The Biscuits have three "traitors" in their midst.
Pitchers Dylan Floro, Jimmy Patterson and Jake Thompson, who each have lockers in Montgomery's clubhouse (and a Biscuits uniform hanging in front of it), will play against the Biscuits today.
They'll be in Tampa Bay uniforms for the exhibition game at Riverwalk Stadium.
Also, infielder Hector Guevara, who played for the Biscuits last year, will be on the Rays' bench.
The Rays brought six more minor league position players on the trip to augment their roster: catchers Justin O'Conner and Maxx Tissenbaum, infielders Tommy Coyle and Patrick Leonard, and outfielders Kes Carter and Marty Gantt.
