EDGE Analysis

Joyce is not on the lineup card for Saturday's game versus Seattle, so it's likely he'll be placed on the injured list regardless of the results. The right-hander left Friday's appearance without getting an out while dealing with hand irritation and numbness in his fingers. Gerardo Reyes has been recalled from Triple-A to take Joyce's place on the roster.
