2024 Fantasy Outlook
Kelly's ratios were nearly equivalent to his breakthrough 2022 season, but he took a different path to get there. Last season, Kelly fanned a career best 25.9 percent of batters he faced, but he also walked them at a 9.6 percent clip, the highest mark of his career. However, the 16.3 percent K-BB% was his best in a full season. Kelly didn't change his pitch mix much, other than throwing a slider a bit and it was effective. His changeup was offering chiefly driving the increase in strikeouts. Despite posting strong ratios in 2022, Kelly wasn't trusted since he didn't miss many bats. Fast forward a year and Kelly is no longer a secret after fanning well more than a batter an inning and enjoying a strong playoff run. He's likely going to be drafted around 100 picks earlier this season, which puts him in risky territory, since that assumes Kelly continues to punch out hitters at the same rate. Don't shy away from Kelly, but don't expect a repeat of last season's newfound dominance. Read Past Outlooks
D-backs pick up option
The Diamondbacks exercised Kelly's $7 million club option for 2025 on Saturday, Jon Heyman of the New York Post reports.
ANALYSIS
After missing a four-month chunk of the season due to a shoulder injury, Kelly finished 2024 with a 4.03 ERA and 1.17 WHIP across 73.2 innings over 13 starts. Hopeful for a bounce-back campaign in 2025, the D-backs will keep the 36-year-old righty around to bolster a pitching staff that ranked 27th in the majors with a 4.62 ERA.

2019
This past season may go down as a career year for Kelly, but that's not to say he's unworthy of consideration for 2023. It will just be tough for him to repeat that level of run prevention over 200 innings. When he's on, Kelly can keep hitters guessing with his diverse repertoire -- he throws his four-seamer, changeup, cutter, sinker and curveball all at least 13% of the time. The stuff has not translated to strikeouts since Kelly made the jump from the Korea Baseball Organization years ago (career 20.8 K%), but he limits walks and can induce manageable contact for the defense behind him. Now 34 years old, Kelly may be on the verge of some age-related decline. Add in that he was pitching over his skis last season and Kelly seems likely to be overlooked in many leagues. Be ready to cut bait if the performance craters, but Kelly is very much in the mix to stream in favorable matchups to begin the season.

Latest Fantasy Rumors
Staying put
Arizona has decided not to deal Kelly, reports Jon Heyman of the New York Post.
ANALYSIS
Kelly is having a breakout season, posting a 2.87 ERA, 1.13 WHIP and allowing just seven homers in 125.1 innings. The Mets had previously been rumored to be interested in Kelly as he's under contract for two more seasons. The 33-year-old and Zac Gallen could provide a solid 1-2 punch in the Diamondbacks' rotation for the next couple of seasons.
