Koji Uehara issued his first walk since last Aug. 5, but he struck out the other three Orioles he faced for a save Saturday.
Uehara went his last 23 regular-season innings, 13 2/3 postseason innings and then six innings this year without walking a batter before throwing ball four to Matt Wieters today. His current 11/1 K/BB ratio this season is actually worse than his mark from last year (101/9) or 2012 (43/3). Apr 19 - 4:46 PM

Koji Uehara earned a save with a scoreless ninth in his return to the mound Thursday against the White Sox.

Uehara showed his usual velocity in his return from a sore shoulder, but he did give up a single and miss up with a couple of splitters to a dangerous hitter in Jose Abreu with two outs. Fortunately, Abreu didn't take a cut at either of those before grounding out on a better offering. In all, Uehara threw 13 pitches. The Red Sox will likely be especially careful with him for the next few weeks, so if they have another save situation on Friday, we imagine it will go to Edward Mujica.

Koji Uehara (shoulder) threw a 34-pitch bullpen session Wednesday and came out of it fine.

It was the last real hurdle before the right-hander returns to action for the Red Sox. He won't be available for Wednesday's game after throwing so many pitches in the bullpen, but he'll be ready for use for Thursday. It's assumed, then, that he'll also be ready to roll if a save opportunity arises.
Apr 16 - 6:17 PM

Koji Uehara (shoulder) is on track to be available out of the Red Sox' bullpen on Thursday.

Uehara long-tossed again Tuesday with greater intensity and is slated to throw a bullpen session Wednesday. He should immediately regain his closer duties, but Edward Mujica would be used if save situations came up Tuesday and/or Wednesday.
Apr 15 - 6:21 PM

Tests on Koji Uehara's right shoulder have confirmed that he has no structural damage.

The Red Sox suspected that the MRI would be clean, as Uehara was able to get through a throwing session Sunday with no issues. He'll rejoin the Red Sox on Tuesday in Chicago, though it's not clear whether he'll be available to pitch immediately. Edward Mujica could still see the next save chance or two.
Apr 14 - 8:16 PM

Koji Uehara (shoulder) is expected to rejoin the Red Sox on Tuesday after undergoing further tests in Boston on Monday.

The Red Sox were pleased with his throwing session on Sunday and Uehara noted that he felt better than expected. There is growing optimism that he'll be able to avoid a trip to the disabled list.
Apr 13 - 6:12 PM

Koji Uehara (shoulder) was able to play catch and throw some pitches off flat ground on Sunday without any issues.

Uehara appeared to be working at normal effort. It doesn't sound like the Red Sox will make a decision on him until after he undergoes further testing in Boston on Monday. Should he require a trip to the disabled list, Edward Mujica would be the most likely to handle save chances in his absence.
Apr 13 - 5:40 PM

Koji Uehara (shoulder) will attempt to long toss on Sunday, but could inevitably return to Boston for further tests on Monday.

The Red Sox are still gathering information on his situation, but it's starting to look like a trip to the disabled list could be a very realistic possibility. Edward Mujica should be snatched up in all fantasy leagues where he's available.
Apr 12 - 11:38 AM

Red Sox manager John Farrell said he'll likely stay away from using Koji Uehara on Saturday and then see how he feels on Sunday.

The Red Sox are holding out hope that the issue is minor and that Uehara will be able to resume his closing duties on Sunday. If he's unable to do so and requires a trip to the disabled list, Edward Mujica would get the ball in the ninth inning in his stead.
Apr 12 - 10:38 AM

Koji Uehara is considered day-to-day with minor stiffness in his right shoulder.

The 39-year-old right-hander said that the injury is similar to what he felt two years ago in Texas, an injury that lingered for several months. Edward Mujica picked up a save in his absence on Saturday and could be worth a look as a speculative add in mixed leagues until Uehara returns to the mound.
Apr 12 - 8:42 AM

Koji Uehara wasn't used in a save situation in Friday's win over the Yankees as he's dealing with minor stiffness in his shoulder.

Red Sox manager John Farrell said that it was merely precautionary, but it's certainly something fantasy owners should keep an eye on. Edward Mujica got the call instead and worked as scoreless ninth inning to convert his first save as a member of the Red Sox.
Apr 11 - 10:32 PM

Red Sox general manager Ben Cherington confirmed Saturday that Koji Uehara will begin the 2014 season as the team's closer.

It's no surprise considering the 38-year-old is coming off one of the most dominant reliever seasons in major league history, posting a 1.09 ERA, 0.57 WHIP and unbelievable 101/9 K/BB ratio over 74 1/3 innings. Cherington also noted that he "would love to have more than one closer on the team," referring to the recently-signed Edward Mujica who should be considered as a handcuff to Uehara in fantasy drafts.

Koji Uehara closed the door on the Cardinals in Game 4 of the World Series on Sunday, preserving a two-run advantage and evening the series at two games apiece.

The 38-year-old right-hander allowed a one-out single to pinch-hitter Allen Craig, then retired Matt Carpenter and astonishingly picked off pinch-runner Kolten Wong to end the game. He’s now racked up six saves this postseason while compiling a 0.79 ERA, 0.62 WHIP and 13/0 K/BB ratio in 11 1/3 innings.

Red Sox skipper John Farrell said Sunday that Koji Uehara is available for more than an inning of work if necessary during Game 4 of the World Series.

Uehara worked just 1/3 of an inning in the Red Sox loss to the Cardinals on Saturday, and Farrell won't hesitate to utilize his best reliever for more than three outs in a near must-win game on Sunday. After compiling one of the best regular seasons of any reliever in Major League history, Uehara has posted a miniscule 0.87 ERA, 0.58 WHIP and 13/0 K/BB ratio through 10 1/3 innings in the postseason.

Koji Uehara once again slammed the door on the Tigers in the ninth inning on Saturday, and afterwards was named ALCS MVP for his dominance in the series.

Uehara surrendered a two-out single to Austin Jackson on Saturday, but that was the extent of the damage against him as he fanned a pair in another scoreless inning of work. For the series, Uehara appeared in five games, firing six scoreless innings of relief, fanning nine, walking none and allowing just four hits. He's the first relief pitcher to earn the award since Mariano Rivera in 2003. He'll look to continue his magical 2013 season against the Cardinals in the World Series.
