At the Western and Southern Open Andy Murray prevailed in a rain-delayed match Thursday, 18 August, beating Kevin Anderson 6-3, 6-2 to win his 20th match in a row, a career high.

Andy Murray, now a double Olympic champion, had hoped for some rain in Cincinnati, giving him time to rest following his exploits in Brazil. Indeed, the rain came only two points into his match against Kevin Anderson on Thursday night - a downpour forced an hour-long delay.

Despite the stoppage, Murray was steady throughout, committing only 11 unforced errors. The Scot will look to extend his career-high twenty match winning-streak against Bernard Tomic in the quaret-finals.

World No. 7 Kei Nishikori fell in straight sets to Australia's Tomic, missing out on the the last eight in his first tournament after winning a bronze medal in Rio.

After dominating Fernando Verdasco in his last match, Croatia's Marin Cilic battled sixth-seeded Tomas Berdych of the Czech Republic through three sets and prevailed 6-3, 4-6, 6-4. Next up for Cilic is a meeting with compatriot Borna Coric.

Japanese qualifier Yuichi Sugita fell in the round of 16, taking world No. 6 Milos Raonic to three sets in a 6-1, 3-6, 6-1 defeat. Raonic will face the winner of Gael Monfils and Dominic Thiem.

Steve Johnson also advanced to the quarter-finals on Thursday and put himself in position to become the top American in the ATP rankings heading into the U.S. Open.

Johnson beat Jo-Wilfried Tsonga 6-3, 7-6 meaning that he'll move into the American top spot next week, knocking John Isner out of the slot that he's held every week since 29th July, 2013.
