Rafael Nadal has put his loss to Dominic Thiem in Madrid behind him by dropping just one game against Damir Dzumhur in his opening match of the Italian Open.
Defeat in the quarter-finals last week meant not just the end of his 50-set winning streak on clay but also his latest stay as world No.1, with Roger Federer reclaiming the spot.
But Nadal can take it back by winning in Rome and he set his stall out by blitzing Dzumhur 6-1 6-0 in an hour.
It is the 13th time in his career Nadal has dropped only one game in a match, but he is still looking for his first 'double bagel'.
"It was important, after a loss in Madrid, to come back strong," the 31-year-old, who received a bye in the opening round, said. "And that's what I did today.
"I went on court with the right intensity. I don't know how many mistakes I made, but not many. I also had control, more or less, of a high percentage of the points. That was the way that I want to play."
Nadal, gearing up for his bid for an 11th French Open title next month, would have been hoping for a revenge rematch against sixth seed Thiem after the Austrian ended his winning run last week.
However, after a two-hour battle, Italy's Fabio Fognini prevailed in a raucous atmosphere on the Centrale Court, the home favourite coming through 6-4 1-6 6-3.
Novak Djokovic reached the final last year and faces a big ranking drop if he does not come close to matching that.The Serbian has been untroubled thus far and defeated Nikoloz Basilashvili 6-4 6-2 to reach the third round.
Another shock saw Kei Nishikori, who continues to work his way back up the rankings after wrist problems, defeat third seed Grigor Dimitrov 6-7 (4/7) 7-5 6-4, while eighth seed John Isner lost in three tie-breaks to Albert Ramos-Vinolas.
