Mariners manager Lloyd McClendon said Sunday that Hisashi Iwakuma (lat) will make at least three rehab starts.

Iwakuma allowed one run over 3 2/3 innings in his first rehab start with Low-A Everett on Saturday. The M's want him to get his pitch count up to 100 before he's activated and McClendon also said he'd like to see a little more velocity. Iwakuma has been on the shelf since April 21 with the strained lat.
Jun 21 - 2:32 PM

Hisashi Iwakuma (lat) will begin a rehab assignment with Low-A Everett on Saturday.

He was cleared for game action after getting through a simulated game on Monday with no issues. It's not clear how many rehab starts Iwakuma will require, but he's missed nearly two months so it should be a few. Stash him away in fantasy leagues if he had been dropped.
Jun 15 - 6:45 PM

Hisashi Iwakuma (lat) will throw a 45-pitch simulated game on Monday.

Iwakuma's very, very close to earning a rehab assignment. He threw a successful bullpen session on Thursday and should all go well on Monday, he could be pitching for Triple-A Tacoma next weekend, soon to return to the majors after that.
Jun 12 - 5:04 PM

Hisashi Iwakuma (lat) threw a successful bullpen session on Thursday and could soon be cleared for a minor league rehab assignment.

He continues to progress in his recovery from a lat strain, though he will still need a handful of minor league rehab starts before he's ready to rejoin the Mariners rotation. Barring any setbacks, he could return before the end of June.
Jun 11 - 7:35 PM

Hisashi Iwakuma (lat) threw a successful bullpen session on Thursday without any issues.

Iwakuma threw 27 pitches during the session, all fastballs, and said he felt good afterwards. He's still a few weeks away from a potential return to the Mariners.
Jun 4 - 8:30 PM

Hisashi Iwakuma (lat) is on track to begin a rehab assignment in about two weeks.

It's very tentative, as Iwakuma won't resume throwing off a mound until Thursday. Mariners manager Lloyd McClendon said he'd like for Iwakuma to make 2-3 rehab starts before returning, so he's looking at a late-June return even in a best-case scenario.
Jun 1 - 6:42 PM

Hisashi Iwakuma (lat) played catch again on Thursday.

Iwakuma was shut down for a while after having a setback with his strained right lat, but Mariners manager Lloyd McClendon said Thursday that "the discomfort and inflammation has dissipated to the point where he can get out and continue his rehab." The skipper added that he’d be "surprised" if Iwakuma were able to throw a bullpen session in the next 7-8 days, but it does appear progress is being made. "He feels real good," McClendon said. "And we’ll continue to progress with his rehab and see how that goes."
May 29 - 10:28 AM

Hisashi Iwakuma (lat) will be shut down from throwing for the next 10-14 days.

Iwakuma had been throwing on flat ground for the last week but has felt some stiffness in his strained right lat. It had already been looking like he wouldn't return before the end of May and now that's a certainty. Bob Dutton of the Tacoma New Tribune speculates that Iwakuma likely won't return for at least another six weeks.
May 12 - 6:28 PM

Mariners manager Lloyd McClendon said Hisashi Iwakuma (lat) has progressed to playing catch from 75 feet.

Despite the progress, McClendon said the right-hander is "a ways away." Iwakuma will almost certainly need a rehab start or two to get back up to speed once he's ready. The 34-year-old has been out since April 21 with the strained lat, and he likely won't be back before late May or early June as it stands now.
May 6 - 7:20 PM

Mariners manager Lloyd McClendon said Friday that Hisashi Iwakuma (lat) is still 3-4 weeks away from a return.

The M's had said when he went down a week ago that Iwakuma would be out 2-4 weeks. He hasn't had a setback, but rather it appears the club will make sure to proceed cautiously with the right-hander. Iwakuma did some long-tossing on Friday as he slowly ramps up his throwing program.
May 1 - 5:20 PM

Hisashi Iwakuma (lat) has done some very light throwing as well as strengthening exercises.

Iwakuma is nursing a Grade 1 right lat strain. The right-hander is expected to be on the shelf for 2-4 weeks, but the fact that he's already doing some throwing again is a good sign.
Apr 27 - 6:10 PM

Hisashi Iwakuma's MRI revealed a Grade 1 lat strain and he will miss 2-to-4 weeks.

Iwakuma didn't look right Tuesday against the Astros and was placed on the DL three days later. Now we know why his early season performance hasn't been up to snuff. Roenis Elias will be called up to take Iwakuma's place in the starting rotation.
Apr 25 - 8:35 PM

Mariners placed RHP Hisashi Iwakuma on the 15-day disabled list, retroactive to April 21, with a strained lat muscle.

Iwakuma was scheduled to start on Sunday, though it's unclear at the moment who will fill in for him. He posted a troublesome 6.61 ERA and 1.40 WHIP awhile allowing five home runs over 16 1/3 innings in his first three starts. The M's hope to have him back in the rotation in late-May.
Apr 24 - 9:10 PM

Hisashi Iwakuma turned in his third consecutive mediocre start, giving up four runs in 5 1/3 innings in Monday's loss to the Astros.

Iwakuma has been rather home run prone to start the year. He allowed two more on Monday night, giving him five in 16 1/3 innings to start the season. Overall, he gave up five hits, walked none, and struck out three. Iwakuma owns a 6.61 ERA and he has a good shot at lowering it as his next start comes against the Twins at home over the weekend.
