In his short stint in 2019, young Arano used a couple different looks on his secondary fastballs, split almost evenly between a sinker (16%) and a fourseamer (22%) with the former being used almost exclusively in early counts against LHB. The sinker comes in at 93 mph with below average sink but good armside tail while the fourseamer shows a touch more velocity (93.6) still with some natural sink and excellent tailing action. With such limited use, results were limited as neither pitch tallied any strikeouts or allowed any hits.
Arano’s primary pitch at almost 62% usage, the slider has a bit below-average velocity at 84.8 mph but was responsible for all 7 of Arano’s strikeouts in 2019 and generated an excellent 36.6% whiff rate. While small sample size caveats certainly apply to Arano, these elite whiffs aren’t new as the SwStr% on the slider has been above 20% each of his 3 seasons, with excellent chase (51.9%) rates as well. Showing excellent depth and looking almost like a more gloveside-moving changeup, this would easily qualify as a Money Pitch with a bit more location (34.2% Zone), and with a 63.6% Z-Contact, it seems it could still be effective if Arano can command it in the zone.
