Mayberry has yet to make his major league debut after playing the past four seasons in the Rangers organization, reaching as high as Triple-A in 2008. The powerful right-handed hitter hit 16 home runs in 437 at bats (one home run per 27 at bats) with Triple-A Oklahoma City. In his minor league career, Mayberry has averaged one home run every 21 at bats.
The Phillies didn't see Golson fitting into their outfield plans for 2009 and have more speed-type outfielders coming along at the lower levels in the minor league system and deemed Golson expendable. What they lacked was an upper-level prospect with true power and Mayberry fills that void.
"My family is going to be a lot closer to me now, so that's a good thing. If I have to go somewhere, this is a good place to go," Golson told MLB.com after the trade.
Mayberry is the son of former Royals first baseman John Mayberry. The elder Mayberry also played for Houston and Toronto in his 15 year major league career.
If the Phillies are unable to re-sign Pat Burrell, Mayberry will likely compete for the left field job in Spring Training and could wind up as part of a platoon situation if he doesn't win the job outright.
