New York Yankees left-hander Carlos Rodon suffered right hamstring tightness while rehabbing from left elbow surgery, potentially delaying his return to the rotation. The injury occurred during running drills Tuesday, not while pitching, according to manager Aaron Boone. Rodon had been progressing well through his throwing program and was scheduled for a Double-A Somerset rehab start.

Rodon underwent surgery last October to remove a bone spur and loose bodies from his elbow. He had most recently completed live batting practice, throwing three simulated innings and 50 pitches. The 33-year-old was expected to rejoin the Yankees in late April or early May, but this setback could push that timeline back. Boone indicated the team would assess Rodon's condition before determining next steps.

Last season, Rodon went 18-9 with a 3.09 ERA in a career-high 33 starts, made his third All-Star team, and finished sixth in AL Cy Young Award voting. The Yankees were counting on his return to bolster their rotation, making this development particularly concerning for the team's pitching depth.
