BRISBANE, Australia (AP) — Bulgaria's Grigor Dimitrov and Canada's Milos Roanic ensured no slip ups in their final outing of 2018 by having straight-set victories in their respective first round matches at the Brisbane International on Monday.
A semifinalist here last year, Dimitrov fired down nine aces and saved six of seven break points to beat Japan's Yoshihito Nishioka 6-3, 6-4 and advance into a second-round match against John Millman of Australia. He beat Tennys Sandgren of the United States 7-6 (6), 6-7 (6), 6-0.
Milos Raonic made lighter work of his encounter against Aljaz Bedene, cruising to a 6-0, 6-3 win over the Slovenian.
In the women's draw, Australian wild card Kimberly Birrell toppled world No.10 Daria Kasatkina 5-7 6-4 7-6 (7-3) in their first-round match.
After trading a set each in the opening two sets, 20-year-old Birrell then fought back from 3-5 down in the deciding set to force a tiebreak, before clinching victory in just over three hours.
Birrell will play Ukraine's Lesia Tsurenko, who beat Romania's Mihaela Buzarnescu 6-0, 6-2, in the next round.
It was a good day for the local hopes with qualifier Destanee Aiaiva beating France's Kristina Mladenovic in straight sets, 6-3 7-6 (7-2) to set up a second round match with U.S. Open champion and No. 2-seeded Naomi Osaka.
Also, fifth seed Karolina Pliskova of the Czech Republic rallied from a set and a break down to beat Kazakhstan's Yulia Putintseva 4-6, 6-3, 6-4, Donna Vekic cruised to a 6-1, 6-2 victory over Magdalena Rybarikova and No.6-seeded Kiki Bertens beat Belgium's Elise Mertens 6-2, 6-7 (6), 6-4.
Former U.S. Open winner and local favorite Sam Stosur had 10 aces but lost 4-6, 6-2, 6-2 to qualifier Marie Bouzkova of the Czech Republic.
Tuesday's draw is highlighted by the first appearance of defending champion Nick Kygrios, who plays Ryan Harrison of the U.S., and Britain's Andy Murray marking his return after injury in a first-round clash with Australia's James Duckworth.
