Ilia Malinin s brilliant quad axel, along with four more quads packed into a dynamic free skate Saturday night, was enough to lift him past early Kao Miura at Skate America. The 17-year-old American finished with 2807.73 points in his senior Grand Prix debut. That was more than seven points clear of Miura and well ahead of third-place Cha Jun-hwan of South Korea. In the pairs competition, American world champions Alexa Knierim and Brandon Frazier overcame a few mistakes in their free skate to win the opening Grand Prix event of the figure skating season.
