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. Read Past Outlooks

Kelly (7-9) took the loss Saturday as the Diamondbacks were downed 4-2 by the Cardinals, giving up four runs (one earned) on five hits and three walks over five innings while striking out five.
Arizona errors in the first and third innings -- one of them his own -- cushioned the blow to Kelly's ERA, but the right-hander still needed 96 pitches (56 strikes) to record 15 outs, only the second time in his last nine starts he failed to complete at least six innings. Kelly will carry a 3.93 ERA and 86:31 K:BB through 110 innings into his next outing Thursday, at home against the Brewers.

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 this season's data (min 70 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
