San Francisco Giants: Midseason Top 30 Prospects (Nos. 30-21)

27. SS Dilan Rosario

Age: 18
Current Level: Arizona Rookie League
Acquired: Draft (2019, 6th Round)
Future Value: 35+

It’s often very difficult to project high school shortstops to stick at the position, but Rosario is considered one of the best bets of the 2019 high school draft class.

Carlos Collazo of Baseball America called him “the most polished P.R. prospect in the class.”

Rosario is young for the class. He turned 18 on June 16 and has room to bulk up, which could give him enough power to be a productive everyday player.

The early reviews were that Rosario had quick hands and a smooth swing that barrelled up a lot of balls, but he just lacked the strength to do much damage. However, in his first 10 pro games, he has mashed three home runs while posting a .474 slugging percentage. However, he is struggling to make contact with 20 strikeouts in only 38 at-bats.

Rosario walked away from a USC commitment for a $650,000 signing bonus and he remains my favorite San Francisco Giants pick from Day 2 of this year’s draft, mainly because of his combination of youth and advanced feel defensively. With that said, the bat remains the wild card that will determine his ultimate ceiling.
