2007 SIU Edwardsville Cougars softball team

Despite the loss of graduated 1st Team All-American and GLVC Player of the Year Alicia DeShasier, good things were expected of the Cougars. Thirteen players returned from the 52–11 2006 squad that had played in the Division II Women's College World Series, including 3rd Team All-American and 1st team All-GLCV pitcher Sabra McCune and 1st team All-GLCV shortstop Kaeleigh Rousey, along with All-GLVC 2nd team first baseman Emily Lenart, plus All-GLVC honorable mentions pitcher Kaitlin Colosimo and catcher Libby Lenart.[5]

The Cougars were the No. 5-ranked team in the NFCA/NCAA Division II preseason coaches poll.[6]

The season began with the Cougars winning three of five games at the West Georgia Tournament, with both losses to nationally-ranked teams. They then won both ends of a doubleheader at Lincoln before going back South to win twelve of thirteen of games at the Rebel Spring Games in Kissimmee, Florida, losing only to St. Cloud State. The GLVC schedule started with a Cougars' loss in the first half of a doubleheader at Kentucky Wesleyan. The loss was followed by a seven-game win streak (five in-conference) before SIUE lost one of two at Wisconsin–Parkside and two at eventual GLVC co-champion Lewis. They followed that up with nine wins in a row before dropping one at Missouri–Rolla, then closing out the GLVC schedule with four more wins.

The regular season ended with an overall record of 37–8 and a GLVC record of 19–5, which tied Lewis for the conference championship.

The Cougars entered the double-elimination Great Lakes Valley Conference at EastSide Centre in East Peoria, Illinois as the #2 seed.

SIUE beat St. Joseph's in the opening round, Wisconsin–Parkside in the quarterfinals, and top seed Lewis in the first semifinal. After Lewis defeated Missouri–Rolla in the second semifinal, the Cougars won the Final to earn the GLVS's automatic bid to the NCAA Division II Tournament.[11]

The Cougars were the #3 seed at the Great Lakes Regional, hosted by top-seeded Lewis. After SIUE beat Shepherd in the first round, Kaitlin Colosimo pitched her second no-hitter of the season against Wayne State in the quarterfinals. SIUE then bested 4th seed Ferris State in the first semifinal. The regional final matched the Cougars with Grand Valley State, which had won four elimination games after falling to Wayne State in the first round. SIUE scored six runs in the first inning and went on to win the final 10–1 in five innings and advance to the Division II Women's College World Series.[12]

SIUE arrived at the Division II Women's College World Series at Firestone Stadium in Akron, Ohio on a 12-game winning streak. The Cougars continued their winning ways by downing Florida Southern in the opening round and Cal St. Stanislaus in the quarterfinals. In the first semifinal, Kaitlin Colosimo tossed her third no-hitter of the season against the defending champion and top-seeded Lock Haven Bald Eagles. Lock Haven came back to win the elimination bracket semifinal and set up the final. Lock Haven scored one run in the third inning. The Cougars tied in the top half of the fourth only to have the Bald Eagles go back on top with a run in the bottom of the inning. SIUE once more tied the score in the sixth, and the game evolved into a pitching duel between Lock Haven's Kristin Erb and Kaitlin Colosimo, pitching in relief. The Cougars finally managed to score in the top of the twelfth inning, then held on to win the 2007 NCAA Division II Softball Championship.[12][13]
