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.

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.

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) played catch with good intensity Monday morning in Red Sox camp.

And he went through a range of agility drills on Sunday without issue. Uehara should be cleared to resume pitching in Grapefruit League games by the end of this week and he is expected to be fully recovered from his mid-March hamstring strain by Opening Day.

Koji Uehara (hamstring) went through some agility testing Sunday.

Uehara also threw long toss in the session. The reliever appeared to be fine, Boston Globe beat writer Pete Abraham said. Uehara should be back on the mound in a few days and likely won't be a question for Opening Day.

Koji Uehara (hamstring) played long toss on Friday without any difficulty.

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."

Uehara strained his left hamstring Tuesday and Red Sox manager John Farrell said Wednesday morning that he won't get back on the mound until "he can tolerate the stress" with his hamstring. He likely won't need many games to be ready for the season, but the situation is worth watching.
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.

Uehara suffered the injury Tuesday morning and the Red Sox aren't going to take any chances with him. He's not in jeopardy for missing the start of the season at this time, but he can't afford any setbacks.
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.
Mar 14 - 4:52 PM

Koji Uehara allowed one run and three hits in his inning Friday against the Marlins in his spring debut.

The Red Sox failed to land a shutdown eighth-inning guy this winter, keeping all of their eggs in Uehara's basket. He was so great prior to last August that it'd be crazy to write him off. Still, it'd be nice if Boston had a better backup plan.
Mar 6 - 4:40 PM

Koji Uehara acknowledged in Red Sox camp Monday that his arm bothered him at the end of the 2014 season.

Uehara surrendered 10 earned runs over his final nine appearances last year. "It was more physical," the right-hander told reporters in Florida. "I didn't talk about it at that time, but I think I'm over it." Boston felt comfortable enough to re-sign Uehara to a two-year, $18 million free agent contract in late October and the 39-year-old will open the 2015 campaign as the club's closer.
Feb 16 - 2:27 PM

Red Sox re-signed RHP Koji Uehara to a two-year, $18 million contract.

The Red Sox weren't expected to make Uehara a one-year, $15.3 million qualifying offer, but they didn't want him to hit the open market either. It's a fair compromise under the circumstances. Uehara faded down the stretch this season, but still ended up with 26 saves to go along with a 2.52 ERA and 80/8 K/BB ratio over 64 1/3 innings. He'll turn 40 next April and will enter the season as the Red Sox' closer.

Nick Cafardo of the Boston Globe reports that there "have been preliminary talks" between the Red Sox and Koji Uehara, but "the sides aren’t close to a deal."

The Red Sox would like to keep Uehara as their closer but are not expected to extend a qualifying offer of $15.3 million. Cafardo notes that a one-year deal that might include an option "would be preferable." Uehara lost his closer gig after struggling down the stretch but was terrific overall, posting a 2.52 ERA, 0.92 WHIP and 80/8 K/BB ratio over 64 1/3 innings.
