Fritsch, from Ottawa, made three early birdies and was never seriously challenged the rest of the way. He finished the six-round tournament at 27-under 402.
"I didn't come here to shoot 27-under. I'm surprised," said Fritsch. "I couldn't imagine coming here and doing that."
Fritsch earned US$25,000 with the victory.
Andrew Landry finished second. He was among the next nine players who are fully exempt for the first dozen events in 2015. The group that finished between 11th and 45th place (including ties) are exempt for up to nine events.
