World champions Alexa Knierim and Brandon Frazier are looking to become the first American pairs team to win the prestigious Grand Prix Final. The Americans turned in a brilliant short program Thursday in Turin, Italy. Knierim and Frazier trail their biggest rivals, Riku Miura and Ryuichi Kihara of Japan, by less than half a point heading into Friday’s free skate. Men’s world champion Shoma Uno led a Japanese sweep of the first three spots following his short program with a world-leading 99.99 points.
