Yondrei Rojas is one of the more interesting relief prospects in the <a href="https://bluejaysnation.com/">Toronto Blue Jays</a> system.

The right-handed pitcher will be the subject of this week’s Under the Radar Blue Jays’ prospect. Last week, we looked at the <a href="https://bluejaysnation.com/news/under-radar-toronto-blue-jays-prospect-will-robertson">recently called-up Will Robertson</a>.

Rojas signed during the 2021 International Free Agent period out of Venezuela and made his professional debut later that season. With the Dominican Summer League Blue Jays, Rojas had a 2.95 ERA and a 2.74 FIP in 21.1 innings pitched, with a 28.1 K% and a 9.4 BB%.
In 2022, the right-handed pitcher pitched between the Florida Complex League and Single-A. Rojas authored a 4.60 ERA and a 4.51 FIP in the Complex League, and had a 5.40 ERA and a 4.48 FIP with the Dunedin Blue Jays.
Rojas spent the majority of the 2023 season with the D-Jays, where he finished the season with a 5.66 ERA and a 4.88 FIP in 49.1 innings pitched, starting nine of the 16 games he appeared in. He pitched a total of 53 innings with an 18.9 K% and a 9.5 BB%.
In 2024, he spent the entirety of the season with the D-Jays, pitching in relief for all 33 games he appeared in. Although his ERA and FIP were on the high side (both 4.36), Rojas posted a career-best 29.1 K%, as well as a career-worst 11.2 BB%.
This season, Rojas had made the jump to High-A with the Vancouver Canadians. After starting the season on the Injured List, Rojas has a 2.13 ERA and a 2.90 FIP in 12.2 innings pitched, appearing in all 10 of his games as a reliever. Rojas’ K% has taken another jump this season, sitting at 34%, while his BB% has dropped to 9.4%.
Despite standing at just 5’10”, 180 lbs, Rojas’ four-seam fastball sits in the mid-90s, reaching as high as 97 mph. The 22-year-old has three other pitches: an upper-80s cutter, a mid-80s slider, and a mid-80s changeup.
Rojas is a reliever worth monitoring, as he could end up in Double-A sooner rather than later if he continues to post good results with the Canadians.
