Hisashi Iwakuma earned his sixth victory of the season on Friday, giving up four runs on nine hits over seven frames against the Red Sox.

Iwakuma walked one and struck out four on the evening. His club provided him with plenty of early runs in this one and all he needed to do was cruise along and throw strikes. David Ortiz tagged him for a two-run homer in the fourth inning and the Red Sox scratched out another pair in the seventh against him. He'll carry a 4.18 ERA and 1.26 WHIP into Wednesday's start against the Tigers in Detroit.

Hisashi Iwakuma yielded three runs -- all coming on solo homers -- in seven innings in a win over the Rangers on Friday.

There have been eight occasions this season in which a pitcher has given up three homers and won. Iwakuma is responsible for two of those; he allowed three homers and four runs over seven innings against the Padres on May 31. In all, Iwakuma has allowed 13 homers in 83 2/3 innings, which puts him at the highest rate of his career. He still has some mixed league value, but not as much as he used to.
Jun 11 - 1:44 AM

Hisashi Iwakuma took a loss Sunday despite allowing just one earned run over seven innings against the Rangers.

Texas scored all three of its runs in the bottom of the fifth inning -- a messy frame all around for the visiting M's. Luis Sardinas and Stefen Romero committed errors within a few plays of each other, and they both led to runs for the home team. Iwakuma yielded just four official hits and one walk while striking out seven. He'll hope for better support next time out in a rematch with the Rangers.
Jun 5 - 5:44 PM

Hisashi Iwakuma survived three home runs to earn a win as the Mariners smashed the Padres 16-4 on Tuesday afternoon.

Iwakuma pitched seven innings and allowed only five hits, but three of those sailed over the fences at Safeco Field in Seattle. He gave up four runs on the strength of five strikeouts without walking anyone. His teammates pounded Padres pitching for 16 runs before Iwakuma gave up his first run in the sixth inning. The win evens Iwakuma’s record at 4-4 as his 4.41 ERA edges up. The aging hurler makes for a good matchup play moving forward.
May 31 - 8:59 PM

Hisashi Iwakuma surrendered three runs over seven innings Wednesday versus the A's.

Iwakuma beat the A's for the second time this month to run his record to 3-4 with a 4.33 ERA. He has an even tastier matchup with a start against the Padres due up next.
May 26 - 1:29 AM

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.
