Andy Murray got his clay court season under way with a straightforward win over Edouard Roger-Vasselin to progress to the last 16 at the Monto Carlo Masters.
The British number one saw out the tie 6-1 6-4 to set up a clash with dangerous Swiss Stanislas Wawrinka.
oger-Vasselin, ranked 81 in the world, had come through qualifying before beating Robin Haase in the first round and perhaps would have hoped an upset was possible with it being Murray’s first match on clay this year.
The world number two was not fazed, however, and cruised into a 4-0 lead, though was broken once before claiming the first set without fuss.
Two time violations, one on a crucial break-back point, sparked some choice words from Murray towards the umpire, but it wasn’t enough to put him off his stride and see out the match comfortably.
After the match Murray explained his frustration at the umpire’s decision to pull him up a second time for pushing the 25 second limit between points – something umpires have been instructed to tighten up on this year.
"The only issue I have with it is, in the whole time over four months, I've yet to see the receiver given a time violation; it's always the server that's given it,” he said.
"The first one I agreed with, I said nothing about it, the second one he was checking his strings.”
Murray will likely be given a sterner test by Wawrinka but the form of another man is looking ominous for the rest of the field.
Rafael Nadal came through 6-1 6-2 winner against Marinko Matosevic to make it an incredible 43 matches unbeaten in this tournament.
The last time Nadal lost at Monte Carlo was ten years ago as a 16-year-old against Guillermo Coria.
World number one Novak Djokovic was not so comfortable coming through his clash with Mikhail Youzhny 4-6 6-1 6-4.
Djokovic only confirmed he would be playing at the tournament on Tuesday after doubts an ankle injury he suffered earlier this month threatened to rule him out.
It looked as though he had come back too soon when Youzhny went into a 5-1 lead in the first set, but the Serbian rallied well to eventually win it.
Djokovic will meet Juan Monaco in the next round and the Argentine came through in three in a controversial clash with Ernest Gulbis, where the Latvian was penalised a game for repeated smashing his racket.
Nadal's next victim is Philipp Kohlschreiber of Germany, while fourth seed Tomas Berdych came through 7-5 6-4 against Marcel Granollers.
