DENVER -- Marquise Carter scored a career-high 24 points, lifting 11th-seeded Gonzaga to an 86-71 victory over sixth-seeded St. John's on Thursday night to cap a stellar day for the underdogs at the Pepsi Center in the NCAA tournament. The Bulldogs (25-9) were the third lower seed to spring an upset, joining No. 12 Richmond and No. 13 Morehead State. These days, Gonzaga can hardly be considered an underdog, especially with its rich history of tournament upsets. The Bulldogs move on to face third-seeded BYU, the only team that survived a scare on this floor. The Jimmer Fredette-led Cougars knocked off Wofford, 74-66. The Bulldogs used their size and strength to muscle around the Red Storm (21-12), who were back in the tournament for the first time since 2002. Gonzaga outrebounded St. John's by a 43-20 margin.
