Outfielder Joey Rickard is joining catcher Luke Maile in hurdling high-Class A Charlotte.
Rickard is also one of 26 players who have a nameplate hanging in Montgomery's clubhouse today for an exhibition game against the Rays.
The official Opening Day roster won't be set until next week, the Rays say. The Biscuits begin the season at home Thursday against Birmingham.
Rickard, part of Arizona's College World Series championship team in 2012, hit .270 for the low-A Bowling Green Hot Rods.
