Marlie Giles solo home run leads Alabama softball past Duke in WCWS

Catcher Giles hit a clutch, one-out solo home run shot in the sixth inning to put Alabama ahead 2-1. It was Giles' seventh home run of the year and her first since March 29. It was also Giles' first home run back from an injury she sustained vs. Kentucky on March 30 that saw her out of the lineup until May 2.

Before her home run, Giles had collected Alabama's lone RBI on Friday with a double in the first inning. She finished the night going 2-for-3 from the plate with two RBI along with getting a clutch out for Alabama in the third inning when she caught Francesca Frelick stealing second base.

Alabama finished the game with four hits compared with Duke's five. Kristen White and Kali Heivilin each collected a hit, White hitting a single in the second and Heivilin hitting a triple in the fifth. Heivilin nearly homered in the third inning but was robbed at the wall by Duke's D'Auna Jennings.

Kayla Beaver to the rescue for Alabama softball

Freshman Jocelyn Briski got the nod in the circle for the Crimson Tide, making her Women's College World Series debut.

Briski went 4⅓ innings before being pulled after giving up a one-out single in the fourth inning. Briski finished the game giving up five hits and one run, a solo home run in the second inning.

Kayla Beaver entered in relief for Briski in the fourth inning after pitching a complete game vs. UCLA on Thursday. She retired all 11 batters she faced.
