Isner upsets Djokovic in Cincinnati

MANILA, Philippines – American John Isner shocked world number one Novak Djokovic to reach the semi-finals of the Western and Southern Open, ending the Serb’s bid to complete the career Golden Masters slam. In a heavyweight match-up featuring two of the game’s big-hitters, it was Isner who came out on top after a slugfest lasting two hours and 23 minutes to set up a meeting in the last four with Argentine Juan Martin del Potro. Djokovic, a four-time runner-up on the Cincinnati hardcourts, had been eager to take the final step this year and become the first player to complete the career Golden Masters by winning all nine World Tour Masters titles. -- ANC, August 18, 2013
