CINCINNATI -- Sean Casey made it official on Friday and will appeal his three-game suspension for his role in the June 5 on-field fracas with Tampa Bay.
His suspension was due to begin on Saturday, when the middle game of the three-game Interleague Series with the Reds is to be played.
The appeal means the Boston first baseman, who will start Friday night's opener at Great American Ball Park, will be able to play all three games against his former team.
The hearing will be on June 23, the same day as Coco Crisp's appeal for his role in the same on-field incident.
Crisp was suspended seven games while Jon Lester finished his five-game suspension on Wednesday before beating Baltimore on Thursday.
