High-A Vancouver sent Casey (broken hamate) to the Florida Complex League on Tuesday to begin a rehab assignment, Geoff Pontes of Baseball America reports.
He played in just one game at High-A before suffering the injury at the beginning of this season. Casey, who slashed .281/.439/.531 with three home runs and four steals in 23 games as a 22-year-old at Single-A last year, should return sometime in the coming weeks.
