Andreas Hartø is a Danish golfer with three wins (one, his first, as an amateur) on the European Challenge Tour, which is a lower-tier golf tour run by the PGA Europe Tour.
Anyway, he is technically a professional golfer and he is definitely pants-less—during final round action at the European Tour's Trophée Hassan II tournament in Morocco—while hitting a chip shot from the water, so that headline is 100 percent accurate. Stick around and watch the entire video as he shuffles, still sans pants, to mark his ball. Hartø finished at four under for the tournament.
