Texas schools continue to flex their muscle as many of the nation’s top teams prepare to compete in some power-packed Labor Day weekend tournaments.

Defending national champ Byron Nelson (Trophy Club, Texas) last week continued its torrid play by going 8-0 and winning the NorthWest ISD Volleyball Classic. That title came on the heels of winning the Ann Kang Invitational in Hawaii.

Meanwhile, another Texas team, No. 21 Allen (15-1), is hoping to continue its red-hot play in Volleypalooza, a monstrous, 68-team, three-day event in Texas that will draw the likes of Torrey Pines (San Diego), No. 8 Cypress Ranch (Houston), No. 6 Prestonwood Christian (Plano, Texas), Highland Park (Dallas), Lake Travis (Austin, Texas), Grand Oaks (Spring, Texas), and more.

Allen last weekend won the Allen Texas Open, beating Keller (Texas), which makes its debut this week at No. 25. Cypress Ranch (11-0) also is playing well.

Meanwhile, No. 4 Mater Dei (Santa Ana, Calif.), No. 16 Winter Park (Fla.) and No. 22 Cornerstone Christian (San Antonio) this weekend will join a host of Florida state champs and others in the Nike Tournament of Champions Southeast in Gainesville.
