Overton, a junior at Indiana University, overcame an early two-hole deficit after matching the 36-hole qualifying record for any U.S. Golf Association event at 10-under 132.
'I just tried to shake it all off,' Overton said. 'It's exciting to shoot 64 and 68. That's awesome, but there is really nothing to get nervous about. I just try to have fun and enjoy the experience. I'm just trying to soak it all in.'
Defending champion Ryan Moore of UNLV also won his opening match at Blue Heron Pines, rallying to beat Zack King 3 and 2.
'If I wasn't as experienced as I am, being three down through six holes, I could have started putting pressure on myself and started worrying,' Moore said. 'But, I said it was match play and it can turn around like that.'
The 36-hole final is Saturday in the tournament limited to amateurs who do not have playing privileges on a private course.
