Arizona worked its gameplan to perfection in its first ever appearance in the NCAA women's basketball tournament.

Marte Alexander scored 21 points and Lisa Griffith added 18 as the Wildcats routed Western Kentucky 76-54 Friday night in the first round of the NCAA West Regional at Athens, Ga.

``We tried to exploit them from the very beginning,'' Arizona coach Joan Bonavicini said. ``Our defense picked up its intensity and that takes teams out of their game. We were very fortunate tonight.''

The Wildcats (23-7) advanced to a second-round game against Georgia, a 95-55 winner over Eastern Kentucky.

``We came out knowing what we had to do,'' Alexander said. ``We were all very excited to go to the NCAA tournament for the first time.''
