Corniell, the Rangers’ top pitching prospect, has been promoted to Triple-A Round Rock following a long recovery from elbow ligament repair. After a 2023 breakout (2.92 ERA, 119 K in 101 2/3 IP) he returned in July 2024, logged four rehab starts in the Arizona Complex League, then dominated six starts at Frisco (0.90 ERA, 20 K, 1 BB in 20 innings, .138 opponents’ average). The move to Round Rock signals a steady climb back toward the big leagues and a tantalizing fantasy arm despite injury risk.

With MLB Pipeline listing him as Texas’s top pitching prospect, Corniell’s path back to Texas could accelerate if he maintains velocity and control. Fantasy managers should track his AAA results and any signs of durability as the Rangers balance his workload with his long-term health plan.
