Stanford women's soccer came close to an undefeated record last season on their route to winning the 2017 national championship, but finished the season at 23-1-0. Not a single men's or women's soccer team finished out 2017-2018 with a perfect season.
This season, there are no undefeated teams (no losses or ties) left in college soccer. The Saint Mary's men's team was the lone undefeated team for a while, until they tied San Diego on Oct. 26. Washington State was the last undefeated women's team until the Cougars loss to Colorado on Oct. 4.
