PARIS Logan Cooke Rush Jersey , June 5 (Xinhua) -- Men's world No. 1 Andy Murray secured his place in the last eight at the French Open with a sweep over Karen Khachanov on Monday, setting up a quarter-final clash with Asian top-ranked Kei Nishikori.
Murray beat the 21-year-old Khachanov 6-3, 6-4, 6-4 in two hours and four minutes to record the 650th win of his career.
Murray finished five aces and a total of 29 winners. Last year's finalist could bounce back immediately after suffering two breaks in the third set.
"I think today was probably the best I have played overall," said the top seed.
For Khachanov, playing on the center court at Roland Garros was a pleasure Ronnie Harrison Rush Jersey , but losing the match was always hard to bite.
"It's never fun to lose a match, but I took a great experience from this match to play on the center court," he said.
After experiencing a five-set thriller in the third round dalayed by the rain, the eighth-seeded Nishikori regrouped himself and came back from one set down to see off Fernando Verdasco 0-6, 6-4, 6-4 Telvin Smith Rush Jersey , 6-0.
The Japanese won 73 percent of net points, and he managed to overcome 46 unforced errors to cruise into the quarter-finals.

The first NASA explorer of its kind took off on a seven-year quest Thursday, chasing after a big, black, unexplored asteroid to gather a few handfuls of gravel for return to Earth.
These bite-size bits of ancient space rock from asteroid Bennu could hold clues to the origin of life, not just on our planet but potentially elsewhere in the solar system.
Thousands gathered to witness the evening launch of Osiris-Rex Blake Bortles Rush Jersey , a robotic hunter that looks something like a bird with its solar wings. The spacecraft took flight atop an Atlas V rocket, which soared a little before sunset on the mission, a U.S. first.
Victory was declared an hour later; launch controllers shook hands and embraced as the spacecraft shot out of Earth's orbit, bound for Bennu.
"Tonight is a night for celebration. We are on our way to an asteroid," said NASA's chief scientist, Ellen Stofan. After all A.J. Bouye Rush Jersey , "we've just done something amazing."
"We got everything just exactly perfect," added Osiris-Rex chief scientist Dante Lauretta of the University of Arizona. "It was an amazing evening for me and for this team."
It will take two years for Osiris-Rex to reach Bennu (BEHN'-oo), which is circling the sun in a slightly wider orbit than Earth's. The boxy spacecraft will actually go into orbit around the asteroid, seeking out the best spot before going in for a quick bite.
Round trip, the SUV-sized spacecraft will travel more than 4 billion miles (6 ? billion kilometers) by mission's end in 2023.
NASA has gone after comet dust and solar wind particles before, but never anything from an asteroid. It promises to be the biggest cosmic haul since the Apollo moon rocks.
The roundish rock — an estimated 1 Myles Jack Rush Jersey ,600-plus feet (500 meters) across and taller than the Empire State Building — is believed to harbor carbon dating back 4.5 billion years, to the beginning of our solar system. That makes it a time capsule and a scientific prize.
"We will make discoveries on this mission that we have not anticipated. It's exciting!" said Bill Nye, "The Science Guy," chief executive officer of the Planetary Society.
The launch came 50 years to the day that the first "Star Trek" episode aired on TV. NASA launch commentator Mike Curie referenced the anniversary, urging the spacecraft at liftoff "to boldly go" to Bennu and back. This is yet another example of NASA "turning science fiction into science fact," Stofan noted.
Osiris-Rex may lead to asteroid-mining missions Leonard Fournette Rush Jersey , according to scientists, and could help protect the planet from menacing space rocks.
Japan already has visited an asteroid and returned some specks (the mission didn't go quite as planned), and is chasing another space rock for even more samples. Osiris-Rex's bounty, however, should surpass that; Lauretta and his team want at least 60 grams of dust and gravel, or 2 ounces' worth when the big day comes in 2020. Ground tests have yielded eight times that in a single scoop Jalen Ramsey Rush Jersey , so hopes are high for four to five handfuls.
Osiris-Rex will hover like a hummingbird over Bennu, according to Lauretta, as the spacecraft's 10-foot (3-meter) mechanical arm touches down like a pogo stick on the surface for three to five seconds. Thrusters will shoot out nitrogen gas to stir up the surface, and the loose particles will be sucked up into the device. Spacecraft managers call it "the gentle high five." They get just three shots at this, before the nitrogen gas runs out and the effort abandoned.
The team opted for this touch-and-go procedure instead of landing to increase the odds of success. Despite extensive observations of Bennu from ground and space telescopes, no one knows exactly what to expect there A. J. Cann Jersey , and it could be difficult if not impossible to anchor a spacecraft on the surface, Lauretta said.
Osiris-Rex's freed sample container — the same kind used for the comet-dust retrieval — will parachute down with the pristine asteroid treasure in Utah. The mother spacecraft, meanwhile, will continue its orbit of the sun.
Among the 8,000 NASA launch guests was the schoolboy who came up with the asteroid's name for a contest.
