Joseph was the biggest surprise of the season after joining the team in May. He finished third among National League rookies in homers and was just the third rookie in 45 seasons to hit 20 or more home runs. Joseph produced well in a platoon with Ryan Howard as the Phillies became the first team in baseball history to have two first basemen hit 20 or more homers in the same season. With Howard's departure, the Phils will likely find Joseph a new platoon partner this winter.
