Better with age? How Djokovic's post-30 Grand Slam numbers stack ...

In terms of post-30 major match wins, Federer managed 146, while Nadal has the fewest of this star quartet with 114.

The Spaniard lost 14 times at Grand Slams after his 30th birthday, which matches Djokovic’s tally. Federer, on the other hand, suffered 27 such defeats, and Williams slipped to 24 losses.

Djokovic won more Grand Slam matches than the other three superstars before turning 30, with 229 victories. Federer ranked second (223), ahead of Williams on 208 and Nadal on 200.

Diving into the individual tournaments, Djokovic’s most successful Grand Slam before he turned 30 was the US Open (62 match wins), with the AO next (58). Nadal won an extraordinary 72 matches at Roland Garros, while Federer claimed 59 wins at both Wimbledon and AO. Wimbledon, meanwhile, was where Williams recorded her most match wins prior to her 30th birthday (60).

Williams is, of course, Djokovic’s equivalent when it comes to success at AO. The American owns the record for the most women’s singles titles at the event, with seven. That haul also includes the last major trophy she won, when she beat her sister Venus in the 2017 final.
