For Lanting, the birdie pushed him back to 3-under for his round and gave him an opportunity to finish the championship outright. Cooper's birdie kept pace and ensured there would be little room for error on the demanding finishing hole.
The 18th ultimately provided one final twist.
Lanting closed with a birdie three, completing a 2-under-par 68, the low round among the championship's top finishers. Combined with his opening 72, Lanting posted an even-par total of 140.
Cooper needed to finish strongly to match him and did enough to keep his championship hopes alive. Despite a bogey at the 18th, Cooper signed for a second consecutive even-par 70, also finishing at 140.
With 36 holes unable to determine the inaugural champion, the two headed back out for a sudden-death playoff.
The opening extra hole did little to settle matters. Both Lanting and Cooper made bogey on hole 15, sending the championship to a second playoff hole.
This time, Lanting found the decisive score.
With the inaugural title on the line, Lanting made par on the second playoff hole, while Cooper was unable to match him. The par officially ended a two-day battle and gave Lanting the distinction of becoming the first-ever Colorado PGA Tour Championship winner. “I had my son three weeks ago, and thinking about how grateful I am for my wife, this is her first day solo with the two kids and big shoutout to her, she’s a rockstar,” Lanting said.
The victory capped an impressive comeback for Lanting, who began the final round two strokes behind Cooper before producing one of the strongest rounds of the day. His final-round 68 featured four birdies against just two bogeys, including three birdies during a bogey-free opening nine.
Cooper finished runner-up after showing remarkable resilience throughout the final round. His 70 included four birdies and four bogeys, and his back-to-back rounds of 70 made him the only player in the field to shoot even par in both rounds.
Behind the playoff participants, Matt Schalk, PGA General Manager of Colorado National Golf Club, made a final-round charge of his own. Schalk followed an opening 73 with a 1-under-par 69 to finish alone in third at 2-over 142, just two shots outside the playoff.
Defending Colorado PGA Professional Champion Geoff Keffer, Assistant PGA Professional at Lakewood Country Club, also moved up the leaderboard Tuesday. Keffer improved five shots from his opening-round 74 with a 1-under 69, finishing fourth at 3-over 143.
Tristin Goodwin, Teaching Professional at Experience Golf, rounded out the top five at 7-over 147 following rounds of 73 and 74.
Doug Rohrbaugh, PGA Head Professional at Aspen Golf Club, and Dan Sniffin, Director of Instruction at PGA of Omni Interlocken Resort and Golf Club, shared sixth at 9-over 149. Chris Kennedy of Murphy Creek Golf Course finished eighth at 10-over 150, while Tony Aranda, PGA Head Professional at Blackstone Country Club, made one of the largest moves of the final round, firing an even-par 70 after an opening 81 to climb into a tie for ninth with Brian Belz of Lenny's Ski & Golf, at 11-over 151.
But in the end, the inaugural season-ending championship belonged to Lanting.
The season-ending championship also marked the end of the 2026 Colorado PGA Player of the Year(POY) races. Congratulations to the following winners, who will be recognized at the Colorado PGA Fall Meeting on Monday, October 26th at The Club at Inverness, and the Colorado PGA Special Awards Gala on Friday, November 13th at Cherry Hills Country Club.
