But the 34-year-old has slipped outside the top-200 in recent years and Federer has never in his career lost to a player of that ranking in a Grand Slam.
Still, there are more question marks on Federer’s fitness in this tournament than ever before and the Swiss tennis superstar has already ruled himself out of challenging for the title.
Instead, Federer admits that he’s hoping the chance to compete at Roland Garros will be the perfect way to warm up for Wimbledon this summer.
And he arguably looked in the best shape he has ever since making his long-awaited return from injury.
Istomin never truly challenged Federer with the 39-year-old dominating the match throughout with his effortless dropshots catching out his opponent on several occasions.
There were some occasions where Federer did appear to walk gingerly, but his confidence was none more so evident than his tweener attempt with the match all-but wrapped up in the third set.
Federer rarely had to get out of first gear to get past Istomin and that may be a cause of frustration further down the line.
Federer knows heading into the grasscourt season that he will need to go up against tougher opposition if he’s to add to his Grand Slam tally.
But for now, he will undoubtedly be pleased with his return to the claycourts at Roland Garros.
