No. 3 Florida Southern, which extended its winning streak to 22-straight matches, will face No. 7 Gannon on Friday in the NCAA semifinals.

For the second-straight match, Florida Southern dropped the opening set.

And for the second time in six days, it didn’t matter.

The Mocs, fresh off a come-from-behind win in the south region final on Saturday, fell behind early against California State-San Bernardino in the NCAA volleyball quarterfinals in Pensacola on Thursday.

After cruising to a win in the second set, third-seeded Florida Southern put itself on the brink with a win in the third set. Trailing the sixth-seeded Coyotes 21-16 in the fourth, the Mocs didn’t fold.

Instead, they rolled, scoring 10 of the final 13 points to win the set, clinch the match in four sets and punch their ticket to the NCAA semifinals against seventh-seeded Gannon (Pa.) today at 6 p.m.

“This team, we said it all year, they’re very level-headed, they never think they’re going to lose,” said Mocs head coach Jill Stephens. “This was a special one. We did not want to be in the fifth set with San Bernardino.”

Florida Southern, which extended its winning streak to 22-straight matches, needed a rally in the fourth set.

Trailing 9-8, San Bernardino used a 7-2 spurt to give itself a lead and some breathing room. An error-prone Southern team couldn’t shake out of its slump as the Coyotes led 21-16.

Nicole Mattson came to the rescue. The junior outside hitter recorded four of the Mocs final five points. Her last kill gave Southern a 25-24 lead. They clinched the final set 26-24 on an attack error by San Bernardino's Moira Murphy.

Mattson finished with a match-best 21 kills to go with 14 digs. Teammate Anna Tovo recorded 18 kills, 12 digs and three service aces, while Bethan Besancenez handed out 50 assists.

“Nicole is so lethal because she can score in so many different ways,” Stephens said. “She is very craft as an attacker but, right after she got blocked, she came up and had a huge kill from the back row.

“We call her ‘cool cat,’ she’s very confident and just wants to win.”

San Bernardino took the first set 25-23, but Florida Southern dominated the second.

The Mocs roared out to a big 17-7 lead and never looked back. Much of that came on a 13-4 run that featured five San Bernardino errors and three Mattson kills.

As poorly as they played in the second, the Coyotes rallied back in the third set and stood even with the Mocs at 20. But that was as close as they’d come as Anna Tovo followed with a kill and a service ace to make it 22-20.

San Bernardino committed an error before Mattson snuck a soft kill over the net and Besancenez clinched the set 25-11 by powering one over against two blockers. The Mocs took the third set 25-20.

Florida Southern walked off the court Thursday expecting a rematch with second-seeded Regis (Colo.), a team they had lost to 3-1 at the Colorado Premier Challenge earlier this season. Instead, they’ll face upstart Gannon after it upset the Rangers 3-0.

“They serve really tough and they played great defense — they had Regis on their heels the whole night,” Stephens said. “I would expect that’s the same thing they try to do to us.”
