Date:

Hisashi Iwakuma (shoulder) has resumed playing catch.

It's just flat-ground tossing from 70 feet for now, but it's progress after Iwakuma was shut down for a couple weeks following renewed right shoulder soreness. A potential return date remains very much up in the air.
Jul 16 - 12:39 PM

Hisashi Iwakuma (shoulder) has been shut down after feeling discomfort during his most recent bullpen session.

Iwakuma received a cortisone shot in his shoulder in hopes of getting him over the hump. The veteran right-hander has already been sidelined since early May and now his absence appears likely to stretch well into the second half.
Jul 4 - 3:37 PM

There remains no timetable for Hisashi Iwakuma's (shoulder).

Iwakuma was re-evaluated late last week after feeling renewed soreness in his right shoulder, and he's still limited to receiving treatment for now. "I know he's still getting treatment and working his tail off, but I haven't heard anything different there," Mariners manager Scott Servais said. Iwakuma has been out since early May.
Jun 27 - 10:08 PM

Hisashi Iwakuma will be re-evaluated due to continued soreness in his right shoulder.

Iwakuma had been slated to return this weekend before the Mariners said earlier this week that he'd make at least one more rehab start. Now he's been pulled off his rehab assignment in order to be re-examined. Obviously, a potential timetable is totally up in the air for Iwakuma.
Jun 23 - 10:42 AM

Hisashi Iwakuma (shoulder) is slated to make one more rehab start.

Iwakuma was on track to return this weekend against the Astros, but the Mariners have decided against that move after the 36-year-old right-hander made it just two innings Monday with Triple-A Tacoma. He has been on the disabled list since early May with right shoulder inflammation.
Jun 20 - 6:44 PM

Hisashi Iwakuma (shoulder) allowed four runs, four hits and two walks with three strikeouts over two innings in a rehab start with Triple-A Tacoma on Monday.

Iwakuma had a 32-pitch inning in the second, totaling 49 pitches overall. He was cleared for 70 pitches by the training staff. It's not a terribly encouraging outing for what was expected to be his final minor-league rehab start before returning to the big club this weekend.
Jun 20 - 12:15 AM

Hisashi Iwakuma (shoulder) will rejoin the Mariners' rotation next Saturday or Sunday against the Astros.

The M's will also be getting Felix Hernandez (shoulder) back next weekend. They have not announced who Iwakuma and Hernandez will be replacing in the rotation.
Jun 18 - 1:31 PM

Hisashi Iwakuma (shoulder) will make another rehab start early next week at Triple-A Tacoma.

Iwakuma allowed just one hit over four scoreless innings Wednesday with High-A Modesto, but the Mariners want to get him properly stretched out before they bring him back. He'll try to go six-plus innings in his next rehab outing. The veteran right-hander has been on the disabled list since early May due to shoulder inflammation.
Jun 15 - 11:46 AM

Hisashi Iwakuma (shoulder) allowed one hit while striking out four over four scoreless innings in his minor-league rehab start wigh High-A Modesto on Wednesday.

Iwakuma was on point in this rehab outing, throwing 43 pitches (33 for strikes). Earlier this week, general manager Jerry Dipoto said that the veteran right-hander might need just the one rehab start before he is ready to rejoin the Mariners. A bout of right shoulder inflammation has sidelined him since early May.
Jun 14 - 11:10 PM

Hisashi Iwakuma (shoulder) is scheduled to make a minor-league rehab start for Class A Modesto (Calif.) on Wednesday.

General manager Jerry Dipoto said in a radio interview that the plan was just for one rehab start and then a return to the big club, so Iwakuma could be back as soon as early next week. Fantasy owners will want to play it safe and allow him one or two starts with the big club to knock off the rust before trusting him again.
Jun 11 - 11:44 PM

Hisashi Iwakuma (shoulder) completed a 50-pitch bullpen session on Thursday.

Next will be a two-inning simulated game on Sunday. It took a bit longer than expected, but it appears Iwakuma has finally turned the corner in his recovery. He's been out with shoulder inflammation since early May.
Jun 8 - 7:39 PM

Hisashi Iwakuma (shoulder) played catch Wednesday without issue.

And if his simulated game on Thursday goes smoothly, the veteran right-hander should be cleared to begin a minor league rehab assignment next week. Iwakuma has been on the disabled list since May 7 because of right shoulder inflammation. He's on track to return to the Mariners' rotation before the end of June.
Jun 8 - 11:15 AM

Hisashi Iwakuma (shoulder) threw two simulated innings Saturday as he continues to recover from a sore shoulder.

Iwakuka called the outing a "step in the right direction," and said he feels like he is making progress while no longer feeling discomfort in his shoulder. Manager Scott Servais indicated Iwakuma is likely to need one more sim game before being green-lighted for a minor-league rehab assignment, likely requiring at least two starts. If that timetable holds up he might be able to return by late June.
Jun 3 - 9:32 PM

Hisashi Iwakuma (shoulder) threw a 25-pitch bullpen session on Tuesday afternoon.

Iwakuma will throw one more bullpen session before beginning to face live hitters. His rehab from an inflamed right shoulder is finally headed in a positive direction. The veteran starter has been on the disabled list since May 10, retroactive to May 7.
