Tampa MMA fighter takes his shot at UFC's biggest stage

Elite fighters say their next fight is always the most important fight. But for Tampa's Billy Quarantillo, Saturday's match-up against Edson Barboza is truly the biggest battle of his mixed martial arts career. He's been fighting professionally for more than a decade, and he's finally worked his way up to the highest level in the sport. "It’s my whole entire life. I have my family life, but my working life has been a lot busier," Quarantillo said before a recent training session. "Doing this day in and day out. Treating it like a full-time job, and treating like the highest-level athlete I can." Quarantillo, 34, is coming off an impressive TKO victory over Alexander Hernandez in December.
