Marson's .433 on-base percentage not only led the Phillies organization, it also led the Eastern League and all Double-A circuits in 2008. His OBP also ranked sixth among full-season hitters.
Scouting report: An athletic backstop who can hit for average and knows how to get on base. He has some extra-base power, but it's not a strength. His quick release and accurate arm enable him to throw runners out. Also has off-the-charts makeup and handles a staff well.
Upside potential: Everyday catcher in the big leagues.
They said it: "I saw him when he was a rookie. When he first signed, he was 17 years old out of Arizona. I liked him then and he's going to be a good player. He's got big hands and he can throw and he can handle the mitt. There's no reason why he can't be a good catcher." -- Phillies manager Charlie Manuel
He said it: "It was great for me to be around the guys and see how they go about their business in a pennant race and what they do every day and how they prepare -- everything like that. Just watching guys play helps me a lot." -- Marson on his big-league callup
