The Oregon women’s indoor track and field team ascended to No. 1 in the first regular-season U.S. Track & Field and Cross Country Coaches Association (USTFCCCA) Division I National Team Computer Rankings.

The team rankings are based on a mathematical formula that takes into account national descending orders lists and results from previous seasons. The Oregon women were ranked No. 4 before the season began and the jump in the rankings are likely attributed to the outstanding early season contributions from first-year athletes Jasmine Todd and Sasha Wallace (who weren’t taken into account during the initial No. 4 ranking). Strong performances from Laura Roesler, Phyllis Francis and Jenna Prandini have also helped Oregon’s ranking.

Through two meets, Todd is already the NCAA leader in the long jump (21-0 (6.40 m)) and has the second-fastest 60 meter time (7.20). Wallace’s time of 8.10 in the 60 meter hurdles is the fourth-fastest collegiate time this season.

Oregon is looking for its fifth consecutive NCAA Division 1 indoor championship — a feat that has only been accomplished by LSU’s women during the 1990′s. Rounding out the top five in the women’s rankings are Texas, Texas A&M, Florida and Georgia.

The Oregon men remain No. 3 in the latest rankings. In fact, the entire preseason top five was unchanged. The top five teams, in order, are Arkansas, Florida, Oregon, Wisconsin and Texas A&M.

The Ducks are scheduled to compete this weekend at the UW Invitational in Seattle. Action begins on Friday, Jan. 31 and will continue through Saturday, Feb. 1.
