No. 18 Sierra Vista Buena (7-3) at No. 15 Yuma Catholic (7-3)
Buena's James Lesueur (7) sheds the arms of Ironwood Ridge's Jacob Knauer (3) on sweep in the first quarter of their 5A Sonoran Region game, Sierra Vista, Ariz., October 30, 2026.
Location: 2100 W. 28th St., Yuma
Notable: One of the most intriguing games for any Southern Arizona team this week, No. 18 Buena’s lengthy trip to No. 15 Yuma Catholic pits the run-heavy, misdirection-based Colts against a smart, balanced Shamrocks team in the first round of the 5A playoffs. Buena won the region title on Friday night for the first time since 1978 after a 5-1 region record and a head-to-head win over Marana on Sept. 25. They rolled No. 24 Ironwood Ridge 45-10 on a cold, wet night in Sierra Vista, leaving little doubt about their playoff case. The Colts start their playoff journey with a 5.5-hour drive to a hostile environment in Yuma against a 7-3 Shamrocks team whose only losses are to three 5A playoff teams ranked No. 16 or above.

No. 17 Phoenix Sunnyslope (7-3) at No. 16 Marana (7-3)
Marana's Jeffrey Smith III (3) puts the finishing touch on Yuma Catholic's Jaden Johnson (6) ending his sweep in the third quarter of their game, Tucson, Ariz., Sept. 11, 2026.
Location: 12000 W. Emigh Road
Notable: Just one of two local games in Tucson in the first-round affairs this week, No. 16 Marana squeaked into the final host spot in the 5A bracket. Despite losing the 5A Sonoran Region to Buena, breaking a four-year region title streak for the Tigers, Marana is the highest-ranked 5A Southern Arizona team not named Desert View. Marana has faced six playoff teams in the regular season to Sunnyslope’s four, but the Vikings most notably gave 5A No. 3 seed Notre Dame Prep a run for their money, falling 30-29 on Sept. 4, the highest-seeded opponent across both teams’ schedules. Kickoff is set for 7 p.m. Friday in Marana.
