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.

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.

Red Sox manager John Farrell said Saturday that Koji Uehara (hamstring) has not been ruled out for Opening Day.

"He's a one-inning reliever, a veteran guy", Farrell said Saturday, indicating that he doesn't need much in-game preparation to get ready for the regular season. In the event that Uehara is unable to go, Edward Mujica is the favorite to see early save chances for the Red Sox.

Koji Uehara (hamstring) made 60 throws off flat ground Thursday.

Uehara strained his left hamstring early last week while doing some conditioning work, but Red Sox manager John Farrell called Thursday a "sizable step" for him. The next step calls for him to throw a bullpen session on Saturday. He remains a question mark for the start of the season. Edward Mujica would fill in at closer if he needs to miss some time.
Mar 26 - 4:14 PM

Koji Uehara (hamstring) will throw on flat ground Thursday and is lined up for a bullpen session this weekend.

The workouts should give the Red Sox a better idea about his status for the opening of the regular season. Uehara strained his left hamstring early last week while doing some conditioning work. If he's not ready come April 6, Edward Mujica would presumably fill in at closer for Boston.
Mar 26 - 10:14 AM

Ian Browne of writes that Red Sox manager John Farrell "seems less sold" on Koji Uehara (hamstring) than he did a week ago.

Uehara strained his left hamstring a week ago and has resumed throwing and agility drills in recent days, but it's unclear when he'll be ready to return to game action. Be sure to follow this situation closely in the coming days. Edward Mujica would likely fill in at closer if Uehara needs extra time to get ready.

Koji Uehara (hamstring) could long-toss on Friday.

Uehara strained his left hamstring on Tuesday. While it's good that he might be able to long-toss on Friday, the Red Sox won't let him throw from a mound again until he doesn't feel anything in his hamstring. Uehara is hopefuly of being ready for Opening Day.
Mar 19 - 6:35 PM

Koji Uehara (hamstring) expects to be ready for Opening Day, but conceded Wednesday that it could be a "close call."

Mar 18 - 11:45 AM

Red Sox manager John Farrell said that Koji Uehara will play catch, but won't get back on the mound until "he can tolerate the stress" in his strained left hamstring.

Mar 18 - 10:29 AM

Koji Uehara suffered a strained left hamstring on Tuesday morning in Red Sox camp.

It's going to cost him some Grapefruit League appearances, but the veteran closer should be fine by Boston's regular-season opener. Uehara has allowed seven hits and two earned runs in three innings this spring. He strained his hammy while running.
Mar 17 - 4:31 PM

Koji Uehara allowed a run and three hits in his inning of work against the Pirates on Saturday.

They weren't bloops today; Uehara gave up two well-hit doubles in the frame. He still has a few weeks left to find his best splitter, but he hasn't looked particularly strong this spring.
