MORAGA, Calif. — Junior outside hitter Veronica Jones-Perry helped push No. 8 BYU women’s volleyball to a five-set come-from-behind victory (22-25, 20-25, 25-20, 25-23, 15-10) against Saint Mary’s Thursday night at McKeon Pavilion.

"I'm proud of our team's fight tonight," BYU head coach Heather Olmstead said. "Things weren't going well for us, but we just never gave up. Saint Mary's played well and Rob (Browning) does a great job, so we knew his team would be prepared. We had some players step up and execute when it mattered, which was nice to see."

Veronica Jones-Perry led the Cougars with 24 kills to go with 11 digs for a double-double. Lyndie Haddock collected 46 assists and Mary Lake had 15 digs. Cosy Burnett contributed 12 kills and five blocks while Kennedy Redding added nine kills and six blocks. Taylen Ballard had eight kills and four blocks in the win.
