Koji Uehara earned his 17th save of the season after pitching a scoreless ninth inning against the Blue Jays, finalizing Monday's 3-1 victory.

Uehara needed only 11 pitches, getting Jose Reyes to foul out, Josh Donaldson to fly out, and Jose Bautista to pop up. He's 17-for-19 in save chances to date with a 3.00 ERA and a 30/6 K/BB ratio in 27 innings.

Koji Uehara slammed the door on the Rays for his 16th save as the Red Sox won 5-3 on Sunday.

Uehara got two quick outs on a strikeout of Kevin Kiermaier and an Asdrubal Cabrera ground out. However, Grady Sizemore kept hope alive with a double, then advanced to third base on a wild pitch. Uehara bounced back to get Evan Longoria on a fly out to right field to end the game. Despite a few leaky outings in June, Uehara has been reliable this season, getting the save in 16 of 18 opportunities with a 3.12 ERA and a 30/6 K/BB ratio in 26 innings.

Koji Uehara pitched a perfect 10th inning Friday against the Rays for his 15th save of the season.

Uehara struck out two batters in the frame and needed just 10 pitches to lock down the victory. The 40-year-old has had some rough outings this month, which is why his ERA sits at an uncharacteristic 3.24 for the year, but he still has an excellent 29/6 K/BB ratio in 25 innings. It would be interesting to see what kind of market there is for him if the Red Sox decide to sell off pieces before July 31.

Koji Uehara tossed a scoreless ninth inning Friday against the Athletics for his 12th save of the season.

Asked to hold a two-run lead, Uehara gave up an infield single to Brett Lawrie and a double to Josh Phegley, so it wasn't without a little bit of drama. However, he managed to wiggle his way out of the jam to lock down the victory. Uehara is 12-for-14 in save chances this season to go along with a 2.50 ERA and 20/6 K/BB ratio over 18 innings.
Jun 5 - 10:16 PM

Koji Uehara kept the Twins off the board in the ninth inning, helping the Red Sox eke out a 1-0 win on Tuesday.

Uehara allowed a two-out walk to Trevor Plouffe, but was able to get Kurt Suzuki to fly out to end the game. The 40-year-old has been terrific for the Red Sox this year, going 11-for-13 in save opportunities with a 1.59 ERA and a 19/6 K/BB ratio in 17 innings.
Jun 2 - 9:41 PM

Koji Uehara could not hold onto a 3-2 ninth inning lead, blowing the save when he allowed a two-run double to Josh Hamilton.

The inning started out ominously enough, as Hanser Alberto reached base on an error by Pablo Sandoval. After recording the next two outs, Uehara intentionally walked Prince Fielder to bring the pinch-hitting Josh Hamilton to the plate. Hamilton's subsequent two-run double ended the game. With the blown save, Uehara fell to 10-for-12 in save opportunities. He holds a 1.69 ERA and 18/5 K/BB ratio over 16 innings and remains a reliable closer as long as he's healthy.
May 31 - 7:00 PM

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.
Apr 29 - 10:58 PM

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.
