BA Grade/Risk: 45/High
Track Record: While baseball is a global game, few legitimate major league prospects have come from Europe. Robberse, who grew up in The Netherlands, is looking to make a name for himself as a true European major leaguer. After signing for $125,000 during the 2019 international signing period, Robberse blossomed into a legitimate starting pitching prospect. He spent a majority of his 2022 season at High-A Vancouver and made 17 starts for the Canadians before seeing a late-season promotion to Double-A New Hampshire.
Scouting Report: A slight righthander with a long arm action and true three-quarters slot, Robberse mixes three pitches predominantly in his fastball, slider and changeup combination. He sits 89-92 mph on a four-seam fastball that has natural cut and mixes in a low-to-mid-80s slider with moderate sweep. The two pitches account for over 75% of his pitch usage. He shows a mid-to-high-80s changeup to lefthanded hitters that generated high rates of whiffs and chase swings. Robberse lacks power but repeats his delivery well and shows the ability to tunnel both his slider and changeup off his fastball. Overall it's a strong pitch mix with improving feel and command.
The Future: Robberse has the look of a pitchability back-of-the-rotation starter. If Robberse can add strength, and subsequently velocity, he has a chance to crack a big-league rotation.
Scouting Grades: Fastball: 45. Slider: 50. Changeup: 55. Control: 50. -
Track Record: Robberse was a skinny 16-year-old throwing in the mid-80s in the summer of 2018. The next spring, he reached 88 mph before signing with the Blue Jays for $125,000. He went to the United States after signing and touched 90 mph. When the Rookie-level Gulf Coast League started, he was up to 93 mph. He made his full-season debut in 2021, reaching High-A Vancouver as a 19-year-old.
Scouting Report: Robberse is an easy operator with smooth, fluid mechanics. It’s a low-effort delivery with good arm speed, and while Robberse has gotten stronger over the last few years, he still has a lean, lanky build to project more velocity to his 89-94 mph fastball. He shows feel to spin both his hard curveball and mid-80s slider, both average pitches that could still tick up. He throws a firm changeup that isn’t much of a factor yet. Robberse’s walk rate jumped upon his promotion to High-A, but he’s usually a solid strike-thrower with a repeatable delivery.
The Future: While Robberse’s stuff isn’t overpowering, the projection indicators are encouraging, with the pitch mix, control and delivery to remain a starter. He likely returns to High-A to begin 2022 but could be in Double-A as a 20-year-old.

TRACK RECORD: In the summer of 2018, Robberse was a skinny 16-year-old throwing in the mid 80s. The following spring, he reached 88 mph before signing with the Blue Jays for $125,000. After signing, Robberse went to the United States and hit 90 mph. Once the Rookie-level Gulf Coast League started, he was up to 93 mph. Robberse has a host of projection indicators pointing in the right direction, but the 2020 season hampered his development. He stayed in Florida with a group of Venezuelan players the Blue Jays had in a hotel during the shutdown, training there over the summer before heading home prior to instructional league.
SCOUTING REPORT: Robberse pitches with incredible ease of operation, throwing with fluid, easy mechanics. Adding weight and getting stronger helped Robberse's velocity tick up in 2019, and between his remaining physical projection, arm speed and relatively clean delivery, there's probably more velocity coming. He mixes four- and two-seam fastballs with the athleticism to repeat his delivery and shows command of both. He shows a feel for a breaking ball that flashes solid-average and is in the early stages of learning to throw a changeup.
THE FUTURE: There is a wide range of possible outcomes for Robberse. He's a breakout candidate if his stuff continues its upward trend in 2021. -
