Mar 2021 Report

Evaluator: Anthony Franco

Age: 19 yr
Height: 6-1
Weight: 160 lbs
Hits/Throws: R/R
Acquired: 2019 IFA
RuleV: 2023

Physical Description: Listed at 6-1, 160. Lean body with ample remaining physical projection.

Delivery & Mechanics: Vertical arm slot. Gets down mound well with slightly above-average extension, leading to slightly lower than average release height.

Fastball: Sourced Trackman data has average fastball velocity at 90.5 mph with high raw spin (2455 RPM). As one may expect with vertical arm action and high spin, induces plus vertical action. Grade: 50

Curveball: Sourced Trackman data has average curveball velocity at 79.2 mph with above-average raw spin (2668 RPM). Grade: 50

Control and Command: Frame and athleticism lead to command projection. Didn't issue a walk in 10.1 innings in GCL in 2019, his only stateside experience to date. Control: 50 | Command: 50

Overall: An international signee out of the Netherlands, Robberse has all of 10.1 innings of pro ball. There's very little certainty in the profile because of that, but he's an intriguing low-minors sleeper. Robberse has a lean, projectable frame that should allow him to add velocity in the coming seasons. He threw a ton of strikes in his limited pro time, and his Trackman data (raw spin, low release height, vertical life on the fastball) are promising. If he more consistently sits in the mid-90's as he gets stronger, it could be a plus pitch that drives the profile.
