Eaks claimed a check for $240,000 for his first victory among golf seniors, and has earned over $1 million this season.
"My caddie really set the tone for me on the back nine," Eaks said. "I might have played a little too safe at times, but it worked out. You just learn every day out here. I'm just so thankful that I get to play this tour."
The 55-year-old Eaks, who has three second-place finishes this year, dropped in back-to-back birdie putts at No. 8 and 9, and held off his nearest competition.
