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.
Apr 21 - 1:43 AM

Hisashi Iwakuma allowed four runs in five innings, taking a no-decision in Tuesday's loss to the Dodgers.

Iwakuma's mediocre start to the 2015 season continues, as he had given up five runs in six innings to the Angels previously. The right-hander yielded six hits and walked three while striking out five against the Dodgers. Andre Ethier and Alex Guerrero both homered off of him. Iwakuma will try to turn things around in his next start at home against the Astros.
Apr 15 - 2:01 AM

Hisashi Iwakuma allowed five runs (four earned) in six innings during Wednesday's loss to the Angels.

Given the way he started the game, it could have been much, much worse. Iwakuma's stuff lacked location and bite early on, leading to a barrage of first inning runs. Albert Pujols socked a two-run homer off Iwakuma in the first and two more runs would score on a fielding error by Robinson Cano. Following a Mike Trout sacrifice fly in the second, Iwakuma was down 5-0 and had already thrown over 50 pitches. He didn't allow another run, though, and finished his six innings having thrown a respectable 92 pitches. He struck out three and did not walk a batter. Iwakuma's dealing with a blister suffered in spring training. His postgame comments should clarify whether or not that was an issue early in this start.
Apr 9 - 1:16 AM

Hisashi Iwakuma didn't throw any splitters during a two-inning minor league appearance Thursday due to a blister he developed in a March 28 outing.

Iwakuma's splitter has often given him blister issues over the past few years. It's something he knows how to manage at this point and he thinks he'll be fine for his first regular season start. "It’s a good thing and a bad thing at the same time," he said. "When I get that blister, that means my finger had a good grip on the ball. So that’s a good thing. But at the same time, you have to prevent it from getting to be a problem. You just have to fight it because it is what it is. My finger should be ready by my next start."
Apr 3 - 10:25 AM

Hisashi Iwakuma gave up four runs in five innings as the Giants held on for a 9-8 victory over the Mariners on Saturday.

Iwakuma was making his first start in a week and a half, allowing his first runs of the spring in the process. Two of the five hits he allowed went for extra bases, and he walked two as well. The right-hander did strike out four. The outing isn't concerning at all, as Iwakuma should register above-average numbers during the regular season. He posted a 3.52 ERA with a 154/21 K/BB ratio in 179 innings last season.
Mar 28 - 7:42 PM

Hisashi Iwakuma will make his next scheduled start Thursday in a simulated game against minor leaguers.

Iwakuma was originally scheduled to start Thursday against the Athletics, but Mariners manager Lloyd McClendon wants to avoid having him face a team he'll see in the early part of the season. The 33-year-old owns a 3.07 ERA across his first three seasons in the majors and remains a very strong fantasy option.
Mar 10 - 11:44 AM

Hisashi Iwakuma tossed two perfect innings in Saturday's loss to the Diamondbacks in the Cactus League.

Iwakuma made quick work of his competition, throwing 16 strikes among 22 pitches. The start was his first of the spring. The 33-year-old went 15-9 with a 3.52 ERA in 28 starts last season, and he should have another strong season in 2015.
Mar 7 - 6:00 PM

Hisashi Iwakuma indicated Sunday that he's not interested in returning to Japan to pitch when his contract expires after the 2015 season.

"I would want to stay here and pitch", the 33-year-old said through his interpreter. He has been a tremendous addition to the Mariners rotation since coming stateside, registering a 3.07 ERA, 1.09 WHIP and 440/106 K/BB ratio over 524 innings in his three seasons.
Feb 22 - 4:35 PM

Mariners general manager Jack Zduriencik said trading Hisashi Iwakuma "wouldn't make any sense."

"We're not trading Iwakuma," Zduriencik told Larry Stone of the Seattle Times. "Honestly, I have no idea where that came from. It wouldn't make any sense." A few weeks back it was reported the M's were fielding inquiries on Iwakuma, but he's very good and will be very inexpensive in 2015. While you can never say never -- the A's shot down Josh Donaldson trade rumors before eventually dealing him last week -- the Mariners would need to be blown away to deal the 33-year-old.
