Andy Murray crashed out of the Monte Carlo Masters after being swept aside in a dismal performance against Stanilas Wawrinka.
The British number one made 24 unforced errors in a match he was never really in and his Swiss opponent ran out 6-1 6-2 winner to make the last eight.
Murray had hoped to further close the gap between he and world number one Novak Djokovic in Monte Carlo but he will now drop back to number three in the world as a result of this defeat.
The Scot has an indifferent record at this event, having only got as far as the last eight twice, and he lamented the number of unforced errors he made on the way to defeat.
“Twenty-four unforced errors is far too many - a set's worth," Murray told reporters.
“That's where half the points went. I started making a lot of errors - he was able to dictate all of the points from there.”
It means another slow start to the clay court season for Murray and he will have to do better when he plays next – at the Madrid Open on May 5.
He travels to Rome after Madrid in his last scheduled tournament before Roland Garros.
Defeat to Wawrinka will dent Murray’s confidence but he does not think it will affect him too greatly as he tries to improve on his weakest surface.
“I've had tough losses on the clay before and I've come back well from them. Hopefully today will be the same,'' he added
