Game of the Day

Alabama seemed on its way to a 1-0 victory until Texas A&M's Tori Vidales tied it up and forced the first extra-inning game of the tournament. It was the first hit of the day by the Aggies.
Vidales took another ball to the warning track in the bottom of the ninth, but Alabama's Bailey Hemphill hit her second home run of the tournament, a solo shot in the 10th, to give the Crimson Tide the lead.

Alexis Osorio made sure A&M didn't rally again and Alabama advanced to the semifinal round.

Player of the Day

Alabama junior Alexis Osorio had a perfect game going into the fifth inning before she issued her first walk. She kept a no-hitter through six innings before giving up the home run that allowed Texas A&M to tie the game in the bottom of the seventh.

The riseball specialist from Riverside, California, struck out the next batter, walked the one after that, and then settled down to retire 10 of the final 11 Aggies she faced, with the only hit coming on a bloop single.

Osorio struck out 15 batters while walking four and holding A&M to only two hits in 10 innings. She threw 94 strikes in 153 pitches, and threw first-pitch strikes to nine of the 10 batters she faced in extra innings.

Play of the Day

Kentucky started getting to Auburn in the top of the sixth inning of a scoreless game. Katie Reed singled, but was called out for leaving first base early. The Wildcats kept pressing: Bailey Vick and Brooklyn Hinz followed with singles to bring up slugger Abbey Cheek, who had two home runs on Wednesday.

Cheek grounded to Auburn first baseman Kendall Veach, who threw to shortstop Haley Fagan to get the lead out at second. Fagan immediately threw back to Veach for the double play at first to end the inning.

The double play was 45th for Auburn, which leads the nation in that category. If Auburn is able to achieve its goal of winning the SEC Tournament for a third straight year, that play will be a key moment in the run.

Biggest Surprise

Ole Miss is scrappy. And game. The Rebels also were swept at Florida this season and were shut out in every game.

That didn't matter to Ole Miss, especially pitcher Kaitlin Lee, who declared after the Rebels defeated Mississippi State in their opening game of the SEC Tournament that she wanted the Gators again. She got them on Thursday and embraced the opportunity, pitching Ole Miss to a huge upset of the nation's top-ranked team.

"Not even arguably, they're going to be probably the No. 1 seed in the NCAA Tournament," Ole Miss coach Mike Smith said. "What a great day to be a Rebel right now. We are so excited for this program. That's a defining moment in our program."

Florida is one of a few teams in contention for that overall No. 1 seed in the NCAA Tournament, which will be revealed when the 64-team field is announced on Sunday night. And if the loss to Ole Miss happens to knock the Gators down a notch or two from the top spot, that's just fine with Lee.

"If anybody was going to do it, I'd want it to be me," she said.

Quote of the Day

We didn't come in here to lose 2-0 and sandbag a game. We just didn't play very well.... It's the same style of ball that we've been playing all year long, and it's frustrating as heck in a lot of ways to watch us come out and play offense sometimes. - Florida coach Tim Walton
