The Ducks got off to a hot start, tallying four runs in the first capped by Miranda Elish's two-run RBI single and Lauren Lindvall's RBI single. Nikki Udria's RBI fielder's choice capped a fifth-inning rally that put the game away. Danica Mercado started off the big inning with a bases-loaded RBI double.

Elish's big hit was just the cherry on top of her five inning shutout in which she gave up just one hit and walked three.

Utah 14, BYU - 0 (6 inn., Salt Lake City)

On Saturday, the 11-seeded Utah Utes became the first Pac-12 team to punch its ticket to the Super Regionals after defeating BYU, 14-0. They did so in historic fashion as the Utes recorded their largest margin of victory in an NCAA contest.

Utah senior Anissa Urtez did not go quietly in what could be her last home game, as she recorded 5 RBI going 3-of-4 on the day.

Utah would put up a staggering eight runs in the sixth inning to complete the 14-0 win and claim the Salt Lake City Regional. The Utes will go on to face Washington in a Pac-12 showdown in Super Regionals.

Auburn - 8, California - 2 (Auburn, Alabama)

The Golden Bears saw their season come to an end, falling 8-2 to host Auburn in the regional final. The Tigers got off to a hot start, recording seven runs in the first two innings of play. Cal sophomore Danielle Bowers scored the first run of the day for the Golden Bears as she came home off a wild pitch in the bottom of the third to help chip away at Auburn's 7-1 lead.

At the bottom of the sixth, Cal senior Annie Aldrete grounded out into a double play, but Kylie Reed would cross the plate to score another run, 7-2. Auburn would add an insurance run in the final frame with a solo home run and take the game, 8-2, and the regional title.

Cal finishes its season 32-24 overall.

California - 4, Notre Dame - 3 (Saturday's Resumption, Auburn, Alabama)

California and Notre Dame's elimination game was suspended until Sunday morning due to lightning strikes for a 14 hour delay. The teams resumed in the fifth inning with Cal leading, 4-3. Katie Sutherland-Finch stepped in the circl for Zoe Conley for Cal, and both the Golden Bears and the Fighting Irish dealt strikeouts to keep the game close.

Cal's Kylie Pettis thought otherwise, however, and in the top of the seventh hit a solo shot for an insurance run to put the score at 5-3 in Cal's favor. The Golden Bear defense held court in the bottom of the seventh, as Notre Dame got on first and second base. The third batter flied out for the first out, and then the next batter hit into a double play to end the game.
