Germany’s Angelique Kerber backed up her status as the new world number one with a thrilling win over Czech Karolina Pliskova in the US Open final.
Kerber, 28, won 6-3 4-6 6-4 in New York to add the US Open to her victory at the Australian Open in January.
Pliskova’s semi-final win over Serena Williams had already ensured the German will top the new rankings on Monday.
“All my dreams came true today and I’m just trying to enjoy the moment,” said Kerber.
“It’s incredible. I’m standing here with a second Grand Slam trophy and it means so much to me.”
Kerber was appearing in her third Grand Slam final of 2016.
