1 year agoLos Angeles Dodgers pitching prospect Jerming Rosario is a 21-year-old starter whom the club signed out of the Dominican Republic in 2018. He spent part of 2021, all of 2022, and the beginning of 2023 in Single-A before being bumped up to High-A on May 10. Rosario throws a low-to-mid-90s fastball that has shown some promise if he can locate it, especially up in the zone. In terms of secondary offerings, he has a curveball that boasts plenty of break, as well as a changeup with deceptive fade. Rosario has struggled with command throughout his career, which has led to his breaker being relatively ineffective. His changeup, on the other hand, has shown some promise, offering a change of pace from his fastball and missing bats out of the zone even if he isn't able to locate it perfectly. The main takeaway from evaluating Rosario is that he certainly has promise but won't get too far if he keeps walking batters and can't improve his control or command. The good news is that Rosario did show progress in the control department during his last outing on June 15. He delivered five scoreless innings, allowing zero hits and just one walk. He struck out eight batters along the way and earned his first win since May 3 when he was still in Single-A.--Andersen Pickard - RotoBaller
