Simona Halep reach semis with dominating displays

Rafa Nadal produced an assured display to beat big-serving American John Isner 6-4 7-6(0) at the China Open on Friday and set up a semi-final clash with third seed Grigor Dimitrov.
The top-seeded Spaniard eased to his 59th victory of the year, breaking sixth seed DJ LeMahieu Authentic Jersey sner at 5-4 and holding his nerve to sweep a second-set tiebreak.
"I think I played a solid match," Nadal said. "I played very well, changing good directions...I think on return I did well.
"It's an important victory for me, of course, against a player that arrived here playing so well, winning two great matches. For me it's an important one and I'm very happy."
Dimitrov had to dig deep after being pushed hard in his quarter-final against Spain's Roberto Bautista Agut, but held out to beat the fifth seed 7-6(5) 4-6 6-2 in two hours and 29 minutes.
Dimitrov and Nadal have met on nine previous occasions - of which the Spaniard has won eight - but the Bulgarian's only victory http://www.authenticcoloradorockies.com/Dj-Lemahieu-Jersey over the world number one came in the Beijing quarter-finals last year.
"He is a player that I really like, a good friend on the tour," Nadal added. "I think Grigor is a player always with a great attitude, with a positive character. I'm happy for him that he's having a good year.
"Tomorrow will be a tough one, for sure. He's playing well."
Dimitrov's victory kept him in the hunt for a spot in next month's ATP Finals, and the 26-year-old stayed fifth in the Race to London rankings but has closed the gap on fourth-placed Austrian Dominic Thiem to 440 points.
Australian Nick Kyrgios sent down 12 aces against qualifier Steve Darcis, winning the first set 6-0 and going 3-0 up in the second before the Belgian retired due to injury.
Kyrgios, seeded eighth in China, will face second seed Alexander Zverev in the last four after the Christian Yelich Authentic Jersey after beating Russian Daria Kasatkina 6-2 6-1 on Friday.
Halep, who lost to Kasatkina in the second round of last month's Wuhan Open, was never at risk of suffering a second consecutive defeat by the 20-year-old, sending down 19 winners to wrap up the win in just over an hour.
"I think I played much better than Wuhan," the Romanian said after the match. "I changed tactics and worked pretty well. I just played my game and my style, and I was very consistent and solid as well."
The tournament in Beijing has already seen Halep register a first career victory over Russian Maria Sharapova, and the second http://www.authenticmiamimarlins.com/Dee-Gordon-Jersey seed now has an opportunity to level her head-to-head with Jelena Ostapenko, who beat her in this year's French Open final.
The mercurial Latvian bested Sorana Cirstea 6-4 6-4 in an error-strewn quarter-final that saw both players struggling to hold serve.
Ostapenko made a typically high 33 unforced errors, but her powerful forehand kept her out of trouble against Romanian Cirstea, who is also her doubles partner.
Twice-Wimbledon champion Petra Kvitova fought off fatigue to dominate Czech compatriot Barbora Strycova 6-3 6-4 and reach her third Beijing semi-final.
Kvitova, who produced 33 winners offset by 43 unforced errors, said she was tired but very happy with the victory, and will meet Caroline Garcia in the last four.
"I couldn't just imagine this coming to Asia," Kvitova said. "I'm already happy. I love these big matches anyway, so I will do my best tomorrow.
"I felt a little bit tired today maybe. On the court I felt pretty slow. Maybe I wasn't, but that was my feeling. Sometimes it's pretty confusing."
Garcia came through a gruelling contest that stretched for three hours and 21 minutes against world number three Elina Svitolina of Ukraine in the day's final match.
Playing with her right thigh heavily strapped, the Frenchwoman lost the first set, but clung on as the clock at the National Tennis Stadium ticked past midnight to prevail 6-7(5) 7-5 7-6(6).
