A perfect week at home did little to improve the Arizona Wildcats' lot in the ESPN.com/USA Softball Collegiate Top 25.

The UA stayed at No. 19 in the poll, released today, despite going 5-0 in the Hillenbrand Invitational. 

Oklahoma stayed at No. 1, receiving 16 of the 20 first-place votes.

Beside the UA, six other Pac-12 teams appeared in the poll: No. 3 Arizona State, No. 8 Cal, No. 11 Oregon, No. 13 UCLA, No. 17 Stanford and No. 22 Washington.

The 8-2 Wildcats start the Cathedral City Classic in Palm Springs, Calif., on Thursday, against the Sooners.
