Andy Murray breezed into the quarter-finals of the Rogers Cup but brother Jamie claimed the bragging rights after defeating his younger sibling in their doubles encounter.
The world number three 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).
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 against Muller.
The 2009 and 2010 champion found himself 0-40 down on serve in the opening game although the Scot battled back to hold as Muller wasted four break points.
The British number one, who will move up to second in the world rankings if he reaches the final here, took the initiative in the fourth game, breaking with a delightful lob.
Muller could not find a way back into the game as a rampant Murray made light of windy conditions to wrap up the first set inside 31 minutes.
It did not get any better for the Luxembourg left-hander as he dropped his serve without winning a point at the start of the second set and then again in the fifth game to gift Murray a 4-1 lead.
A mid-set lapse from Murray allowed Muller a route back in as he broke straight back, but three double faults from the world number 46 restored the two-break cushion for Murray, who then held to book his quarter-final place.
