George Kirby exits after five solid innings

He was denied the win after the bullpen faltered in the late innings. Kirby allowed just five hits — all of them singles — while walking one and striking out three. It was a nice bounceback outing for Kirby after he was crushed for seven runs, including four homers, in his last outing against the Rangers. He lowered his ERA to 3.76 with the win, and barring a last-minute trade, he lines up to face the Rays in his next start on Saturday.

Passan adds that the sense is that Kirby is available and could be moved prior to Monday’s deadline. He also notes that Seattle has been listening to offer for Emerson Hancock and Luis Castillo. The Mariners have top prospect Kade Anderson knocking on the door of the majors and figure to move at least one, if not more, of their current rotation members. Kirby would net the largest return in any potential trade package, despite holding a pedestrian 3.98 ERA across 120 innings this season.

Kirby’s velocity dipped quickly today; he averaged 96.9 mph in the first but was down to 95.7 mph in the second and 94.9 mph in the fourth. That’s well off his season average of 96.6 mph, and he gave up more runs today than in his previous four starts combined. It’s the third time in his career that he’s given up four homers; it also happened once in 2022 and once in 2023. Oddly enough, in all three of those starts, he gave up exactly seven runs in between four and 4 2/3 innings. He fell to 8-9 with a 3.98 ERA in advance of a start against the Twins.

He struck out six. He threw just 80 pitches to get his 18 outs, and it seems like he still would have had something in the tank for the seventh. However, the Mariners pulled him with a 1-0 lead. It wound up working out just fine, as Nick Davila pitched a perfect top of the seventh, and the Mariners put the game away with six runs in the bottom of the inning. Kirby is 8-8 with a 3.57 ERA. He’s fanned 45 in 42 innings since the beginning of June after totaling 59 strikeouts over his first 74 innings. He’ll likely make his next start next Monday in Texas.

Kirby struck out seven and didn’t walk anyone. He allowed a solo homer to Kyle Stowers but pitched well enough to win. The right-hander stumbled a bit from mid-May through mid-June, but he’s been excellent over his past three outings. Kirby has the worst K-BB% of his career this season but has offset it somewhat by inducing more grounders than in the past. This was his final start of the first half. The Mariners host the Giants coming out of the All-Star break.

Kirby struck out seven and allowed no runs over the final five innings of his second eight-inning start of the year. He’s turned in four straight quality starts while trading four-seamers for sinkers of late. That’s especially been the case his last two starts, both of which were wins. With the Mariners having Wednesday and Monday off, Kirby might not start again until next Tuesday. Or it’s possible he’ll be part of a piggyback tandem on Sunday.

We need to come up with a better term than piggybacking. Seriously. Gilbert takes the ball for a traditional start with Hancock doing the same for Sunday’s series finale. The decision pushes George Kirby back to Monday’s opener against the Angels. The whole Mariners rotation situation is challenging to understand and remains a massive headache for fantasy managers. There have to be some changes coming from a personnel standpoint after next month’s All-Star break because this seems too chaotic to work as a strategic approach for an extended period.

It wasn’t a particularly easy effort tonight, as Kirby allowed eight hits. Still, they accounted for only 10 total bases between them, and Kirby was good about spreading them around. He was 0-5 with a 6.27 ERA in his previous six starts, though the two before this one, both against Baltimore, were already improvements. He’s 6-7 with a 3.94 ERA overall. With the Mariners planning to throw both Logan Gilbert and Emerson Hancock on Saturday, Kirby should start against Sunday against the Guardians.

That’s the same line he had in losing to the Orioles in Baltimore last week. It makes four times this season that Kirby has turned in a quality start and lost anyway. That’s the most quality-start losses in MLB, and Dustin May and Yoshinobu Yamamoto are the only other pitchers with three such games. Kirby will face the Pirates in Pittsburgh next time out.

There’s a lot to unpack here. According to Mariners general manager Justin Hollander, it was a unanimous decision by all six starters — Logan Gilbert, George Kirby, Bryan Woo, Emerson Hancock, Bryce Miller and Luis Castillo — to move to a schedule where each pitcher will rotate through and have piggyback days. Ironically, the arrangement will begin with Castillo piggybacking out of the bullpen with Miller during Friday’s series opener against the Red Sox. The decision will have a significant fantasy impact simply by reducing the overall volume for each starter over the next few weeks. The unorthodox arrangement feels like a temporary stopgap solution until the arrival of top prospects Kade Anderson and Ryan Sloan later this summer ultimately forces Seattle to move on from at least one of their veteran arms.
