Rest-of-Season Projections
2024 Fantasy Outlook
After being highly touted as a prospect, Kirby showed great promise in his debut season in 2022. The right-hander took his game to another level in his sophomore campaign, shaving his walk rate from 4.1% to a minuscule 2.5%, the lowest among qualified starters. Kirby has already made history multiple times with his strike-throwing; he tossed 24 consecutive strikes at one point as a rookie and now owns the record for the most quality starts with zero walks (11) by a pitcher age 25 or younger. Kirby lowered his WHIP from 1.21 as a rookie to 1.04 last season while adding more than 60 innings to his 2022 total. His five-pitch mix would seem to give him some room for growth in the strikeout department (career 23.5 K%), but until we see that growth, Kirby should probably remain just outside the fantasy ace tier.

Allows three homers in loss
Kirby (3-3) was hit with the loss against the Twins on Wednesday, allowing four runs on four hits and one walk over five innings. He struck out four.
ANALYSIS
Kirby didn't have his best stuff Wednesday, surrendering back-to-back home runs to Carlos Correa and Trevor Larnach in the first inning, along with a third long ball off the bat of Willi Castro in the following frame. The right-hander had not allowed more than one home run in a start coming in and had held opponents to one or fewer runs in each of his previous three outings. On a positive note, Kirby has now gone at least five innings in five consecutive starts, posting a 32:3 K:BB over that stretch.

Not untouchable?
Kirby could be included as part of a package for Shohei Ohtani, speculates Jim Bowden of The Athletic.
ANALYSIS
Kirby, a 2019 first-round pick, owns a 3.43 ERA this season and a 3.41 ERA across 43 career starts. His .266 expected batting average is subpar, but he counters that with excellent control that's evidenced by his 2.4 percent walk rate, which is the best mark among all qualifiers. He's a logically desirable target in the context of an Ohtani blockbuster.

2020
Kirby is an extremely fascinating pitching profile for a few reasons. His primary calling card is his fastball command as he has been incredibly stingy with walks as a pitcher since college. He has 43 walks in 247 innings of professional baseball and walked 50 in 240 innings as a college pitcher at Elon University. He uses that fastball command to fill the strikezone with his fastball as he throws his four-seamer 45% of the time and the league hit .221 against that pitch. That fastball, by velo and movement, aligns him with the likes of Brandon Woodruff, Frankie Montas, Zack Wheeler, and Jameson Taillon according to StatCast. The other part of his profile is the rest of his repertoire is very hittable as every other pitch he threw had an opponents' batting average .266 or higher. Despite that challenge, he won 8 of his 25 starts upon his promotion and still had a good ratios with a stellar 21% K-BB%. If any of his secondary offerings can take a step forward, things could get very interesting for him in a hurry as there were signficant gaps in his actual vs expected batting averages on his cutter, sinker, and slider. Wide awake sleeper!
