DeSclafani (ankle) allowed three hits and struck out three over three scoreless innings in a rehab start for Triple-A Sacramento on Saturday.
DeSclafani was excellent in his first game action since April 21. The right-hander still isn't eligible to come off the 60-day injured list until late June, so he's likely to make another start or two with Sacaramento to build his pitch count back up before he rejoins the Giants' roster.
