10/14/17 AFL Notes

Kirby Bellow (LHP) Diamondbacks – Bellow is a lefty who stands on the far right side of the rubber (hitter’s perspective) and pounds the opposite side of the plate with fastballs and curveballs. He was extremely predictable but effective nonetheless. Bellow’s fastball was mostly 90-91 but one touched 95. His curveball was high 70s and is probably his best pitch. It was generating a lot of swing and miss. When batters were able to make contact, it resulted in weak ground balls. He sparingly used a changeup around 83 as a weapon against right-handed hitters. His arm angle looks really tough on lefties. Curiosity got me, and I looked up his platoon splits. Last season in a 39 2/3 inning sample at AA-Jackson, RHH were held to a .654 ops and LHH were utterly dominated. They only had two hits in 61 plate appearances, resulting in a minuscule .098 ops. Bellow should excel as a LOOGY with the upside of a more conventional middle reliever.

(11/26 Edit – I learned that Bellow’s breaker is actually a slider not a curve as I wrote above.)

Dean Deetz (RHP) Astros – I really liked Deetz’s three-pitch mix. It’s definitely worthy of a major league pen. His fastball sat 95-96 and touched 98, although it has been somewhat hittable in my viewings. His 83-85 slider had hefty two plane break, but his command of the pitch waivered. His change was 86-87, and he could spot it to both sides of the plate. Overall, the stuff was impressive, but the command was worrisome. I think Deetz a guy who could thrive in a middle relief role. I also think he’s a guy who could cause your favorite team’s fanbase a lot of stress in a high-leverage role, resulting in a myriad of prematurely balding heads.
