No. 10 Oro Valley Ironwood Ridge pulled off the only upset in the first round of the Division II state playoffs on Tuesday. The Nighthawks defeated No. 7 Gilbert Williams Field 5-1 to move on to the quarterfinal round to be played next Tuesday.

All other seeds held form as No. 1 Tucson Catalina Foothills, No. 3 Tucson Salpointe and No. 6 Nogales won their team matches.  No. 2 Phoenix Shadow Mountain defeated No. 15 Canyon del Oro 7-2.

Ironwood Ridge will travel to Shadow Mountain next week. Catalina Foothills will host No. 8 Glendale Deer Valley and Salpointe will host Nogales which means one team from Southern Arizona is guaranteed a semifinal spot.
