Menzel credited a BYU fan, "in a blue shirt," as if that narrowed down the suspects, for firing up not only him but the entire UC Santa Barbara (15-14) team, playing its first tournament in four seasons.
"I play better mad," Menzel said.
As for BYU (20-9), which spent the entire match trying to find some sort of offensive continuity, the execution did not match the effort.
"All of us, we tried to do too much," said BYU's opposite Robb Stowell, who had a team-high 19 kills. "We tried to play perfect. We got away from what we had been doing all season."
As the match wore on, the Cougars played tighter and tighter. They committed 14 service errors. Meanwhile, Taylor Sander did not enjoy his finest match. The Cougars outside hitter managed just a .163 hitting percentage as the Gauchos targeted the conference Freshman of the Year.
"We put it on him," Menzel said.
In a bit of repeat history, UCSB also upset BYU in 2005, the last time both teams met in tournament play.
"[Menzel's] an incredible athlete," said BYU coach Rob Neilson, who tried unsuccessfully to get his players to relax. "[UCSB] played loose, they played free and they played like they had nothing to lose."
