Paris - British fourth seed Andy Murray reached the French Open second round on Tuesday with a 6-1, 7-5, 6-0 win over Japan's world No 68 Tatsuma Ito.
Murray will tackle Finland's Jarkko Nieminen for a place in the last 32.
Murray, showing no sign of the back injury which he aggravated at the Rome Masters, coasted through the first set against the Roland Garros debutant in just 25 minutes.
The Japanese player did have three break points in the eighth game of the second set, but once Murray had dealt with that danger, there was no way back for 24-year-old Ito.
Murray, a semi-finalist at Roland Garros last year, broke twice in the third set for a 3-0 lead and again for 5-0 before comfortably wrapping up proceedings after just 95 minutes on court.
In taking the third set, Murray allowed his opponent just six points.
