Tiger Woods began play at the MGM Resorts The Challenge: Japan Skins wearing a navy blue sweater vest over a light blue-and-white striped shirt. Jason Day, meanwhile, was just in his shirt sleeves.
By the sixth hole, Woods has taken off the vest in favor of a full-length sweater.
By the seventh hole, Day was wearing Tiger’s sweater vest.
And Day wore that sweater vest right into the winner's circle.
