- Mexican Open
Mixed fortunes for Dimitrov and Sharapova down in Acapulco

Defending champion Grigor Dimitrov suffered a shock defeat to Ryan Harrison in the second round of the Mexican Open in Acapulco.
The Bulgarian third seed had beaten Harrison in last year's US Open but the American had his revenge in Mexico, claiming his first ever win over a top-10 ranked opponent.
The pair traded sets but Harrison flourished in the decider to come through 7-5 4-6 6-0.
"It happens," Dimitrov told the ATP Tour website. "It's just the way it is. It's a bad loss for me, but best of luck to Ryan in the upcoming rounds."
There were no such dramas for top two seeds Kei Nishikori and David Ferrer, both of whom booked their places in the quarter-finals with straight sets victories.
Last year's US Open finalist Nishikori lost just four games against Yen-Hsun Lu, with the Japanese needing just under an hour in a 6-1 6-3 victory to set up a clash with fifth seeded Ukrainian Alexandr Dolgopolov, who defeated Andreas Haider-Maurer 6-2 6-3.
Second seed Ferrer was made to work a little harder before prevailing 7-6(3) 6-4 against Marinko Matosevic. The Spaniard set up an intriguing encounter with highly-rated Australian Bernard Tomic, who upset eighth seeded German Benjamin Becker 4-6 6-3 6-2.
Kevin Anderson and Ivo Karlovic, seeded fourth and sixth respectively, were taken to three sets before sealing their places in the last eight, while seventh seed Santiago Giraldo succumbed to a 6-3 6-4 defeat to Viktor Troicki.
In the women's event, world number 51 Monica Puig pulled off a huge shock by thrashing second seed Sara Errani 6-1 6-1.
Errani, the 2012 and 2013 champion, had lost in straight sets in her previous meeting to the Puerto Rican, 38 places below her in the rankings, but this scoreline will still come as a shock for the Italian.
Top seed Maria Sharapova had no problems in seeing off Colombian lucky loser Mariana Duque-Marino 6-1 6-2 to seal her place in the quarter-finals, where she will face Magdalena Rybarikova, who hammered Elena Bogdan 6-0 6-2 in 44 minutes.
Caroline Garcia and Timea Bacsinszky, the third and fifth seeds respectively, also came through, while there were also wins for Mirjana Lucic-Baroni, Johanna Larsson and Sesil Karatantcheva.
