Alabama softball got off to a hot start against Tennessee on Sunday.

The No. 14 Crimson Tide (37-18) took an early 4-0 lead over the Lady Vols courtesy of a grand slam by Riley Valentine, who took Payton Gottshall's pitch deep over the left-field fence in the winner-take-all Game 3 of their super regionals matchup.

Alabama is also taking its 4-0 lead into the weather delay, as play stopped in Knoxville, Tennessee, due to rain.

The Crimson Tide upset the Lady Vols on Saturday night after a wild 14-inning game that ended in walk-off fashion by Kristen White, keeping Alabama's Women's College World Series hopes alive after Tennessee won game one of the series 3-2.

Alabama went 1-2 in games against the Lady Vols during the regular season, with Tennessee later winning the postseason SEC Tournament.
