Iwakuma was roughed up for five runs on nine hits and one walk in 3.2 innings Saturday in a loss to the A's. He struck out five.

EDGE Analysis

It was third time in seven starts that Iwakuma failed to go four innings. Iwakuma was Seattle's most effective starter this year, but he put the Mariners in a deep hole early in a must-win game they eventually lost in extra innings. The 34-year-old perhaps showed his age this season, as he posted a career-high 4.12 ERA. After three years with a strikeout rate at 21 percent, it fell this year to a career-low 17.6 percent. His BB/9 was a three-year high 2.08.

Iwakuma allowed just one run on four hits and two walks with five strikeouts over six innings in a no-decision Monday against Houston.

EDGE Analysis

Iwakuma has been sharp this September, now with four quality starts in five chances and a 22:8 K:BB over 29.1 innings. He appears to have lost his form this season, having allowed a career high 28 home runs in 195.1 innings, but he has managed to give the Mariners chances to win as they try to climb back into the playoff picture in the season's final weeks. The effort lowered Iwakuma's ERA to 3.96; he has yet to allow an ERA of 4.00 or worse in five major league seasons.

Iwakuma (16-12) allowed six runs (five earned) on eight hits and a walk over just 3.1 innings in a loss Tuesday to the Blue Jays.

EDGE Analysis

Iwakuma was riding a three-start quality start streak, but had it snapped as he failed to complete four innings for the third time in his past 11 starts. That inconsistency has led to the worst season of his career. Iwakuma allowed his 27th and 28th homers Tuesday night, the most of his career, and his 4.04 ERA is the worst of his career. If he can't improve it, Iwakuma will post his first season with an ERA above 4.00.

Iwakuma (16-11) gave up a single run on five hits over 6.1 innings even though he walked three with just two strikeouts in Wednesday's win over the Angels.

EDGE Analysis

He's fortunate to have caught the Angels in a slump, as Iwakuma wasn't exactly fooling guys out there, but he kept the ball on the ground well enough to eke out a 2-1 victory. The 35-year-old righty has delivered eight quality starts in his last nine turns, but his lack of strikeouts has to be a concern. His 6.39 K/9 is easily a career low, down more than a full point from his prior career average.

He's still allowing a fair amount of hits, but he's limited the damage in his last two outings - five runs in 13.2 innings. He is 15-11 with a 3.96 ERA, 1.29 WHIP and 130 strikeouts in 179.2 innings this season. His next start will be Wednesday versus the Angels.

Iwakuma (14-10) allowed five runs on six hits and a walk with two strikeouts over just three innings in a loss Monday to the Rangers.

EDGE Analysis

Iwakuma has given up one home run and at least three earned runs in each of his last four starts, and he hasn't struck out more than three batters in any of those outings. His ERA has jumped to 4.01 has a result of this cold streak. As things stand, Iwakuma is in line for his first season with an ERA over 4.00 since coming over to the United States in 2012. He has allowed 24 home runs in 27 starts, and his next home run allowed will tie his career high from 2013 (in 33 starts and 219.2 innings).

Iwakuma (14-9) pitched six quality innings, but took the loss Wednesday versus the Yankees. He allowed three runs on six hits and two walks while striking out three.

EDGE Analysis

After winning his first three starts of the month, Iwakuma has now dropped two straight to match his career high in losses for a single season. The Japanese right-hander now sports a career-worst 3.81 ERA through 25 starts (157 innings) this year. Iwakuma continued to surrender the longball Wednesday, giving up his 23rd homer of the season, and now owns a 1.27 HR/9 -- another career-worst mark. He'll look to end the two-game skid when he toes the rubber for his next start Monday against the Rangers.

Iwakuma will get an extra day of rest in between starts and take the ball Wednesday against the Yankees, MLB.com's Greg Johns reports.

EDGE Analysis

Iwakuma would start Tuesday had the Mariners kept him on normal rest, but the team has decided to give him an extra day in an effort to keep him fresh. Iwakuma has thrown the ball well so far in August, posting a 1.69 ERA and 19:2 K:BB ratio in 26.2 innings over four starts.

Iwakuma (14-8) allowed three runs (two earned) on six hits over seven innings in Thursday's loss to the Angels. He struck out two and walked one.

EDGE Analysis

The Japanese righty landed dueled an effective Matt Shoemaker and came up just short, mostly because of the two runs the Angels got off him in the first inning. Nonetheless, he's made an impressive second-half turnaround -- Iwakuma is 5-2 with a 2.53 ERA and 1.08 WHIP since the All-Star break, representing a giant improvement over his season's first few months. Some pitchers have trouble factoring into the decisions in their starts, but not Iwakuma, who's received a decision in 17 consecutive outings -- he's 13-4 in that span.
