The Florida Gators won the first game of the Women's College World Series championship series, defeating the Michigan Wolverines, 3-2, at ASA Hall of Fame Stadium in Oklahoma City, Oklahoma.

Florida, the top-seed in the tournament, and the defending national champions, now leads the best-of-three game series, 1-0, and needs only one more win to become the first team to repeat as national champs since the Arizona Wildcats in the 2006-2007 seasons.

Michigan, the third-seed, needs to win game two on Tuesday night to even the series, and force an if necessary game on Wednesday evening.

The win gives the Gators four wins in as many games in the 2015 WCWS, while the Wolverines saw their 28-game win streak come to an end.

Haeger struck again in bottom half of the third inning, doubling home Nicole Dewitt, to extend the Florida advantage to 3-0.

Michigan cut into the deficit in the top half of the sixth inning, plating two runs, when Abby Ramirez came through with a clutch two-out, two-run single, to trim the Florida lead to 3-2.

The Wolverines threatened again in the top half of the seventh, putting runners at first and third with nobody out, but failed to score, as the Gators hung on for the one-run opening game win.
