Manager Pete Mackanin said he is not yet ready to commit to anyone as his starting catcher, the Allentown Morning Call reports.
Rupp earned the majority of the playing time at catcher for the Phillies toward the end of last season. Things really picked up for him in August when he hit seven of his nine home runs and posted a 1.086 OPS in 66 plate appearances. He likely enters camp with a slight advantage over Carlos Ruiz for the starting job.
