Andy Tullis / The BulletinMadras players celebrate a point on their way to defeating Crook County in Prineville on Tuesday night.

PRINEVILLE — Led by two of the top outside hitters in Class 4A, Madras knocked off Crook County in four games Tuesday to kick off the Tri-Valley Conference volleyball season.

Shelby Mauritson paced the White Buffalo offense with 21 kills and Alexis Urbach added 19 of her own as Madras dropped the host Cowgirls 25-17, 21-25, 25-17, 25-20. Setter Elle Renault dished out 33 assists against the eight-time defending state champions and Mauritson added a team-high 13 digs for the Buffs.

“Our two big hitters did a good job of mixing it up,” Madras coach Rhea Cardwell said. “And Elle had several dumps at good times.”

Jennifer Roth led the way for Crook County (0-1 TVC) with 12 kills. Roth, a sophomore, also went 12 of 15 from the service line with one ace. Aspen Christiansen was a perfect 19 of 19 on serves with three aces, and Abby Smith was 13 of 13 with an ace. Smith, the Cowgirls’ sophomore setter, also “passed tremendously,” according to Crook County coach Rosie Honl.

“Our girls really wanted this one,” Cardwell said. “And they kept after it and rode the momentum.”

Madras continues league play Thursday with another road match, this time at Corbett. The White Buffaloes have now won five consecutive contests.

Crook County, which is in its first year as a member of the TVC, is at Molalla next, also on Thursday.
