Andy Murray loses to brother Jamie in Montreal doubles encounter

Andy Murray breezed into the quarter-finals of the Montreal Masters but brother Jamie claimed the bragging rights after defeating his younger sibling in their doubles encounter.

The world No 3 needed just 65 minutes to beat Gilles Muller 6-3 6-2 in Montreal to set up a last-eight encounter with either Jo-Wilfried Tsonga or Bernard Tomic in the singles.

He was back on court just over an hour later, alongside Leander Paes against brother Jamie and his doubles partner John Peers - the first time the Murrays had competed against each other in a Tour-level match.

Seventh seeds Jamie and Peers, finalists at Wimbledon this year, edged the first set and looked to be cruising towards victory after leading 3-0 and 5-1 in the second-set tiebreak.

Andy, who has played alongside Jamie in Davis Cup doubles, and Paes hit back but were eventually beaten 6-4 7-6 (11-9).

After playing Andy competitively for the first time, Jamie told the ATP Tour's official website: "It was weird. We've only ever played together.

"It's weird to not get really pumped up when you play and every time you look down the other side of the net, that's your brother there.

"But I think we did well from a team point of view and I think me and Andy did a pretty good job of dealing with the situation, which was obviously not that natural. We're happy to win."

Earlier, Andy, playing for the third day in a row after defeating Tommy Robredo in a clash that was held over until Wednesday afternoon, recovered from a sluggish start to reach the last eight.
