The Book on John Mayberry
Prospect Info
John Mayberry
Born 12/21/1983
OF, PHI
A big, strong Stanford graduate, John Mayberry Jr is the son of ex-Royal/Blue Jay John Mayberry Sr. He came to the Phillies in Nov 2008 when they traded away former #1 prospect Greg Golson to the Rangers.
A mature prospect with near-MLB ready power, Mayberry had a cup of coffee with the Phils in 2009 while filling in for injuries, but his real arrival is probably late 2010 or 2011. He's a toolsy type with plus-power potential, though it's not there yet, complete with the high strikeouts and inside-pitch vulnerability one might expect. He is best suited to a corner outfield position.
