As conference season begins to pick up in NCAA Division I women’s soccer, the signs are beginning to hint at which teams will be contenders in postseason play. As of Oct. 10, Stanford has snatched the top spot in the United Soccer Coaches poll from former No. 1 UCLA. The Cardinal was previously ranked at No. 2 but earned three big points over Colorado last Sunday to improve to 12-1 overall. All-American redshirt senior Andi Sullivan was called up by the U.S. women’s national team on Wednesday for a pair of friendlies against South Korea in October. This is Sullivan’s first call-up since suffering an ACL tear last year.

This season they have allowed not even one goal a game. But it doesn’t stop there, up top South Carolina is is gifted with Savannah McCaskill and Elexa Bahr who each have five goals this season.

The Terps haven’t earned a point since Sept. 29 against the Wisconsin Badgers, who are now No. 4 in conference standings. Maryland sits at No. 13 in the Big Ten and will look to get a big win over the Nittany Lions. Penn State and Rutgers drew to a 0-0 scoreline after double-overtime on Thursday evening. The Nittany Lions haven’t lost since traveling to Ohio State on Sept. 30.
