Auna Janis scored in the 69th minute when Miami keeper Vikki Alonzo dove to intercept a ball into the box, but it glanced off her fingertips and found the foot of Janis, who scored in the open net.
"I'm obviously disappointed with the result, but we played very, very good soccer and had chances to win the game," said Miami coach Tricia Taliaferro. "This was a good learning experience. None us like to lose, but we will remember this when we get into a tough situation, when the game is tight."
Miami heads to California for its longest road trip of the season when it faces second-ranked UCLA Friday evening and San Diego Sunday afternoon at the UCLA Women's Cup.
MISSOURI RECOVERY. After a slow start, Missouri is looking like it could be a Big 12 contender. The Tigers beat previously unbeaten Vanderbilt, 3-0, and Butler, 2-1, to improve its record to 4-2-0.
The top three goal scorers from last season -- junior Kristin Andrighetto, sophomore Alysha Bonnick and junior Michelle Collins -- have yet to find their stride. They have only four goals and one assist between then in six games.
Andrighetto, who led the Tigers in goals (14) and points (37) in 2007, has yet to start because she hasn't passed the Tigers' fitness test for starters.
