St Louis Cardinals non-tender former Toronto Blue Jays pitcher, now a free agent

The Blue Jays traded Robberse ahead of the 2023 trade deadline alongside Adam Kloffenstein for Jordan Hicks.

The 23-year old underwent Tommy John surgery in may and will miss the remainder of this season and part of 2026 as well.

The young Netherlands-born righty has generally been a serviceable starter in the minors.

From 2021 to 2024, he tossed 414 1/3 innings, allowing 4.04 earned runs per nine. His 22.5% strikeout rate and 8.9% walk rate in that span were both fairly average numbers.

He also got ground balls on close to half of the balls in play he allowed.

This year, he got out to a rough start, posting a 7.36 ERA over four Triple-A outings.

However, that seems to have been mostly bad luck. His .447 batting average on balls in play and 61.6% strand rate in that small sample were both to the unfortunate side.

Meanwhile, his 24.7% strikeout rate and 46.8% ground ball rate were both strong numbers. His 10.4% walk rate was on the high side but not egregiously so.

Regardless, Robberse is not going to get a chance to correct those numbers, an unfortunate blow, but not a huge deal in the short term.

In the longer term, this will cloud Robberse's path to making it to the majors.

Instead of competing for a role in on a team in spring training, Robberse will be rehabbing from his surgery.

He's currently in his second of three option years. That means 2026 could be his final option year, and he probably won't be fully healthy until midway through that 2026 season.
