2026 Fantasy Outlook
Kelly had a successful return from his shortened 2024 season, resuming his previous levels of production while pitching for both Arizona and Texas last season. Kelly is an unusual pitcher in this day and age because his most frequently used pitch is his change-up, but he throws five other pitches as well. What Kelly lacks in velocity he makes up for in command of that deep arsenal of pitches, and looks to set up hitters for that change-up by keeping them off-balance throughout the count. Home runs have been an issue for him nearly every season due to his lack of velocity, but the lack of walks helps offset some of that damage. While Kelly isn't shiny, he has won double-digit games in three of the past four seasons. Kelly's ERA since the start of the 2021 season is better than the likes of Cease, Gallen, Ryan, Taillon and Pivetta over the same period of time, while he ranks 19th in innings worked despite the time missed in 2024 with the shoulder problems. Kelly re-signed with Arizona during the offseason, providing him a soft and familiar landing for fantasy managers. Read Past Outlooks
Signed a two-year, $40 million contract with the Diamondbacks in December of 2025. Contract includes $500,000 trade-assignment bonus and $12 million vesting option for 2028 with 170 innings pitched in 2027 or $14 million vesting option for 2028 with 185 innings pitched in 2027.
Hit hard in loss
Kelly (5-4) allowed seven runs on six hits, three walks and a hit batsman while striking out four over five innings to take the loss versus the Nationals on Friday.
Analysis
Kelly had a strong May, but his first start in June was a dud. He allowed three home runs, which accounted for four of the seven runs on his line in his first loss since May 3 versus the Cubs. Kelly is now at a 5.71 ERA, 1.49 WHIP and 37:25 K:BB through 58.1 innings over 10 starts this season. His next start is projected to be on the road versus the Marlins.

Before an early shoulder injury sidelined Kelly from mid-April to August, the right-hander was headed for a second consecutive impressive season, posting a 2.19 ERA over four starts. He had less success (4.96 ERA) following his return, but most of the damage was in August, and Kelly was back on form in September. Kelly finished with a greater HR/9 and struck out fewer batters in 2024, but when a pitcher misses four months, one should resist making judgments based on ratios/results and instead focus on the injury, which altered his pitch mix. Kelly threw more cutters and changeups than four-seamers for the first time in his career; however, he pitched well when healthy in April and September, putting him on a path for a normal winter of preparation. The Diamondbacks have confidence that the 36-year-old will return to his 2023 iteration (3.29 ERA, 9.5 K/9) and picked up his option.

NYM could look at him
The Mets could be interested in signing Kelly, according to Will Sammon of The Athletic.
Analysis
It's unclear if both parties have started talking, but Kelly would fit as a potential upgrade for the rotation if the Mets decide to look at other options instead of the top trio of Ranger Suarez, Framber Valdez and Tatsuya Imai. Kelly had a 3.52 ERA in 32 regular-season starts in 2025.
