Hisashi Iwakuma told the Japan Times that the Mariners have made him an offer to return.
Iwakuma became a free agent earlier this month after the Mariners declined his $10 million option for 2018. The veteran right-hander says that a return is "not a done deal," but "hopefully I will be able to make a positive announcement soon." Iwakuma, 36, was limited to just six starts this season due to shoulder issues and required an arthroscopic debridement in September. He's hoping to be ready around the start of next season.

Mariners declined RHP Hisashi Iwakuma's $10 million club option for 2018.

Iwakuma went down with a shoulder injury in early May and never returned to the field, eventually requiring an arthroscopic debridement in September. The veteran right-hander will turn 37 years old next April.
Nov 2 - 2:18 PM

Hisashi Iwakuma underwent an arthroscopic debridement on his ailing right shoulder.

He won't resume throwing for five months, which could put the start to his 2018 season in jeopardy. The 36-year-old hurler finished the injury-plagued 2017 season with a 4.35 ERA, 1.26 WHIP and 16/12 K/BB ratio in just 31 innings over his six starts.
Sep 29 - 7:21 PM

Hisashi Iwakuma admitted Tuesday that there is something structurally wrong with his right shoulder.

He's said to be considering all options, some of which are surgical procedures. Iwakuma hit the disabled list in early May with inflammation in his right shoulder and was never able to return to the Mariners' rotation, finishing the 2017 season with a 4.35 ERA in six starts. The 36-year-old is scheduled to become a free agent in November.
Sep 19 - 7:26 PM

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.
Sep 19 - 6:48 PM

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

While the Mariners haven't ruled him out, they haven't been counting on Iwakuma to return this season. He's been on the shelf since the beginning of May with what was called shoulder inflammation.
Sep 14 - 5:03 PM

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.
Sep 6 - 5:32 PM

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.
Aug 22 - 8:22 PM

Hisashi Iwakuma (shoulder) was scheduled to throw a bullpen session Monday.

Iwakuma is ready to test his shoulder again after he struggled with his mechanics during a simulated game earlier this month. He's already experienced multiple setbacks, so the Mariners can't count on him at this point. Iwakuma has been out since early May.
Aug 22 - 10:27 AM

Hisashi Iwakuma (shoulder) struggled with his mechanics during a simulated game on Friday.

The 25-pitch bullpen session did not go well by all accounts. Iwakuma had been ticketed for a potential simulated game early next week, which will now be pushed back. With all of the injuries facing the M's rotation, they may be forced to look outside the organization for additional help.
Aug 11 - 7:40 PM

Hisashi Iwakuma (shoulder) could throw a simulated game in the next week.

Iwakuma has made it through a couple of bullpen sessions without issue and is just about ready to take the next step in his rehabilitation from a right shoulder injury. The veteran starter has been on the disabled list since early May.
Aug 10 - 3:30 PM

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.
Jul 29 - 4:32 PM

Mariners transferred RHP Hisashi Iwakuma from the 10-day disabled list to the 60-day disabled list.

The move clears a spot on the 40-man roster for Danny Espinosa. Iwakuma has resumed a throwing program but there's no timetable for his return from shoulder issues.
