Aryna Sabalenka is the first woman to retain the US Open title since Serena Williams in 2014

World number one Aryna Sabalenka battled past home hope Amanda Anisimova to retain her US Open title and finally secure her first Grand Slam trophy of the year.

Sabalenka maintained a steadier level to win 6-3 7-6 (7-3) in a battle between two of the biggest ball-strikers in the women's game.

Victory did not come without some tension, however.

Defending champion Sabalenka was unable to serve out the match at 5-4, but recovered to dominate the tie-break and seal victory on her third match point.
