(CNN) -- Briton Andy Murray's poor run of form has continued after the 22-year-old crashed out in the opening round of the Monte Carlo Masters on Wednesday.
Murray, who now lost successive first round matches after reaching the final of the Australian Open in January, was beaten 6-2 6-1 by world number 33 Philipp Kohlschreiber in just over an hour of his maiden clay-court match of the season.
The third seed reached the semifinals here last year, but was sadly out of sorts as his 26-year-old German opponent wrapped up a victory he described "as one of the best in his career".
"It was almost a perfect match from beginning to end. I made not many mistakes and I had a lot of power in my game," he told Sky Sports.
Elsewhere, Rafael Nadal won his 28th consecutive match in Monte Carlo after crushing Dutchman Thiemo de Bakker 6-1 6-0.
The second-seeded Spaniard, who is bidding for a sixth straight Monaco title, has not suffered defeat in Monaco since losing in the third round to Argentine Guillermo Coria in 2003.
Top seed Novak Djokovic is also through to the third round following a 6-2 6-3 win over Florent Serra of France and the Serb will now face 13th-seeded Swiss Stanislas Wawrinka -- last weekend's Casablanca champion.
Spain's David Ferrer, seeded 11, defeated Andrey Golubev of Kazakhstan 6-3 6-2 while compatriot and 12th seed Tommy Robredo beat Serb Viktor Troicki 6-4 6-3.
