Koji Uehara RP BOS 9 Hrs

Koji Uehara returned to action on Thursday April 17.

Koji Uehara RP BOS 13 Hrs

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 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.

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.

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.

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.

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.

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.

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.

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.
