Andy Murray put his doubles disappointment behind him to move safely through to the third round of the singles with victory over Juan Monaco in Rio.The world No.2 was very upset after he and brother Jamie lost their doubles opener on Sunday night. The pair had set their sights firmly on a medal after their Davis Cup heroics together but were beaten by Brazilians Thomaz Bellucci and Andre Sa.Around the same time, Murrays chances of a second successive singles gold improved significantly when Novak Djokovic was beaten by Juan Martin Del Potro in the singles. Del Potros Argentinian teammate Monaco, ranked 107, appeared to hold few fears for Murray and so it proved as the world number two prevailed 6-3 6-1 after only 69 minutes.Murray won the first three games, was pegged back to 3-2, but quickly forged ahead again, coming out on top of most of the long rallies and clinching the set with his fourth ace. Monaco, who could well be an opponent for Murray in Septembers Davis Cup semifinal, had won two of his previous five matches against the Scot but both were more than five years ago.The many Argentinians in the crowd were providing loud support to Monaco but his serve was taking a pounding and Murray quickly moved into a 4-0 lead in the second set.The Scot, whose potential quarter-final opponent David Ferrer was knocked out by Evgeny Donskoy, kept his foot firmly on Monacos throat and a missed backhand from the Argentinian sealed his fate.Meanwhile, it was confirmed on Tuesday that Jamie Murray and Johanna Konta will be Britains entry in the mixed doubles. Andy also entered with Wimbledon champion Heather Watson but her ranking of 66 left them 18th in the entry list, which is decided on combined rankings, for the 16-team draw.Rafael Nadal, who is still in singles and doubles, will challenge for a third medal alongside French Open champion Garbine Muguruza while Venus Williams hopes of a fifth Olympic gold are still alive after she entered with Rajeev Ram.Djokovics Games are definitely over, though, and the world number one revealed after his doubles loss on Monday night that he will skip the Masters event in Cincinnati next week and will not play again until the US Open.Nike Vapormax Tukku .
