In what is set to be her final tournament, 23-time major champion Serena Williams will face Montenegro's Danka Kovinic in the first round of the US Open. 

Earlier this month, Williams announced her impending retirement after the US Open. A champion in New York six times, Williams will face No.80 Kovinic for the first time.

The 27-year-old Montenegrin reached a career-high ranking of No.46 in 2016 and became the first woman from her country to win a Hologic WTA Tour title last year at Charleston. In January, Kovinic broke new ground for Montenegro at the Australian Open after defeating Emma Raducanu to become the first woman from her country to reach the third round of a Slam.

The winner of that opener will face either No.2 Anett Kontaveit or Romania's Jaqueline Cristian.
