After a momentum-stifling loss in the third set, the host Deer Valley High boys volleyball team rallied from as much as six points down to take the fourth game for a 25-21, 25-18, 28-30, 25-23 win over Mountain View in this California Interscholastic Federation Northern California Division I semifinal on Thursday.

Deer Valley (42-1), which advances to the 7:30 p.m. final against Archbishop Mitty-San Jose on Saturday at Dublin High, controlled the action through most of the first two sets and held a 19-12 lead in the third set before Mountain View (29-3) began to chip away. The Wolverines' lead melted to 24-23 and when Marcus Lee's attempt to end the match found the net, the Spartans seized momentum and forced a fourth set.

Deer Valley trailed throughout the fourth set and didn't get a lead until a Thio Grigley block made it 22-21. The match-winner came five points later when the Spartans couldn't return a blistering serve from Wolverines setter Derrico Kwa.

"We haven't had our backs against the wall like that much this year," Deer Valley coach Lou Panzella said. "It feels better that it took so much for us to get there."

Jordan Ewert led the Wolverines with 17 kills. Lee added 15 and Kwa provided 49 assists. Mountain View was led by Kurt Dentinger with 17 kills.
