– Angelique Kerber’s bad day: Nothing was working for the Australian Open champion in her disappointing 7-5, 6-1 loss to Zheng Saisai. It was Kerber’s first tour match since her Melbourne triumph and she struggled to find any rhythm off the ground, firing 38 unforced errors to Zheng’s eight. A frustrated Kerber told her coach Torben Beltz during their on-court coaching timeout that she felt “empty” inside.
“I was practicing very well in the last few days,” Kerber said. “But today, my practice this morning was not the best. So I was feeling not good from the beginning.
“I think you have sometimes days like this. Of course it’s sad that’s the first round here in Doha for me. Still, I mean, it was not my day. That’s all I can say today.”
The loss opens the door for No.3 Agnieszka Radwanska, who won in straight sets, to grab the No.2 ranking this week. She can do so if she wins the Doha title. After a day of upsets, Radwanska is now the highest ranked player in the draw.
– Zheng Saisai’s near-miss: After beating Australian Open champion Kerber, Zheng was back on court and nearly pulled off an even bigger upset over Australian Open champions Martina Hingis and Sania Mirza. Zheng and her partner Xu Yi-Fan led 4-2 in the match tiebreak before losing eight straight points to lose 6-4, 4-6, 10-4. The win extends Mirza and Hingis’ win streak to 41 consecutive matches.
– Simona Halep: The No.4 will lose ground in the rankings on Monday after wasting 7-5, 4-1 lead to lose 6-7(1), 6-4, 6-1 to Elena Vesnina. The win was Vesnina’s first Top 10 win since 2013.
With the loss, Halep went winless in the Middle East, a particularly frustrating result after she appeared to play much better during the Fed Cup weekend.
Halep has nearly 1,400 points to defend in Indian Wells and Miami.
– Garbiñe Muguruza set to return to the Top 4: The Spaniard rolled past Nao Hibino with a 6-2, 6-0 win in the first round in Doha and will move ahead of Halep in the rankings on Monday, at No.4, though she does have a chance to move up to No.3 this week as well.
– Daria Kasatkina continues to show promise: The 18-year-old held three match points against Roberta Vinci but couldn’t close, losing 2-6, 6-4, 7-6(3). Kasatkina keeps putting herself in winning positions in these key matches, but the nerves seem to be her undoing when trying to close things out. Experience should change that.
– Timea Babos, ace leader: Seven weeks into the season and the tour’s ace leaderboard may surprise you:
Babos knocked out Dubai Duty Free Tennis Championships winner Sara Errani to advance to the third round on Tuesday.
– Petra Kvitova gets on the board: Kvitova extended her streak to 18 consecutive wins over Czech opposition, beating Barbora Strycova 7-6(2), 6-4 for her second win of the season. She’ll play Jelena Ostapenko for a spot in the quarterfinals.
– Eugenie Bouchard’s draw opens up: The Canadian secured her ninth win of the year with a 7-6 (0), 7-5 win over Denisa Allertova in Doha. She’ll play Zheng for a spot in her first Premier quarterfinal since the 2014 Dongfeng Motor Wuhan Open.
– Lucie Safarova’s title defense ends early: Getting back on court after a long bout with a bacterial infection was a victory in itself for Safarova. But she has some way to go to rediscover her 2015 form, losing 7-6(6), 7-5 to No.162 Cagla Buyakakcay.
– Victoria Azarenka rebounds in Acapulco: The top seed was made to work but started her Mexico campaign with a 4-6, 6-3, 6-1 win over Polona Hercog. She plays Dominika Cibulkova in the second round. Cibulkova dropped a double-bagel win on Lourdes Dominguez Lino to start her tournament.
