(Reuters) - World number one Ash Barty will head to the U.S. Open in peak form after ending Swiss wildcard Jil Teichmann's brave run with a 6-3 6-1 defeat to claim the Western and Southern Open title in Cincinnati on Sunday.

Wimbledon champion Barty will now bid for her third Grand Slam crown and first on hardcourt at New York after humbling major winners Angelique Kerber, Victoria Azarenka and Barbora Krejcikova.
