Analysis: Novak Djokovic 40-3 against Americans at Grand Slams: Who were the three Americans to taste victory over the 24-time Grand Slam champion?

Novak Djokovic boasts an incredible record at Grand Slam tournaments. He has won the most out of any player with 24, along with the most Australian Open titles with 10. Going into his 18th event at Flushing Meadows, the Serbian is targeting title number five.

He has made a positive start to the tournament, dumping out Learner Tien in straight sets before coming back from a set deficit to knock out qualifier Zachery Svajda. He will face Cameron Norrie in the third round at the US Open.

Unfortunately for Djokovic, that player represents Great Britain. If it were an American, like his earlier two opponents, then statistically, he would have had a better chance of making it through. The 38-year-old has faced Americans 43 times in major matches, only losing in three of them - Paul Goldstein, Andy Roddick, and Sam Querrey.

Paul Goldstein

Possibly the least known out of the three players to beat Djokovic, Goldstein began his career back in 1998 after having a promising young career. He never broke out onto the main stage in tennis, reaching a peak ranking of 58 in singles and 40 in doubles. He made five ATP doubles finals, but lost every one. Four of them were with Jim Thomas, who is now a politician. The other one, he partnered with Robert Kendrick. Adding to that, he also made a semi-final with Thomas at Flushing Meadows in 2005, but were defeated by the eventual champions. A year later, he made the quarters, the same year he faced up against a future legend of the sport.

An 18-year-old Djokovic would play his second tournament in Melbourne, the place where he would taste so much success. He was looking to get his first win down under, but could not find away past the American, who won his first Australian Open match since 2001. It would also prove to be his last in Australia and penultimate for his career. Goldstein won the tie 6–2, 1–6, 6–3, 6–2.

Andy Roddick

Djokovic would go three years without facing defeat to another American in a Grand Slam event. When it eventually came to former world number one Andy Roddick, it would prove to be a shock with Djokovic having won the title the year before. This had matched Roddick's tally of Grand Slams, with him winning the US Open back in 2003, utilising his blistering serve. He remains the last US Grand Slam champion.

He had since made four finals, three at WImbledon and one in New York, bu succumbed to defeat in all of them, amusingly all of them to Roger Federer.
