Stanford redshirt junior Kristina Vaculik is the Pac-12 Gymnast of the Week after an all-around win and clutch performance on floor in Sunday's tri-meet against Arizona and Sacramento State. She recently talked with Pac-12 Networks' Sarah Kezele about the pressure on her squad to remain undefeated, her experience competing at the 2012 Olympics, and whether she'll root for her native Canada or the U.S. at the upcoming Winter Games.
