MELBOURNE, Australia (AP) — The Latest on Tuesday at the Australian Open (all times local):
Former U.S. Open finalist Madison Keys beat Australian wild-card entry Destanee Aiava 6-2, 6-2 to open play at Rod Laver Arena on Day 2 of the Australian Open.
Keys broke Aiava's serve in the third game of the second set to go up 2-1, then again in the seventh game thanks in part to an Aiava double-fault and two forehand errors.
Keys' best result at Melbourne Park was in 2015 when she beat Venus Williams and Petra Kvitova en route to the semifinals, where she lost to Serena Williams. She also made the quarterfinals last year, losing to 2016 champion Angelique Kerber.
The now 18-year-old Aiava had the distinction of being the first male or female player born in this century to play in a main draw Grand Slam singles match when she received a wild card in 2017. She lost in the first round.
Another early winner Tuesday was seventh-seeded Karolina Pliskova, who beat Czech qualifier Karolina Muchova 6-3, 6-2.
Novak Djokovic and Serena Williams, with 13 Australian Open titles between them, play their first-round matches Tuesday at what is expected to be a steamy Melbourne Park.
Williams, who has seven Australian titles and last won here in 2017, plays Tatjana Maria in the second match at Rod Laver Arena.
Top-seeded Djokovic, who will attempt to win a men's record seventh Australian title, opens night play on the same court against American Mitchell Krueger.
The temperature was already 30 degrees Celsius (86 Fahrenheit) when play began on all courts shortly after 11 a.m. local time and it was expected to rise by several degrees.
The sun and humidity added to the sultry conditions, forcing many of the early spectators to take relief by standing under giant cooling mist machines.
