Primarily a left fielder, Mayberry Jr. has also seen brief action in center, right and 16 games at first base.
He is also a right-handed source of power in the lineup, as he connected for 15 homers and had an .854 OPS over 267 at-bats last season.
His 2012 season has gotten off to a slow start, but the 28-year-old connected for his fourth homer -- a three-run shot -- in Saturday's loss to the Blue Jays. He hit his fifth homer in the third inning on Sunday
"Just try to play good fundamental baseball," Mayberry Jr. said, when asked what he needs to do to be a contributor to the Phillies' lineup. "Just do what the situation calls for. Have a plan, have an approach and just try to be a tough out.
"My best baseball is definitely ahead of me."
