Stassi (wrist) will join Triple-A Fresno on Tuesday, Angel Verdejo Jr. of the Houston Chronicle reports.
Manager AJ Hinch indicated Stassi will play every other day, so it looks as though the club will play it cautiously with the catcher after suffering a fracture in the spring. It remains to be seen whether he'll stay in the minors or join the major league club once healthy, but he'll likely need a decent length rehab after sitting out six weeks.
