Four days after pitching the first perfect game for Missouri in nine years, Chelsea Thomas threw another one against Missouri State.
Thomas didn't give up any hits or walks and struck out 15 of the 18 batters she faced in six innings, setting a new school record for most strikeouts in a non-extra inning game. Her performance led to an 11-0 win for No. 18 Missouri in the Breast Cancer Awareness Tournament at Saint Louis University.
It was the third straight victory for Thomas (3-2) and the seventh straight for Missouri (10-3). Missouri State fell to 3-5.
In 35 innings this season, Thomas has struck out 57 batters while walking only five.
Missouri right fielder Ashley Fleming tripled in the first inning to score shortstop Jenna Marston. The Tigers added three more runs in the third inning when Marston hit a home run and left fielder Marla Schweisberger hit a two-RBI single.
Missouri scored two more runs in the fifth inning and five runs in the sixth to end the game early. Schweisberger was 4-for-4 with six RBI and a run.
Missouri's Karen Snelgrove pitched back-to-back perfect games April 25 and 26, 1991, according to Steven Keers of the Missouri Athletic Department.
In the past five years, no Division 1 softball pitcher has pitched two perfect games in a week period. Georgia's Kate Gaskill pitched a perfect game March 15, 2008, and then combined with a teammate to pitch another perfect game April 23, 2008.
