2023 Fantasy Outlook
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.

Hit hard in San Diego
Kirby (5-5) took the loss Wednesday, allowing five runs on 11 hits over 3.2 innings against the Padres. He struck out three.
ANALYSIS
It was a rough outing for Kirby after he allowed just three hits in eight scoreless innings in his last outing against the Yankees. The 25-year-old right-hander has a 5.79 ERA over his last four starts after pitching to a 2.45 mark in his first eight outings. Overall, Kirby's ERA is up to 3.50 with a 1.11 WHIP and a still outstanding 61:6 K:BB through 74.2 innings this season. He'll look to get back on track in his next outing, currently lined up for next week against the Marlins.

Past Fantasy Outlooks

2020
At this point, Kirby seems like a near finished product by pitching prospect standards, with the main question mark being durability. He regularly went seven or eight days in between starts last year and missed three weeks in May and and another four weeks in July with shoulder/arm issues. All told, the 6-foot-4 righty logged a 2.53 ERA, 1.08 WHIP and 80:15 K:BB in 67.2 innings (15 starts) across High-A and Double-A. He has always had some of the best command and control in the minors, and Kirby now boasts a monster mid-to-high 90s fastball with good life and three secondary offerings with upside -- his plus upper-80s slider is currently his best offspeed pitch. It's easy to see Kirby maxing out as the Mariners' best pitcher and a true frontline arm if he can start pushing up to 150-plus innings, but just getting to 120-plus innings would be an accomplishment in 2022.
