The Player of the Week honor is the first of Willis' career, and the 19th all-time selection for the Wildcats.
Four different Wildcats Elizabeth Pickney, Tatum Brown, Lisa Griffith and Willis -- have won the honor this season, marking the first time in a decade that one team has had four different recipients of the Player of the Week award in the same season. Stanford is the only other team ever to accomplish that feat, in 1989-90, with Sonja Henning, Julie Zeilstra, Trisha Stevens and Jennifer Azzi. It is also the first time that Arizona has had four recipients in the same season.
The Wildcats stand at 18-3 overall and 7-2 in Pac-10 play and are tied with Stanford and UCLA for first in the league standings. Arizona plays host to the Washington schools this weekend.
