TAMPA – Kenshyra Jackon went deep twice and Lee Ann Spivey hit a grand slam as USF tied a single-game program record with four homers in a 12-1 win over Massachusetts on Friday night.

Spivey's big hit powered USF to an eight-run fourth inning and Kourtney Salvarola also homered in the Bulls' seventh consecutive victory.

The Bulls (13-10) wound up with six homers on the first day of the USF Under Armour Showcase. Stephanie Medina and Monica Santos each left the yard in USF's 5-3 win over South Carolina earlier Friday afternoon.

“Anytime you can put the pressure on the opposing pitching staff and the defense they're going to throw differently. I thought they had to throw to us tonight,” head coach Ken Eriksen said.

Sara Nevins (6-4) earned a win in both games of the doubleheader and she made history in the rout of UMass. The junior left-hander fanned four batters and became only the third Bull to pass the 600-strikeout mark. Current USF assistant coach Monica Triner owns the program record with 641 strikeouts followed by Leigh Ann Ellis (633).

“That's pretty special stuff,” Eriksen said. “She's a special talent. We hope that she's got 600 more in her in the next year and a half.”

UMass got the scoring started in the first and the Bulls' power surge continued in the bottom half of the inning. Jackson hit a two-run over off the light pole in left-center field and Salvarola followed with a solo shot to left field.

Jackson went deep again in the third inning when she hit a 2-1 pitch over the 230-foot sign in center field for her team-leading fifth homer of the season.

Jackson's fourth RBI of the game sparked the eight-run fourth inning for the Bulls. Jackson hit a sacrifice fly with the bases loaded and Spivey posted USF's fourth homer of the game two batters later with a grand slam to right-center field.

Allie Patierno capped off the scoring in the fourth with a three-run double to right-center field.
