The Padres have added pitching prospect Jairo Iriarte to the 40-man roster to keep him out of the Rule 5 draft, tweets Jeff Sanders of the San Diego Union-Tribune. In a corresponding transaction, right-hander Reiss Knehr has been outrighted off the roster. San Diego’s 40-man count remains at 34.

Iriarte, a 6’2″ right-hander, had a breakout campaign in 2023. The Venezuela native divided the year across High-A Fort Wayne and Double-A San Antonio. Working mostly as a starter, he pitched to a 3.49 ERA in 90 1/3 innings over 27 appearances. Iriarte fanned almost a third of opposing hitters while working against generally older competition.

The 21-year-old also walked nearly 12% of batters faced. He clearly still needs to develop as a strike-thrower, but his arsenal has impressed evaluators. Baseball America slotted him fifth among San Diego prospects midseason. He would certainly have been selected in the Rule 5, making this an easy call for the front office.

Knehr has spent the past two and a half seasons as a depth starter for the Friars. He has a 5.96 ERA in 48 1/3 big league innings. The Fordham product owns a 5.54 ERA in parts of three Triple-A campaigns. Knehr underwent Tommy John surgery in July and is likely to miss a good portion of the 2024 season.
