Kumar Rocker, the Texas Rangers' top pitching prospect, faced challenges during a 4-0 defeat against the Toronto Blue Jays, throwing only three innings. His fastball lacked its usual velocity and command, resulting in five baserunners and one earned run. Despite these issues, manager Bruce Bochy noted Rocker's composure under pressure.

Rocker pointed out his struggle with command, particularly against the Blue Jays' skills compared to previous opponents. He aims to improve with practice and remain resilient as he adapts to major league competition.
