Koji Uehara notched his seventh save of the season Wednesday in Boston's win over the A's.
Uehara issued a two-out walk to Stephen Vogt but promptly induced a game-ending groundout from Eric Sogard. There was quite a bit of concern about the 40-year-old Uehara entering the 2015 regular season, but he boasts a 1.80 ERA, 0.70 WHIP, and 13/2 K/BB ratio in 10 innings. And he's converted seven of his eight save opportunities. May 13 - 6:22 PM

Koji Uehara earned his sixth save of the season on Sunday, pitching a scoreless ninth inning as the Red Sox won 6-3 against the Blue Jays.

Uehara got two quick outs, striking out Chris Colabello and getting pinch-hitter Danny Valencia to ground out. He then issued a walk to Josh Thole but got Justin Smoak to ground out to end the game. The veteran right-hander has converted six of seven save opportunities with a 2.16 ERA and a 12/1 K/BB ratio in 8 1/3 innings.
May 10 - 4:01 PM

Koji Uehara retired the Rays in order to pick up his fifth save, closing out a 2-0 win versus the Rays on Tuesday.

Protecting a two-run lead, Uehara kept David DeJesus, Logan Forsythe, and Asdrubal Cabrera in the infield for a 1-2-3, 13-pitch ninth inning. He's 5-for-6 in save situations now with a 2.45 ERA, 0.68 WHIP, and 11/0 K/BB ratio in 7 1/3 innings.
May 5 - 10:12 PM

Koji Uehara fanned all three batters he faced to earn a save Wednesday against the Blue Jays.

Uehara's velocity was the best of the year tonight, and he's throwing more fastballs now that it has crept back up. He could always get hurt again at some point, but he's back looking like a fine fantasy closer for now.

Koji Uehara pitched a scoreless ninth inning against the Rays to earn his second save of the season Tuesday.

Uehara gave up a leadoff single to Logan Forsythe but quickly erased him with a double play from Evan Longoria. Uehara retired Desmond Jennings to close out the one-run victory. The right-hander hasn't been scored upon in three innings, and Forsythe's single is the first baserunner he's allowed. A hamstring injury behind him, the 40-year-old appears to be back in top form.
Apr 21 - 10:05 PM

Koji Uehara, making his season debut, retired the Nationals in order in the ninth inning for his first save.

Uehara was activated from the disabled list on Monday, having healed from a hamstring injury suffered in March. He had no issues carving through the middle of the Nationals' lineup. He struck out Bryce Harper, got Ryan Zimmerman to line out, and fanned Clint Robinson to end the contest. Uehara will resume getting almost all of the save chances, which leaves Edward Mujica without much fantasy value now.
Apr 14 - 9:46 PM

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

Uehara had been sidelined with a hamstring injury suffered during spring training. The veteran closer experienced no setbacks in his rehab. He'll take back his normal ninth inning spot from Edward Mujica, who will move to a setup role.
Apr 13 - 12:46 PM

Red Sox manager John Farrell confirmed Sunday that Koji Uehara (hamstring) is likely to be activated from the disabled list on Monday.

The veteran right-hander is working his way back from a strained hamstring. He's expected to immediately regain his closer role, relegating Edward Mujica back to a setup role.
Apr 12 - 6:02 PM

Koji Uehara (hamstring) will make a minor league rehab appearance Saturday with Class A Greenville.

In other words, everything is going according to plan as Uehara makes his way back from a hamstring strain. He might only need one appearance, so he should be activated for the home opener on Monday. Edward Mujica will continue to fill in for now.
Apr 9 - 5:05 PM

Koji Uehara (hamstring) threw 30 pitches Tuesday in a simulated game.

It was essentially an extended batting practice session. He's scheduled to throw another simulated game Thursday before making a minor league rehab appearance with Class A Greenville on Saturday. Barring any setbacks, he should be activated for the home opener on April 13. Edward Mujica will get the chance to fill in for a few days.
Apr 7 - 12:55 PM

Koji Uehara (hamstring) is scheduled to throw a simulated game on Thursday.

If all goes well, he will go out on a minor league rehab appearance on Saturday. The goal if he makes it through those sessions healthy, will be to activate him for the home opener on April 13. Edward Mujica will see the bulk of the save chances in his absence.
Apr 4 - 3:39 PM

Red Sox placed RHP Koji Uehara on the 15-day disabled list, retroactive to March 27, with a left hamstring strain.

The hope is that he'll be ready to go when first eligible on April 11, but Uehara admitted earlier this week to still feeling pain when he tried throwing from a mound. Edward Mujica will be the Red Sox' primary closer while Uehara is on the shelf.
Apr 3 - 3:39 PM

Koji Uehara said his ailing left hamstring felt the "same as last time" when he tried to throw a bullpen session Monday.

Uehara hasn't pitched in a game since March 14 and remains unable to throw at 100 percent effort off a mound without his hamstring bothering him. The reliever is expected to begin the season on the disabled list and will likely hang back in extended spring training for a bit. Edward Mujica will be the Red Sox' primary closer while Uehara is on the shelf.
Mar 30 - 9:17 PM

Red Sox manager John Farrell said Monday that he doesn't expect Koji Uehara (hamstring) to be ready for Opening Day.

It's not a big surprise at this point. Uehara suffered a left hamstring strain about two weeks ago and is scheduled to throw a bullpen session Monday, but there's simply not enough time to get him ready for Opening Day. However, he should join Boston's bullpen relatively quickly if he can avoid setbacks. Edward Mujica will be the favorite for saves during his absence, but Farrell could also play the matchups.
Mar 30 - 4:04 PM

Red Sox manager John Farrell said that Koji Uehara is "not likely" to be ready for Opening Day after feeling more discomfort in his left hamstring during a bullpen session Saturday.

It's not clear at this point how long he might be sidelined, but the veteran reliever has dealt with the hamstring ailment for nearly two weeks now and doesn't seem to be getting much better. Edward Mujica will be the primary closer for the Red Sox until Uehara is ready, although Farrell wouldn't rule out using Junichi Tazawa, Tommy Layne and Alexi Ogando should the matchups present themselves.
