Jack O’Connor is UCLA’s battle-tested, comeback-story righty with a sneaky effective relief profile
In the 2025 season, Jack O’Connor posted a 1.67 ERA over 27.0 innings with 18 strikeouts, 6 walks, and a .212 opponent average, then followed with a tougher 2026 season (3.52 ERA in 15.1 innings across 20 appearances). He stands out as a resilient, pitch-to-contact bullpen arm whose biggest edge is poise: after Tommy John surgery and another arm procedure, he earned high-leverage trust in UCLA’s postseason run and was used as a setup man. The strikeout total isn’t loud, but the competitiveness and durability story absolutely is.
