Arizona Diamondbacks
2020 Fantasy Outlook
Kelly, who signed with Arizona last December following a four-year stint in the KBO, led the Diamondbacks with 183.1 innings in 2019, though he struggled with consistency, going 13-14 with a 4.42 ERA and 1.32 WHIP across 32 starts. Kelly allowed too much loud contact (9.5 Barrel% and 42.2 Hard%), which, coupled with his flyball tendencies, resulted in a 1.4 HR/9. He also showed noticeable home/away splits, performing much better at home -- likely due in part to Chase Field's humidor. The righty flashed an uptick in velocity in his first four starts in September, resulting in a 1.00 ERA and 9.3 K/9. His final start of the year was not so pretty, but it was a strong finish overall and that should have him pretty well locked into a rotation spot for 2020. Keep an eye on his velocity in spring training, because if Kelly maintains the increased velo, he could be a significant profit earner as a late-round pick. Read Past Outlooks

Gives up one run in win
PArizona Diamondbacks
August 8, 2020
Kelly (2-1) surrendered one run on six hits and struck out four over six innings, earning the win Saturday versus the Padres.
ANALYSIS
Kelly outperformed Padres ace Chris Paddack in the contest. The only blemish on Kelly's line was a Fernando Tatis solo shot in the first inning. The right-handed Kelly has a 2.29 ERA, 0.97 WHIP and 15 strikeouts in 19.2 innings this season. He lines up for his next start Friday at home in a rematch against the Padres.

Stat Review
How does Merrill Kelly compare to other starting pitchers?
This section compares his stats with all starting pitcher seasons from the previous three seasons (minimum 120 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 120 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

2019 Fantasy Outlook
Kelly signed with Arizona and will get a chance to win a spot in the starting rotation after three seasons playing in South Korea's top professional league. An eighth-round draft pick by Tampa Bay, he got as far as Triple-A, where he had a 2.76 ERA and 8.5 K/9 in 2014, before going overseas. Kelly thrived in the KBO with a 3.80 ERA in four seasons while leading the SK Wyverns to the 2017 championship. His 4.09 ERA from 2017 doesn't look great, but it ranked in the top 10 in a hitter-friendly league, and he had a 9.0 K/9 with outstanding control (2.1 BB/9). Kelly says his velocity improved while in South Korea to the low-90s from the high-80s while in Triple-A. He'll be trying to make a unique transition as few players have moved to Major League Baseball from the KOB, and he's also doing so without any major-league experience. He's a fantasy baseball wild card.
