The event was played at the Robert Trent Jones’ Grand National course.
The rising senior at Oxford took control of the match with a 30-foot birdie putt on No. 1 and closed it out with a 30-footer for birdie on No. 16.
“This means a lot,” Sanders said. “I’ve been putting in the hours in practice, and it feels good to finally pay off.”
Sanders went 2-up with a birdie on No. 4 and was 3-up through 12. Peters won the 14th hole, then Sanders closed it by winning the next two.
He won just as decisively in the quarter- and semifinals on Thursday.
“I played really well in all my matches. I played really solid,” Sanders said. “I just never let a negative thought creep into my head.”
Sanders will play in the Future Masters in Dothan July 1-3.
