Hisashi Iwakuma improved to 2-4 after giving up three runs over six innings Friday versus the Reds.

The Mariners were down 3-0 before they rallied against the beleaguered Reds’ bullpen. This made a winner out of Iwakuma, who gave up six hits (including a solo homer by Zack Cozart) and three walks while striking out six batters. His line could have looked worse, but he managed to wiggle out of a couple of rallies. Iwakuma owns a 4.39 ERA and 1.41 WHIP through his first nine starts this season and is difficult to trust in mixed fantasy leagues at the moment. He’ll get the A’s next at home.
May 21 - 12:17 AM

Hisashi Iwakuma surrendered four runs on nine hits over 6 1/3 innings in earning a no-decision against the Angels on Saturday.

Iwakuma struck out two and walked one on the evening. He held the Angels off the scoreboard until the sixth inning. They would score one in that frame, then drive him from the game in what would ultimately turn into a five-run seventh. Through his first eight starts covering 49 1/3 innings, Iwakuma holds a middling 4.38 ERA, 1.40 WHIP and 38/14 K/BB ratio. He will take to the road for an interleague showdown with the Reds next time out.
May 15 - 12:48 AM

Hisashi Iwakuma was fantastic in Tuesday's 8-2 win over the A's, firing seven innings of four-hit, one-run ball.

Lovely work by Iwakuma, who struck out three and walked two. The strikeout total is modest enough, but the A's simply couldn't square the veteran right-hander up at any point. He did not allow an extra-base hit on the evening. The only run to score against him came in the sixth, when Jed Lowrie burned him for an RBI single. Otherwise, Iwakuma cruised. Through six starts (38 innings), he holds a 4.03 ERA, 1.32 WHIP and 28/11 K/BB ratio. In his four major league seasons prior to 2016, Iwakuma never finished with an ERA higher than 3.54 (2015). He will hit the dusty trail for a road outing against the Astros next time out.
May 4 - 12:51 AM

Hisashi Iwakuma fell to 0-3 after giving up five runs in five innings Wednesday against the Astros.

Iwakuma struck out seven, but he couldn't contain Jose Altuve, who had a homer and two doubles off him. He did pretty well against everyone else. After five starts, Iwakuma has a 4.65 ERA, but his 25/9 K/BB ratio is solid. It's not time to give up on him in mixed leagues just yet.
Apr 28 - 3:07 AM

Moved up to pitch in Felix Hernandez's slot, Hisashi Iwakuma held the Angels to two runs in eight innings on Friday.

The runs came on solo homers from Kole Calhoun and C.J. Cron. The Angels couldn't get anything else going, even though Iwakuma struck out just three on the night. Unfortunately, the performance still wasn't good enough to get Iwakuma his first win, though the Mariners did prevail in extra innings. Iwakuma is 0-2 with a 3.81 ERA and an 18/7 K/BB ratio after four starts.
Apr 23 - 1:43 AM

Hisashi Iwakuma put forth an uninspiring start in Sunday's loss to the Yankees, yielding four runs on eight hits over seven innings.

While Iwakuma did provide the Mariners nice length with his seven innings on the mound, this wasn't a particularly pretty start. He struck out just three and walked two while surrendering runs in the second, third and fifth innings. Over 18 innings (three starts), the veteran right-hander holds a 4.50 ERA, 1.56 WHIP and 15/6 K/BB ratio. Now 0-2 on the young season, Iwakuma will look to pick up victory No. 1 when he dances with the Angels in a road start next time out.
Apr 17 - 3:47 PM

Hisashi Iwakuma pitched six innings of three-run ball and struck out seven on Monday.

Iwakuma is winless despite back-to-back solid outings to begin the year. He has a 4.05 ERA with a 12/4 K/BB ratio and no homers allowed in 11 innings.
Apr 12 - 1:22 AM

Hisashi Iwakuma was touched up for three runs on eight hits and a walk across 4 1/3 frames on Monday against the Dodgers.

Justin Turner took Iwakuma deep in the outing. After firing five scoreless frames to kick off his Cactus League performance, the veteran right-hander has now allowed eight runs and 15 hits over his last seven innings. He'll try to right the ship this weekend.
Mar 21 - 6:39 PM

Hisashi Iwakuma was roughed up by the Giants on Wednesday, allowing five runs on seven hits over 2 2/3 innings.

Iwakuma walked two without striking out a batter. Most impressively (or perhaps terrifyingly), he wasn't even the worst pitcher in this Cactus League showdown. That honor would go to Jeff Samardzija, who allowed seven runs. Iwakuma, 34, holds a career ERA of 3.17 and offers a high-potential arm for all standard fantasy leagues.
Mar 16 - 7:34 PM

Hisashi Iwakuma fired three scoreless innings against the Giants on Friday.

Iwakuma limited the Giants to just one hit while walking one and striking out four. He has begun his spring with five scoreless innings. The veteran right-hander appears to be a bit of a injury risk after the Dodgers backed away from him over the winter due to a concern raised in a pre-signing physical, but there’s still plenty of upside if he’s healthy. While he owns a mediocre 3.53 ERA over the past two seasons, his 1.06 WHIP is 11th lowest (min. 300 IP) in that timespan.
Mar 11 - 5:42 PM

Hisashi Iwakuma tossed two scoreless innings Sunday in the Mariners' Cactus League win over Texas.

Iwakuma delivered two perfect frames in what was his spring debut, inducing four groundouts and one flyout while throwing 17 of his 23 pitches for strikes. Seattle re-signed the 34-year-old right-hander to a one-year, $12 million contract back in mid-December and will hope that he can maintain good health throughout 2016. He was limited to 129 2/3 innings in 2015. The new deal also includes vesting options for 2017 and 2018.
Mar 6 - 6:42 PM

CBS Sports' Jon Heyman reports that Hisashi Iwakuma is guaranteed $12 million in his new contract with the Mariners.

He gets a $1 million signing bonus and a $10 million salary in 2016, with a $1 million buyout on club options for 2017 and 2018. The $14 million 2017 option will vest if Iwakuma pitches 162 innings in 2016 and the $15 million 2018 option will vest if he reaches 162 innings in 2017 or a combined 324 frames from 2016-17. He can also earn an addition $2.5 million in incentives. All told, the deal could be worth a total of $47.5 million, which is $2.5 million more than he was going to be guaranteed from the Dodgers before failing a physical. Obviously there are health concerns with Iwakuma, but the Mariners got pretty lucky here with him falling back into their laps.

Mariners re-signed RHP Hisashi Iwakuma to a one-year contract with vesting options for 2017 and 2018.

It's a stunning turn of events for Iwakuma, who agreed to terms on a three-year, $45 million contract with the Dodgers nearly two weeks ago, only to have it fall apart due to an apparent issue with his physical. FOX Sports' Ken Rosenthal says the veteran righty can earn close to $45 million from Seattle if both options vest. The Mariners suddenly have plenty of rotation depth now, as Iwakuma's return likely pushes Nate Karns to the bullpen or Triple-A.

Hisashi Iwakuma is still negotiating with the Dodgers, per Mark Saxon of ESPN Los Angeles.

His reported three-year, $45 million pact was pulled off the table after a failed pre-signing physical, but Iwakuma is clearly still interested in heading to Los Angeles and the Dodgers apparently still want him at will surely be a lower rate. The 34-year-old right-hander struggled with a lat strain during the early part of the 2015 season, but he finished the year in good in health, having registered a 3.54 ERA across 20 starts.
