Hisashi Iwakuma turned in a dominant performance in earning a no-decision against the Twins on Sunday, allowing just three hits and one run over 8 2/3 innings before the Mariners picked up a 4-1 win in extra innings.
Iwakuma struck out eight and walked one in the spectacular performance, but he would not earn a victory. After Nelson Cruz homered in the top of the ninth to give the Mariners a 1-0 lead, Iwakuma would trot out to try for the complete game and subsequently allow a solo home run to Brian Dozier. The Mariners would eventually win 4-1 in 11 innings. No-decision aside, it was a great start. He's been inconsistent since returning from injury in early July, but outings like this are a reminder that expectations should be initially tempered when a player returns from a long stint on the disabled list. For the season, Iwakuma holds a 4.31 ERA and 1.12 WHIP. There's still room for improvement on that ERA mark. He'll try to build off Sunday's strong start when he faces the Rangers in Seattle next time he toes the rubber. Aug 2 - 6:27 PM

According to Jeff Passan of Yahoo Sports, the Mariners are telling teams that they plan to keep Hisashi Iwakuma.

Seattle is well under .500 and Iwakuma is due to become a free agent this offseason, so it's an odd stance for the M's to take. The 34-year-old right-hander has posted a rough-looking 5.10 ERA in 47 2/3 innings this summer, but his peripherals are much better and he'd surely fetch some prospects in this market.

Hisashi Iwakuma served up six runs to the Diamondbacks in 5 2/3 innings, leaving with a loss on Tuesday.

Iwakuma was on a roll entering Tuesday's outing, with three quality outings in a row. But the D'Backs weren't impressed, pounding out 10 hits against the right-hander. He also walked one and struck out five as he watched his ERA balloon to 5.10. Iwakuma will try to right his ship when he takes the mound against the Twins in Minnesota.
Jul 29 - 1:13 AM

FOX Sports' Jon Morosi reports that the Mariners have heard from "several teams" interested in Hisashi Iwakuma.

However, Morosi adds that Seattle "still hasn't committed firmly to trading him." The Mariners are, at best, on the fringe of the Wild Card race and Iwakuma is a free agent after this season, but it doesn't appear they're ready to give up yet. Iwakuma has been limited to just seven starts this season due to injury but has been really good the last three times out, allowing a total of just four runs.

Hisashi Iwakuma earned a strong no-decision in Thursday afternoon's contest with the Tigers, allowing two runs on six hits over seven innings.

Iwakuma and David Price were locked in a fun little pitcher's duel on Thursday. For most of the game, Price held a 2-1 advantage, but the M's managed to tie things up with a Mark Trumbo single in the seventh. They would go on to win in 12 innings, though Iwakuma was long gone by that point. For his part, the pitcher allowed a two-run double to Victor Martinez in the first inning before settling down to shutout the Tigers over the next six innings. He struck out seven and walked two on the day. After missing over two months with a strained lat muscle, the Japanese import finally appears to be rounding into form and should be seriously considered for deeper mixed-league formats. Overall, he's the owner of a 4.50 ERA, 1.17 WHIP and 32/7 K/BB ratio over 42 innings. He's never posted an ERA higher than 3.52 in his career. He'll try to keep his good roll going in a home start against the Diamondbacks next time he toes the rubber.
Jul 23 - 5:43 PM

Hisashi Iwakuma racked up five strikeouts over 5 2/3 innings as he defeated the Yankees in New York on Saturday.

The right-hander allowed just two runs on five hits in the contest. All of the damage against him came on a two-run homer off the bat of Brian McCann in the fourth inning. After delivering a clunker in his return from the disabled list, Iwakuma has now won two consecutive starts and looks to be getting stronger as he goes. He'll take on the Tigers in Detroit his next time out on Thursday.
Jul 18 - 4:22 PM

Hisashi Iwakuma was much, much better in his second start back from the DL, shutting out the Angels for eight innings in a win Saturday.

Iwakuma allowed just three hits in the gem. He walked two and struck out six. It's the first time in five outings this year that he's turned in a quality start and also the first time the Mariners have prevailed in one of his starts. We wouldn't necessarily expect a bunch more outings like this, but he should have some mixed-league value the rest of the way.
Jul 12 - 2:01 AM

Hisashi Iwakuma, making his first start since April 20, yielded five runs in five innings in Monday's 12-5 loss to the Tigers.

The first four runs each came as a result of a solo home run, hit by Nick Castellanos, Victor Martinez, J.D. Martinez, and Yoenis Cespedes. Iwakuma allowed a single after the Cespedes home run in the sixth inning before departing. All told, he gave up eight hits, walked none, and struck out three. He now has a 7.17 ERA, 1.45 WHIP, and a 14/3 K/BB ratio in 21 1/3 innings across four starts. Iwakuma will try to stabilize in his final start before the All-Star break, at home against the Angels.
Jul 7 - 1:42 AM

Mariners activated RHP Hisashi Iwakuma from the 15-day disabled list.

The right-hander has been sidelined since late April due to a strained lat muscle. He also had a blister issue in his last rehab start, but manager Lloyd McClendon said that Iwakuma will not be under a strict pitch count Monday when he takes on the Tigers. Fantasy owners can probably feel free to go ahead and ride with him.
Jul 6 - 4:54 PM

According to Mariners manager Lloyd McClendon, there will be "no restrictions" on Hisashi Iwakuma (lat) when he returns to start against the Tigers on Monday.

Iwakuma last started on April 20. While McClendon and the team are not placing any restrictions on Iwakuma, it's reasonable to assume that he'll be at least be relatively limited in the number of pitches he throws in his first few starts back. He sported a 6.61 ERA, 1.41 WHIP and 11/3 K/BB ratio over 16 1/3 innings and three starts prior to the DL stint.
Jul 6 - 11:04 AM

Hisashi Iwakuma (lat) will rejoin the Mariners rotation on Monday against the Tigers.

The right-hander has been sidelined since April 21 due to a strained lat muscle. In three starts with the M's before hitting the disabled list, he registered a 6.61 ERA, 1.41 WHIP and 11/3 K/BB ratio across 16 1/3 innings.
Jul 4 - 9:23 AM

The Mariners will not activate Hisashi Iwakuma (lat) from the disabled list to start on Sunday.

Mike Montgomery will stay on turn and take the ball Sunday. The Mariners have not made a decision on the next step for Iwakuma, but it's possible he'll make another rehab start. He could also rejoin Seattle's rotation early next week.
Jul 3 - 5:53 PM

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

It's unclear if he's going to need one final minor league rehab start, or be cleared to rejoin the Mariners rotation immediately. M's manager Lloyd McClendon said he'll elaborate on the team's rotation plan on Friday.
Jul 2 - 7:05 PM

Hisashi Iwakuma (lat) doesn't think the blister that forced him from his rehab start Tuesday will be an issue.

Iwakuma noted that he's had numerous blister problems over the years and that the Mariners' training staff knows how to treat them. It remains to be seen whether the M's share his opinion, but either way this isn't a big setbacks. Iwakuma could rejoin Seattle's rotation as soon as Sunday.
Jun 30 - 11:24 PM

Hisashi Iwakuma (lat) had to leave Tuesday's rehab start with Triple-A Tacoma due to a blister on his pitching hand.

He pitched well before exiting, allowing just one run on five hits and one walk while striking out six. Iwakuma's splitter has often given him blister issues, but it's unclear at this point if this is a notable setback. Tuesday's rehab start likely was going to be his last, although the Mariners hadn't confirmed as much. More should be known about Iwakuma on Wednesday.
