The Yankees designated Wilkin De La Rosa for release or assignment Thursday.

The 25-year-old left-hander, who is 2-4 with a 5.33 ERA in 36 games (including eight starts) for Trenton this season, was dropped from the 40-man roster to make room for fellow left-hander Steve Garrison, who the Yankees claimed off waivers from San Diego.
