Red Sox manager John Farrell said Tuesday that the team has no plans to shut down Koji Uehara.
Farrell acknowledged that with 134 1/3 regular-season innings pitched since the beginning of 2013 and an additional 13 2/3 frames in last year's playoffs, Uehara could be tiring. However, the closer hasn't reported any fatigue, so the club plans to keep going with him even though he's allowed seven earned runs over his last 3 1/3 innings. "He's gone through a bit of a stretch where he hasn't been as efficient or effective as we're accustomed to seeing," Farrell said. "But that does not take away our belief or confidence in him."

While he didn't give up any runs of his own, Koji Uehara blew another save after giving up a two-run double Monday against the Blue Jays.

With his splitter not splitting, it really looks like Uehara is all used up at the moment. Maybe 5-7 days off would cure him, but given that he's 39 and he's dealt with a much heavier than expected workload these last two years, it's also possible he's finished as an effective reliever, at least for 2014. His owners should probably grab Edward Mujica.

Koji Uehara suffered a complete meltdown Friday, allowing five runs while recording two outs in a blown save against the Mariners.

Uehara came close to getting out of it, but with two outs and the bases loaded he proceeded to give up a two-run double, two-run single and finally an RBI single that signified the end of his night. Not only was it the first time Uehara has ever given up five runs in an outing, he'd never even allowed four runs in a single appearance before Friday. He's now allowed seven runs over his last 2 2/3 innings, so it's certainly rough times for the 39-year-old right now.

Koji Uehara worked around a one-out single to pick up his 26th save as the Red Sox picked up a 3-2 win over the Reds on Tuesday.

Chris Heisey singled with one out, but Uehara induced a weak fly ball to right field and a pop-up to the catcher to end the ballgame. Uehara has put together 12 consecutive scoreless appearances. On the season, he has converted 26 of 28 save chances with a 1.29 ERA, 0.77 WHIP, and a 70/7 K/BB ratio.
Aug 12 - 11:14 PM

Koji Uehara struck out two in a scoreless inning of work to earn his 25th save of the season against the Angels on Sunday.

Uehara allowed a one-out single but didn't allow any more, striking out pinch-hitter Josh Hamilton to end the game. He's got 25 saves to go with a 1.32 ERA, 0.77 WHIP and 70/7 K/BB ratio in 54 2/3 innings this season.

Sean McAdam of reports that the Red Sox are unlikely to trade closer Koji Uehara.

The Red Sox are reportedly considering trading the likes of Jon Lester and Andrew Miller, but they apparently intend to make a qualifying offer to Uehara, who is an impending free agent. Because the qualifying offer will likely be in the area of one-year, $15 million this offseason, the thought is that he will accept. Of course, the Red Sox could trade Uehara and still re-sign him as a free agent, but there's the chance they would have to guarantee multiple years in order to do so.

Koji Uehara allowed a hit but recorded all three outs via strikeout to earn the save against the Rays on Sunday.

Uehara gave up a leadoff single to Yunel Escobar to start the ninth before fanning Sean Rodriguez, Curt Casali and Kevin Kiermaier to end it. The right-hander has now struck out 63 while walking just six in 47 2/3 innings of work. Uehara has 21 saves, a 1.51 ERA and 0.76 WHIP on the season.
Jul 27 - 5:29 PM

Nick Cafardo of the Boston Globe reports that Koji Uehara is "in great demand," but the Red Sox "would like to hold on to him."

The Red Sox are still seven games out in the Wild Card race and seem likely to be sellers at the trade deadline, but they apparently don't want to give up their closer. Uehara will be a free agent after the season and will turn 40 around Opening Day next year, but perhaps Boston will consider extending him or making him a qualifying offer this winter. He's been one of the best relievers in the game again in 2014, posting a 1.58 ERA and 59/6 K/BB ratio over 45 2/3 innings.
Jul 20 - 1:04 PM

Koji Uehara racked up his 19th save of the season on Friday, working a scoreless ninth inning to protect a one-run lead against the Royals.

The 39-year-old right-hander is in the midst of another unbelievable season, registering a 1.61 ERA, 0.76 WHIP and 58/6 K/BB ratio over his 44 2/3 innings, while converting 19 of his 21 save chances. As long as he remains healthy and on the field, he should continue to post elite numbers across the board.
Jul 19 - 12:50 AM

Koji Uehara will replace Masahiro Tanaka on the American League roster for the All-Star game.

Uehara is enjoying another fantastic year, owning a 1.30 ERA, 0.74 WHIP and 52/6 K/BB ratio over 41 2/3 innings. The right-hander also has 18 saves in 19 chances. Unbelievably, the All-Star selection is his first.
Jul 9 - 6:18 PM

FOX Sports' Ken Rosenthal reports that the Dodgers would be interested in a handful of Red Sox relievers should they be made available.

Rosenthal lists Koji Uehara, Andrew Miller, Burke Badenhop and Craig Breslow as potential targets. Uehara, Miller and Badenhop are all slated for free agency after the season, while Breslow has a $100,000 buyout attached to a $4 million club option for 2015.

Koji Uehara admitted after Tuesday's game that the cause of his recent struggles might be related to "a little bit of fatigue."

Uehara allowed a run in a tie game Tuesday to pick up the loss and has been scored upon in three of his last seven appearances, giving up three homers over that stretch. He hasn't really been overworked over the two-week period, but age could be a factor for the 39-year-old. "I probably need to get younger," Uehara joked. Ultimately, the closer should be fine. He still sports a ridiculous 1.40 ERA, 0.75 WHIP and 49/5 K/BB ratio over 38 2/3 frames this season.
Jul 2 - 9:02 AM

Koji Uehara took his second loss of the season, allowing a run in the ninth inning in Tuesday's defeat at the hands of the Cubs.

It's notable simply because Uehara has been so good. The closer has been more human lately, having allowed runs in three out of his last seven appearances. The Cubs put runners on second and third to lead off the ninth inning, allowing Luis Valbuena to plate a run with a sacrifice fly. Uehara's numbers are still great, though, as he has a 1.40 ERA, a 0.75 WHIP, and a 49/5 K/BB ratio over 38 2/3 innings.
Jul 1 - 11:06 PM

Koji Uehara worked a perfect ninth inning against the Yankees on Sunday, preserving a three-run lead and earning his 18th save of the season.

The 39-year-old hurler has once again been lights-out in the closer's role for the Red Sox, posting a 1.19 ERA, 0.72 WHIP and 48/5 K/BB ratio over 37 2/3 innings while converting all but one of his first 19 save chances.
Jun 30 - 12:17 AM

Koji Uehara suffered his first blown save of the season on Sunday, allowing two runs in the ninth inning of an extra-innings win over the A's.

Uehara gave up a solo shot to Stephen Vogt with one out and recorded a second out before John Jaso tied the game with his solo blast. Uehara has now allowed five runs all season, with all five coming on solo homers. The good news for Uehara owners is he ended up getting the victory out of the ordeal. Also good news is that he remains one of the most dominant relievers in the game, owning a 1.30 ERA, 0.72 WHIP and 44/4 K/BB ratio in 34 2/3 innings this year. All is still well.
