early-to-mid September if all continues to go well.
Aug 16 - 5:23 PM

Koji Uehara (pectoral) has begun light throwing on flat ground at a distance of 60 feet.

It's small step in the right direction for the veteran reliever, who landed on the disabled list July 20 with a pectoral strain. The hope is Uehara will be able to return to the Red Sox bullpen before the conclusion of the regular season, but there are still many hurdles to clear and he can't push it too hard at age 41.
Aug 9 - 4:42 PM

Red Sox president of baseball operations Dave Dombrowski said Monday that there's no clear timetable for Koji Uehara's return from his strained right pectoral muscle.

"The injury is unusual. There’s not a lot of track record on this one," said Dombrowski. "So I do not have any idea. I know he’ll be out 15 days, but I can’t tell you if it’s going to be soon after that or long after that." Uehara suffered the injury last Tuesday and received a platelet-rich plasma on Friday to help with the healing process. The Red Sox are hopeful he'll be able to return this season, but his status is up in the air right now. The recently-acquired Brad Ziegler is filling in at closer right now, but Craig Kimbrel (knee) is expected to return next week.
Jul 26 - 9:22 AM

Red Sox manager John Farrell said Saturday that he is "hopeful" Koji Uehara (pectoral) can return this season.

Which of course means it's possible he will not return this season. Uehara was placed on the disabled list Wednesday with a strained pectoral, a unique injury for a pitcher. He got platelet-rich plasma treatment on Friday to try to expedite the healing. "There is no number of days that says Koji's going to put a ball back in his hand," Farrell told reporters Saturday. "He’s just getting past the soreness." Brad Ziegler is now serving as the primary closer in Boston with Craig Kimbrel (knee) also on the shelf.
Jul 23 - 4:49 PM

Koji Uehara (pectoral) has been given a platelet-rich plasma injection.

The hope is that it will help speed up the healing process with Uehara's right pectoral strain. At the moment, there's no timetable for the reliever's return.
