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.

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.

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.

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.

Iwakuma battled neck stiffness Saturday but allowed just three runs on nine hits with no walks and two strikeouts in 5.1 innings in a win at Oakland.

EDGE Analysis

Iwakuma struggled at times -- he allowed the leadoff hitter to reach in five of six innings -- but he limited the damage enough to win his 14th game. He got treatment before the game for neck spams, which affected his pitching. He said his neck was stiff from the third inning on. "I think you could see my body was starting to fly open and my elbow wasn't as high as I wanted it to be," Iwakuma told the Seattle Times. "I got very lucky for the win."
