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.

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.
Jun 22 - 8:55 PM

Koji Uehara allowed his third solo homer and his third run of the season on Wednesday, but he ended up with the win against the Twins.

Chris Parmelee snuck one over the wall in right for the third run Uehara has given up in 32 2/3 innings. Since becoming a reliever, he's allowed 28 homers and 52 runs in 252 innings, which makes for a pretty incredible ratio.
Jun 18 - 4:38 PM

Koji Uehara picked up his 14th save of the season, working a scoreless ninth inning in Thursday's win over the Indians.

Two ground outs and a strikeout in what was yet another easy ninth inning for Uehara. The right-hander has now had 17 consecutive scoreless appearances, which has brought his ERA and WHIP down to 0.63 and 0.73, respectively. Uehara also has a 39/4 K/BB ratio and has yet to blow a save this season.
Jun 12 - 10:31 PM

Koji Uehara struck out two in a scoreless ninth inning to earn his 13th save against the Orioles on Tuesday.

Uehara allowed a single in his inning of work, but he worked around that -- and a dropped foul ball by catcher A.J. Pierzynski that gave Nick Markakis new life -- to fan Markakis and Manny Machado to end the game. The right-hander is enjoying another fabulous season, as he's now a perfect 13-for-13 in save opportunities with a 0.65 ERA, 0.76 WHIP and 38/4 K/BB ratio in 27 2/3 innings this year.
Jun 10 - 11:37 PM

Koji Uehara tossed a perfect ninth inning to pick up his 11th save of the season in Tuesday's win over the Braves.

Uehara struck out two in the process, giving him a 31/3 K/BB ratio in 20 2/3 innings this season. The right-hander hasn't allowed a run since May 1, giving him a streak of ten consecutive scoreless appearances. Uehara has an impressively congruent 0.87 ERA and 0.87 WHIP.
May 27 - 10:54 PM

Koji Uehara tossed a scoreless ninth inning Monday against the Braves for his 10th save of the season.

Uehara gave up a one-out single to Chris Johnson, but was able to induce a double play grounder from Andrelton Simmons to end the ballgame. In case you haven't noticed, the Red Sox haven't been winning many games recently, so this was his first save since May 11. He now has a 0.92 ERA and 29/3 K/BB ratio across 19 2/3 innings for the year.
May 26 - 6:49 PM

Koji Uehara struck out two in the ninth inning to earn the save against the Rangers on Sunday.

Uehara has nine saves without a blown save on the year. The right-hander appears to be fine after shoulder tightness hindered his performance near the end of April. Uehara has a 1.15 ERA, 1.02 WHIP and 24/3 K/BB ratio in 15 2/3 innings this season.
May 11 - 8:03 PM

Koji Uehara struck out all three batters he faced in the ninth Wednesday to earn the save in Boston's 3-2 win over Cincinnati.

It was Uehara's best outing since he returned from shoulder tightness last month. He was struggling terribly, with his ERA all of the way up to 1.32 going into the night. Tonight's perfect inning was his first since April 9.
