Today’s subject is Starlyn Castillo. These articles will mostly be about players I have seen. So, they will be about players from the lower levels of the organization. If you have someone in particular you want to hear about, put the name in the comments section. If I’ve seen enough to warrant a post, I’ll strongly consider it.
This is an open discussion about some of the Phillies’ minor league prospects. Phillies’ talk and other non-prospect discussion should remain in the Open Discussion.
Starlyn Castillo was signed by the Phillies as an international free agent on July 2, 2018 out of the Dominican Republic.
Castillo spent that first summer at the Phillies Dominican Academy on a future services contract. He came stateside after the 2018 season to attend his first Instructs. The 17-year-old RHP saw limited action this summer in his first professional season. He developed a blister on the middle finger on his throwing hand toward the end of XST and was held of GCL action until mid-July.
Castillo made five appearances but exhibited a composure that far exceeded his young age. In his third appearance, he pitched the second, third, and fourth innings of a no hitter. He had a low-to-mid 90s fastball that he complemented with promising secondary pitches. He’ll likely repeat rookie ball with a return to Clearwater or possibly Williamsport.
Castillo was one of the top players to come out of the 2018 international signing period (8th by MLB, 16th by Baseball America). He was signed on July 2nd and received a substantial signing bonus. He has a 6’0, 210 lb frame. (He has put on maybe an inch and 5-7 lbs in the past year.) At 16-years of age, he exhibited a 93-97 mph fastball, a power slider with plus potential, and a developing change up. As with most young pitchers, scouts noted his inconsistencies with his secondary pitches and his command. They were also concerned about his weight. Most Latin ballplayers in their teens are more slightly built. At worst, he was seen as having a future in the bullpen.
I saw Castillo pitch in XST, in his two home GCL appearances, and in 2019 Instructs. I didn’t check for velocity during XST and Instructs, but he was 92-94 in his third GCL appearance. His slider was 87 and his change up was 81-83. I was impressed with his poise and composure. So much so that I even forgot he was just 17-years-old. He was coming off the finger injury, so you have to ignore his pitching line on such a small sample. You really need to see him.
