Andy Murray suffered a humiliating 6-3 6-1 defeat to hot prospect Kevin Anderson in the second round of the Rogers Cup in Montreal.
The world number four never looked happy as the big-serving South African handed him a shellacking in just 69 minutes.
Anderson dominated from the outset, winning 93 percent of first serves in taking the first set, breaking to lead 4-2 and successfully serving it out.
Murray's serve then failed him in the next as his opponent picked off his second serve almost at will, while the Scot coughed up five double faults in the match.
Anderson set the tone early on with an ace as he took the first game to love, breaking Murray in the next with the Briton double faulting twice.
The world number 35 was relentless, again holding to love for 3-0, before Murray finally got on the board in the fourth game.
Both men held serve and Anderson had a great chance to take a 5-2 lead but put a drop shot into the net with his opponent stranded.
However, he prevailed as a fierce shot pressured Murray to net a return forcing the world number four to serve to stay in the set.
Murray started well with a controlled drop shot giving Anderson no chance but the Dunblane-born player was forced to dig deep by a confident opponent before holding.
It was, though, merely delaying the inevitable, Anderson ending the set the way he started it, serving out with an ace.
Murray then began the second set with a double fault as Anderson was relentless, forcing his way to double break point and going 1-0 up.
Both men held before the Scot finally forced his way to double break point in the fourth game but a difficult bounce saw him put the ball wide.
He was thwarted again when he was unable to return a ferocious drive from Anderson who eventually prevailed as he continued to control the game as Murray netted a return.
The match was going away from Murray and the fifth game saw him produce his fourth double fault of the day before he miscued a simple shot, the ball going wide to give Anderson double break point and he was gifted a second break when the Scot netted.
Murray was being pushed around the court and although he produced the odd spark, more often than not it was Anderson who emerged victorious from any kind of rally.
A netted forehand saw Anderson go 5-1 up and Murray serving to stay in the match but he double faulted for the fifth time and then had no answer to a ferocious return as Anderson progressed.
Anderson told Sky Sports 4: "Andy is a great player and has had an incredible career.
"I knew it was going to be tough.
"The last time I played Andy was in Australia and I didn't come forward very well.
"I knew I had to come in.
"I played some good points and I won the majority of those."
