Hisashi Iwakuma yielded one run over 5 2/3 innings against the Royals on Friday.
Iwakuma blanked the Royals until Paulo Orlando led off the fifth with a homer. He struck out four and walked none. His last two Cactus League outings were very shaky, so this should restore some confidence going into the season. Still, he’s not the fantasy option he once was. He turns 36 in April and his strikeout and walk percentages are headed in the wrong direction. Mar 24 - 7:00 PM

Hisashi Iwakuma allowed three runs on six hits over 3 2/3 innings in Saturday's Cactus League game against the Giants.

Iwakuma gave up RBI hits to Joe Panik and Jarrett Parker in the first inning. Parker would also burn him for a solo home run in the third. Outside of the run-scoring damage on his line, Iwakuma struck out five without walking a batter. Iwakuma will be part of the Opening Day rotation, but has struggled this spring, posting a 9.58 ERA in four starts. It should be noted that he surrendered seven runs in his prior outing, which is cause for some of the bloat on that earned run mark.
Mar 18 - 7:09 PM

Hisashi Iwakuma was tagged for seven runs over 2 2/3 innings in Monday’s loss to the Brewers in Cactus League action.

It was a rough one. Iwakuma allowed six hits, including back-to-back home runs to Keon Broxton and Travis Shaw in the second inning. He also walked a pair. Iwakuma was one of three Mariners’ pitchers to allow at least seven runs, so it was that sort of afternoon. The veteran right-hander will look to improve next time out.
Mar 13 - 8:59 PM

Hisashi Iwakuma hurled two innings of scoreless ball in Wednesday's Cactus League loss to the Indians.

Iwakuma walked one and struck out two while allowing one hit over his two innings of work. This past season, the veteran right-hander posted a 4.12 ERA over 33 innings. He had put up earned run marks below 3.55 in each of his first four major league seasons before taking a bit of a slide in 2016. He holds borderline mixed-league intrigue, nothing more.
Mar 9 - 12:32 AM

Making his spring debut, Hisashi Iwakuma yielded one run over two innings of work Friday against the Rangers.

It was far from a clean outing, as he gave up four hits and walked one, but he avoided further damage in the second inning after Ryan Rua tried to stretch a double into a triple. After a deal with the Dodgers fell through due to medical concerns, Iwakuma dropped off to a 4.12 ERA (98 ERA+) over 33 starts last season. He’s a fringe option in mixed leagues at this point.
Mar 3 - 6:06 PM

Hisashi Iwakuma is scheduled to throw a side session on Tuesday.

The Mariners have Iwakuma on what is termed a "go slower" plan this spring, easing the veteran right-hander into action. He isn't expected to make his Cactus League debut until March 3 at the earliest.
Feb 25 - 10:29 AM

Hisashi Iwakuma was charged with five runs in just 3 2/3 innings but escaped with a no-decision in Saturday's crushing loss to the Athletics.

The A's strung together several hits in the third inning to plate four runs and added another tally in the fourth frame. All told, Iwakuma gave up nine hits and a walk while striking out five in the abbreviated outing. His record holds at 16-12 but his ERA climbs over four to 4.12 after 33 starts. He falls just shy of the 200 inning mark, finishing with 147 strikeouts and 46 walks in 199 frames at the age of 35.

Hisashi Iwakuma pitched six innings of one-run ball Monday against the Astros.

Iwakuma was in line for the victory when he left, but Edwin Diaz blew the save, leaving Iwakuma with a no-decision for the first time in 24 starts since May 14. Jake Odorizzi has had like 36 no-decisions since then.

Hisashi Iwakuma was demolished in Tuesday's loss to the Blue Jays, yielding six runs (five earned) on eight hits over 3 1/3 innings.

Iwakuma kept the Blue Jays off the scoreboard altogether through the first three innings. Then, the fourth inning happened. The frame opened innocently enough with a strikeout of Edwin Encarnacion. That was followed by a Jose Bautista single, a two-run homer off the bat of Russell Martin, a Troy Tulowitzki single, a two-run home run by Michael Saunders, a Kevin Pillar double and an RBI single by Ezequiel Carrera to cap it all off before Iwakuma was mercifully relieved of duty. Yikes. The veteran right-hander saw his ERA jump from 3.87 to 4.04 by the time the dust had settled. He will try for a more favorable result in a road start against the Astros next time he toes the rubber.

Hisashi Iwakuma picked up his 16th win after allowing one run in 6 1/3 innings Wednesday against the Angels.

The Mariners won 2-1 on the strength of Iwakuma's arm and solo homers from Kyle Seager and Nelson Cruz. Iwakuma's 16 wins are a career high. He's turned in three quality starts in three tries this month.

Hisashi Iwakuma won for the 15th time this season after allowing two runs in 6 2/3 innings.

That matches his career high for victories. Iwakuma hasn't enjoyed the same kind of success this year that he did when he first entered the league in 2012, but that was to be expected at age 35. He's been plenty solid in the middle of the Mariners rotation, and the Dodgers probably wish they had him right about now.

Hisashi Iwakuma logged a quality start in Sunday's loss to the Angels, allowing three runs on eight hits over seven frames.

The veteran right-hander walked one and punched out five on the afternoon. Most of the damage against him came in the first inning, where Albert Pujols and C.J. Cron belted back-to-back two-out homers. He'll look to improve upon a 4.01 ERA and 1.29 WHIP when he takes on the Athletics in Oakland on Friday.
Sun, Sep 4, 2016 07:14:00 PM

Hisashi Iwakuma was lit up for five runs over three innings in Monday's loss to the Rangers.

This game was essentially over after the third inning, as the Rangers plated one run in the first against Iwakuma and four more in the third. August concluded on a sour note for the right-hander, but it was a good month for him overall with a 3.28 ERA. He'll get the Angels for his first start of September.

According to MLB Trade Rumors, Hisashi Iwakuma's 2017 option has vested.

Iwakuma got there when he reached 162 innings for the year in a start against the Yankees last week. While the option is worth $14 million, his contract also stipulates that he must finish the season without suffering a specific injury. The 35-year-old has struggled a bit recently, but he has managed to remain healthy so far. But nothing is guaranteed yet. Iwakuma's contract also includes a club/vesting option for 2018.

Hisashi Iwakuma turned in a quality start in Wednesday's loss to the Yankees, surrendering three runs on six hits over six innings.

Iwakuma struck out three and walked two in the contest. Gary Sanchez burned him for a solo home run in the first inning (Gary Sanchez does that to people), while a Tyler Austin RBI single in the second and a Brett Gardner sacrifice fly in the fourth completed the scoring on his line. This is just what Iwakuma does. He has allowed more than three runs just twice in his last 10 starts. The veteran right-hander will carry a 3.81 ERA, 1.27 WHIP and 118/36 K/BB ratio (163 innings) into a road date with the Rangers next time he toes the rubber.
