Summary

He recently completed his first bullpen session post-surgery and demonstrated encouraging velocity, with his fastball sitting in the upper-90s and reaching 99 MPH. Expected return is late August 2026. This represents a positive step in his recovery trajectory, though he remains several months away from game action.
