NEWARK, Del. -- University of Delaware softball assistant coach Adrienne Clark has announced her resignation to take a similar position at Columbia University.

The Blue Hens went 16-26-3 during the 2007 season and were 22-26 last season.

She was a two-time first team All-CAA selection, a three-time CAA All-Tournament Team selection, and a 2004 NFCA All-Mid Atlantic Region Team honoree.
