The Phillies have designated outfielder Zach Collier for assignment, the team announced via press release. The move was needed to open a 40-man roster spot for catcher Koyie Hill, who was called up to replace Carlos Ruiz (7-day concussion DL) on the active roster.
Collier, a 23-year-old left-handed hitter, was taken by the Phils with the 34th overall pick in the 2008 draft. He was added to the 40-man after the 2012 season to protect him from the Rule 5 draft.
Since that time, Collier has failed to make the jump to Double-A. Over 513 plate appearances in 2013, he put up a .222/.310/.348 line with eight home runs and 17 stolen bases. It has been more of the same this year, as Collier has slashed .228/.307/.316 in 154 trips to the plate, and he has also taken a step back on the bases (he has been caught six times and successfully swiped only three bags).
