Calkins, of Manhattan Beach, Calif., led Exber, of Las Vegas, by two at the turn. Exber’s birdie on 15 and Calkins’ three-putt bogey on the treacherous 17th green allowed Exber to draw even.
While the focus had been on Exber and Calkins, another man in the final group was also making a move. David Oas, of Oceanside, Calif., stood in the middle of the fairway at the par-5 17th and crushed a driver to within 10 feet of the green. He got up and down for the only birdie in the group, which allowed Oas to get within one of the lead going to the 18th tee.
After both Exber and Calkins parred the closing hole, it was back to the 18th tee. After two more trips down that hole and still no winner, the playoff moved to the 10th, an uphill par 4 with a large, steeply sloped green.
Both players found the center of the fairway and hit good approach shots into the green. Exber putted first but left it short, and after carefully watching Exber’s putt, Calkins lagged to within a foot before tapping in for his par. When Exber missed his putt, it left Calkins with the victory.
Calkins was runner-up at the Hesler in 2018 and tied for second at the Ralph Bogart Tournament. His head-to-head defeat of Exber is significant, considering that the defending champion is a two-time Stocker Cup champion, an SNGA stalwart and the reigning Canadian Senior Amateur champion.
