Dan Warthen said he asked Francisco Rodriguez to help with Rule 5 pick Pedro Beato's delivery, and the closer obliged on Friday morning.
"I asked him to do that," Warthen said. "I expect that from [Johan] Santana, K-Rod -- especially with the Latin guys. I encourage these guys talking to each other."
As for the technical aspect of Friday's lesson, Warthen added: "Stride length. Straighten out his front leg. He kind of has this 'open' gait and never utilizes his height and his length."
