SHENZHEN, China — World No. 1 Simona Halep fired a warning to her Australian Open rivals Saturday, beating Katerina Siniakova in three sets to win the Shenzhen Open. The Romanian saw off the reigning champion from the Czech Republic 6-1, 2-6, 6-0 in 72 rollercoaster minutes in southern China. The 26-year-old Halep is guaranteed top seeding for the Australian Open, the season’s first Grand Slam, which begins in Melbourne on Jan. 15. Svitolina wins Brisbane; Kyrgios beats Dimitrov Elina Svitolina secured her first WTA title in Australia with a straight-set victory in the Brisbane International final Saturday, while Nick Kyrgios moved a step closer to claiming his first ATP title on home soil with a semifinal win over defending champion Grigor Dimitrov. Third-seeded Svitolina beat Belarusian qualifier Aliaksandra Sasnovich 6-2, 6-1 in a lopsided night final to win her 10th title on the women’s elite tour. Kyrgios hit 19 aces in a 3-6, 6-1, 6-4 win over top-seeded Grigor Dimitrov, who was playing his first tournament since winning the season-ending ATP Finals and rising to a career-high No. 3 ranking. Third-seeded Kyrgios, who won all three of his ATP titles in 2016, will face American Ryan Harrison in Sunday’s championship match. Harrison reached his third tour-level final with a 4-6, 7-6 (5), 6-4 win over Alex De Minaur, the 18-year-old Australian wild-card entry. Wozniacki-Goerges final Top seed Caroline Wozniacki battled through two matches within the space of just over four hours to set up a final against second seed Julia Goerges at the Auckland Classic on Saturday. Heavy rain throughout the week in New Zealand’s largest city had caused havoc with the schedule, forcing organisers to play the quarterfinals and both semifinals Saturday and move the final to Sunday. The Dane struggled in her earlier quarter-final against the 19-year-old American wildcard Sofia Kenin before winning the rain-affected match 4-6, 6-2, 6-4 just before 4 p.m. (0300 GMT). She returned at about 5.50.p.m. and then comfortably accounted for American qualifier Sachia Vickery, who had earlier upset third seed Agnieskza Radwanksa, in the 6-4 6-4 win. Goerges beat Polona Hercog 6-4 6-4 in the quarterfinals before moving into the final with a 6-1 6-4 win over Taiwan’s Hsieh Su-wei. — Agencies
