Kirby allowed two runs on five hits and five walks while striking out five over 4.1 innings in a no-decision versus the Angels on Wednesday.

Kirby's five walks were a season high, and it underscores his step back in the command department this season. The right-hander has issued 44 walks this year, already 15 more than in any other campaign of his career, though his 2.3 BB/9 is still pretty good in the general context of the majors. The walk rate has been creeping up lately -- he's issued 19 free passes over 49.2 frames since the start of August. Through 169.2 innings this season, Kirby has a 4.24 ERA, 1.39 WHIP and 143 strikeouts. His next start is projected to be at home versus the Astros.

Kirby allowed four runs on nine hits and two walks while striking out five over six innings in a no-decision versus the Athletics on Friday.

Kirby has given up at least four runs in five of his last six starts, yielding a total of 25 runs (24 earned) over his last 33.1 innings. He was able to avoid the loss since he left with the game tied, but it's been an unimpressive end to the year for the right-hander. Kirby is at a 4.25 ERA, 1.36 WHIP and 138:39 K:BB through 165.1 innings over 28 starts. His next outing is projected to come on the road versus the Angels.

Kirby (9-11) allowed four runs (three earned) on seven hits and a walk while striking out five over 6.2 innings to take the loss Saturday versus the Athletics.

Kirby has now allowed at least four runs in four of his last five starts, making him somewhat fortunate to have a 1-2 record in that span. The right-hander gave up all of the runs between the second and fourth innings Saturday, and the Mariners' offense gave him nearly nothing in terms of support. For the year, Kirby is now at a 4.18 ERA, 1.34 WHIP and 133:37 K:BB across 159.1 innings through 27 starts. His next start is projected to be a rematch with the Athletics in Sacramento.

Kirby took a no-decision against the Red Sox on Monday, allowing five runs on seven hits and two walks in five innings. He struck out two.

The ball was flying around Fenway Park on Monday early and often, and Kirby was tagged for four extra-base hits on the evening. The right-hander has been a hit-or-miss fantasy option since coming back from the All-Star break, giving up at least five runs in four of his last eight outings while yielding less than two in the other half. He'll be aiming for some consistency in a favorable home matchup with the Athletics this weekend, carrying a 4.19 ERA, 1.35 WHIP and 128:36 K:BB over 152.2 innings.

Kirby (9-10) earned the win Tuesday over the Phillies, allowing one run on six hits and a walk across 7.2 innings. He struck out nine.

It was an excellent bounce-back outing from Kirby, who had given up 11 runs across eight innings in his previous two starts. The right-hander held Philadelphia to a lone second-inning run and needed just 92 pitches to work into the eighth inning. The 28-year-old Kirby lowered his ERA to 4.02 on the season with a 1.33 WHIP and 126:34 K:BB across 25 starts (147.2 innings) this season. He's currently lined up to face the Red Sox on the road his next time out.
