Rafael Nadal, number 1 in the world, insisted that he not focus on Wednesday to match Roger Federer's record with Glam Slam Haul at the Australian Open this month.
The 33-year-old won the French and US Open last year to move in one of his Swiss rival's 20 record highs.
Federer has been at the top of the list since 2009 when he overtook Pete Sampras' benchmark of 14 after winning a five-sentence thriller about Andy Roddick at Wimbledon.
A Nadal triumph in Melbourne could set the stage for a new landmark at Roland Garros, where he is a hot favorite for his 12 French Open titles.
But the Spaniard downplayed the potential historical impact after leading Spain to the ATP Cup quarter-finals.
"I honestly don't think much about Federer's file," said Nadal.
“My only goal is to continue playing good tennis, enjoying this sport and being happy. And if that happens and I stay healthy, the goal is to continue creating opportunities for the events that I'm going to play. "
Nadal's immediate focus is on leading the Spanish championship title at the first ATP Cup.
Spain have unbeaten qualifying for the round of 16 in Sydney after beating Nadal Japan in Group B in Perth.
However, the 19-time Grand Slam winner was replaced by the formally strong world number 72 Yoshihito Nishioka before he won 7: 6 (7: 4), 6: 4 in two hours and seven minutes.
Nadal made 36 casual mistakes and looked tired at times when he competed on the first day in Spain under the warm conditions of Perth.
"It was the first heat experience here in Australia, so we played in tough conditions and it was tough," he said. "I played against a player who set the season ablaze. It was an important win for me and the team."
