At just 19 years old, flyweight Sergio Pettis (8-0) may soon be ready for the bigtime. “The Phenom” needed just 51 seconds to rack up a win over fellow striker Dillard Pegg (5-2). The bout served as the main event of Friday night’s Resurrection Fighting Alliance 8 event, which took place at The Rave/Eagles Club in Milwaukee, Wisc. The night’s main card aired on AXS TV. Pegg stepped in on late notice to replace longtime veteran Jeff Curran , who withdrew from the fight to look after his family, especially two young children, after their family dog was involved in an accident that threatened the animal’s life
