Mental errors and strong pitching led to a 2-1 loss for Missouri Saturday in the second game of the NCAA regional tournament in Columbia.

The game went into the 11^th inning, when DePaul put two runners on base. Missouri catcher Megan Christopher was able to tag out DePaul’s Brittney Yniguez at home. But Christopher lost track of Alex Morocco. As Christopher walked toward the pitcher, eying the runner on second, Morocco rounded third and took advantage of the catcher being out of position.

It was the second win of the day for DePaul. The Blue Demons beat the Indiana Hoosiers in the first game of the day.

Missouri started the tournament with a convincing 12-3, five-inning win over Illinois State, highlighted by homeruns by Ashley Fleming in the four-run second inning and Nicole Hudson in the seven-run third inning. Pitcher Kristin Nottelmann earned the win in that game, increasing her record to 16-1.

Chelsea Thomas threw a strong 10 2/3 innings, giving up five hits and striking out 11, but gets the loss.

The loss to DePaul moves Missouri into the consolation round Saturday night, where they must win in order to continue on en route to the Women’s College World Series.
