American Gumberg triumphs in Hainan for second DP World Tour win
Gumberg, 30, finished the four rounds at Mission Hills on Hainan Island at 19 under par for his second DP World Tour title, following victory via playoff at the SDC Championship in South Africa in 2024.
At 15 under par in a three-way tie for third were Chinese 17-year-old Zhou Yanhan, England's Marcus Armitage and Spanish-born Adrian Otaegui, who now plays under the flag of the United Arab Emirates.
Gumberg started the final round with a birdie, but gave it back at the third before snagging further birdies at the sixth and 11th.
