At 22, he's the NCAA and U.S. national champion at 1,500 meters, with an eye on Olympic gold this summer. Centrowitz (Broadneck High) took the bronze at the 2011 world championships, becoming the youngest American to medal in that race. A seven-time All-American, he was The Sun's 2007 Male Athlete of the Year, running the third-fastest two-mile time in schoolboy history.
