Estevez (shoulder) threw in a game at the Royals' Arizona complex on Saturday, Joel Penfield of KC Sports Network reports.
Estevez retired four of the five hitters he faced while showing increased velocity, per Penfield. The veteran right-hander is expected to pitch again in Arizona before embarking on a rehab assignment as he works his way back from a right rotator cuff strain. Estevez has been shelved for virtually all of 2026, hitting the injured list April 1 due to a left foot contusion before suffering the shoulder injury during a rehab appearance May 6.
