Mariners manager Scott Servais acknowledged Tuesday that Hisashi Iwakuma (shoulder) is likely done for the year.

Iwakuma landed on the disabled list at the beginning of May with right shoulder inflammation and he hasn't been able to get over the hump in his rehab. The 36-year-old is scheduled to become a free agent in November, having made just six total starts in 2017.

Hisashi Iwakuma is looking for additional opinions from doctors as he struggles to rehab his shoulder.

Hisashi Iwakuma (shoulder) played catch in the outfield on Wednesday.

Iwakuma has been stepping up his efforts of late, as he threw a bullpen session on Tuesday and is expected to throw a simulated game on Saturday. While he is making clear progress in his recovery from a right shoulder injury, it remains uncertain as to whether he will be able to return to action before the end of the season.

Hisashi Iwakuma (shoulder) will face live hitters in a simulated setting on Saturday.

Iwakuma made it through another bullpen session Tuesday without issue and is finally trending toward a return to the Mariners' active roster, though it's not a certainty he will actually make it back before the end of the regular season. "He's been out a long, long time," manager Scott Servais said Tuesday. "Unfortunately, his arm hasn't responded real consistently. I hope we can get him out there, but that would just be a bonus right now."
Sep 6 - 11:30 AM

Hisashi Iwakuma (shoulder) threw 40 pitches in a bullpen session on Saturday.

Iwakuma hasn't made enough progress for the Mariners to project him to return before the end of the year. Even if he's ready to pitch, the arm strength probably isn't there to allow him to get major league hitters out.
Sep 2 - 7:06 PM

Mariners manager Scott Servais said Hisashi Iwakuma (shoulder) looked only "OK" in his bullpen session Monday.

"He’ll probably throw another bullpen," Servais told reporters after the workout. "We’re running out of time. Guys have to be able to ramp it up pretty quickly to have any chance to make an impact for us down the stretch ... Last time, Kuma got to this point, then he got to the simulated game, we put a hitter in there, and it was like, `Whoa, this isn’t even close.’ It didn’t feel good." The veteran right-hander has been out since early May and there is no timetable for him to embark on a minor league rehab assignment. He might not make it back this year.

Hisashi Iwakuma (shoulder) still hasn't been cleared for mound work.

Iwakuma has been long tossing up to 150 feet before games but is still waiting for clearance to resume mound work. Hopefully he picks up here soon. "If everything went right, maybe he could possibly get back in the mix," said manager Scott Servais. "It's going to take some time to get him built up, but he has to be pain-free and get on the mound and go from there. I don't have a timetable for any of that." Lingering shoulder soreness has sidelined the right-hander since early May.
