Andy Murray is safely through to the third round of the men's singles draw at Rio 2016 after an emphatic straight sets victory over Juan Monaco. The world number two, who cruised past Viktor Troicki of Serbia earlier this week, was rarely troubled by his Argentine opponent and comfortably progressed 6-3, 6-1 in little over an hour on centre court at the Olympic Tennis Centre in Barra da Tijuca.

Looking to show off his obvious dominance, Murray won each of the opening three games before Monaco hit back to reduce the deficit to one. However, the London 2012 gold medallist quickly broke again to dismiss any notion of a fightback and later spurned two set points before hammering home his considerable advantage with an ace.

He broke serve again twice in quick succession during the early stages of the second set and never looked back, giving up just one more game. Serving to stay in the match, Monaco, victorious over Mirza Basic of Bosnia and Herzegovina in round one, was unable to hold him off and a predictably heavy defeat was confirmed when he sent a forehand crashing into the net.

Next up for three-time grand slam winner Murray in the defence of his Olympic title is a meeting with either France's Benoit Paire or Fabio Fognini of Italy, who play each other this evening. The 29-year-old and older brother Jamie are out of the men's doubles competition after losing to Brazilian pair Thomaz Bellucci and Andre Sa following a long second-set tiebreak.

Jamie Murray and Johanna Konta have now been confirmed by the British Olympic Association (BOA) as Team GB's mixed doubles pairing. Andy and Heather Watson, placed second on the list of alternates, will not compete unless there are two withdrawals before the competition gets underway. Their combined ranking is too high for automatic entry.
