After each appearance, Warthen says he receives an update on Perez�s performance from bullpen catcher Rafael Arroyo, who accompanied Perez to �be a guy that pushes him do his workouts each and every day.� �At times,� Warthen said, �he thinks that Ollie is up-and-down, and his heart isn�t as in it as much as it should be at times. But he feels good, and he�s getting in shape, and he�s working hard, realizing that this is a big year.� Glad they sent someone with him, because i still think not doing that for the WBC was a big mistake. Mildly disturbing though, about his heart and stuff. Pretty much confirms that he needs a lot more guidence and structure than an average pitcher, which isn't necessarily bad, but I don't trust Warthen to be that guy that goes out there and yells at him when he loses focus and walks a guy after he's 0-2 on him. Question is, were he to make the team, could David Wright be that guy?
