Libby's Ryggs Johnston was one of a trio David Puig and Cameron Sisk carding three under 68s to lead Arizona State past in-state rival and 36-hole leader Arizona in blustery wind to take an eight-stroke victory at 20-under-par 832.
Their third-round total of 274 was 10-under-par.
“The last two years, we had a chance to win and Oklahoma State beat us both times,” said Arizona State coach Matt Thurmond. “We are so excited to finally hold the trophy.”
The ASU counting scores by Johnston, a freshman, Puig, a freshman from Spain, Sisk, a sophomore from San Diego and the Pac-12 Freshman of the Year in 2019 were completed by a one under 70 from junior Mason Andersen of Chandler, Arizona.
The Sun Devils, who were in third place through 36 holes, made an early move as Puig logged four birdies in his first six holes and Sisk was three-under through two holes with a birdie-eagle start.
“It was huge for our team to have a couple of hot starts,” Sisk said. “It put us in a good position for the rest of the round. I didn’t really know where we were, but I knew it was a big boost for our team and me individually.”
