SF Giants top prospects: No. 5 — LHP Kyle Harrison
Highest Level: High School
Acquired: Draft (2020)
Future-Value Grade: 50
The Giants drafted Kyle Harrison with the 85th overall selection in last summer’s draft but paid him a lucrative $2.5MM signing bonus equivalent to the slot-value of a late first-round pick. While the Giants drafted four players before Harrison, he received the second-highest bonus of the group. Even without a minor-league season, he has already taken substantial steps in the right direction.
Harrison showed excellent ability to mix his pitches at local De La Salle High School with a potential plus curveball, average changeup, and low-90s fastball. His mechanics were somewhat inconsistent, and his arm seemed to get caught behind his body at times. However, he still projected as a potential mid-rotation arm.
Then, over the summer, Harrison bulked up and came into instructs consistently hitting the mid-90s and even touching 97 mph. Given his already advanced feel for his secondary pitches, a jump in velocity could have huge implications for his upside. He still worked primarily from 90-94 mph, but at this point, the Giants are confident he’s the best pitching prospect in the system.
Given his advanced pitchability, fans should expect Harrison to make his full-season debut in 2021. Luckily for the Bay Area native, that should be at San Jose, where Harrison will highlight a pitching staff beside a lineup filled with the Giants’ best prospects.
