Rafael Nadal was not happy with his serve despite easing his way into the second round of the French Open with a straight-sets victory over Benoit Paire.
The Spaniard, who is chasing an unprecedented 10th title at Roland Garros, made light work of his French opponent, securing a comfortable 6-1 6-4 6-1 success in one hour and 54 minutes.
Next up for Nadal is a second-round clash with experienced Dutch player Robin Haase and the 30-year-old admits he must improve his serve to go far in this year’s tournament.
“I feel that some moments I was not serving well,” Nadal said. “I need to be very focused on the serve in my next match because returning can be tough and I need to play very solid.
“For me, it’s important to serve a little bit better. The rest of the things I am happy with.”
Nadal has enjoyed a return to form during 2017, winning three titles on the ATP Tour, including the Madrid Open earlier this month.
He also reached the final of the Australian Open in January, losing to old rival Roger Federer in five sets.
The 14-time major winner boasts an impressive record against Haase, winning both of their previous meetings including a five-set triumph at Wimbledon seven years ago.
Nadal is priced at 1.01 to secure another success over Haase in Paris on Wednesday while the Dutchman is available at 11.00 to spring a surprise.
