The Phillies have a deep starting rotation and don't currently have plans to call up Pedro Martinez.

"We don't have a current plan as of yet what the next step is other than he'll throw a bullpen [Sunday]," Phillies general manager Ruben Amaro Jr. said. "Once we talk to Pedro about the plan, we'll let you know."

Martinez threw 53 pitches in a bullpen session over the weekend as the pitcher attempted to smooth out his deliver from the stretch.
