- During the season (at the end of each month), I post a review of the top UTR pitchers across each level. At the LoA/HiA levels, Donatella almost made a clean sweep being named the top pitcher. He was bumped out in June by the #2 UTR-OAS Joel Payamps, only because Donatella had a horrible month. He got everything back on track and led all Diamondback minor league pitchers with 13 wins. This was his sophomore season after only pitching 26.2 innings in the rookie leagues in 2015.

- Payamps was released by Rockies on May 2015 and signed by D-Backs the following November. If he would have performed well during the Winter League, the Diamondback risked losing him during the Rule 5 draft this past December. He only pitched 2.2 innings (3 appearances) with Estellas of the Dominican Winter League, surrendering seven runs on 9 hits, facing only facing 16 batters. This will benefit Arizona who won’t leave the young righty unprotected in the future. Payamps struck out almost a quarter of the batters he faced in 2016, a percentage that didn’t dip with a promotion to HiA Visalia. Look for him to make waves in 2017.

- Young is a top draft pick that came out of NCAA powerhouse TCU, where he pitched mainly from the bullpen, but was outstanding as a starter in his final season. That junior season workload didn’t allow the D-Backs to utilize the left-hander in his pro debut, limiting him to only seven innings in seven games. He had an inconsistent 2016 and stumbled a bit after his HiA promotion. The D-Backs should push Young through the higher levels in 2017, and he could quite possibly see his MLB debut in 2018.

- Keller is a very intriguing UTR, making a repeat appearance as an OAS. He possesses size (6’5″- 23o lbs), a mid-90’s fastball with cut & sink that creates a ton of ground balls. To bring this whole package together and advance Keller into the Arizona rotation, is for the lefty to improve his command. Keller doesnt turn 22 until late July, so continue to watch his progress in 2017 with Double-A Mobile.
