Roger Federer and Novak Djokovic have won the most 'Big Titles', although Djokovic's strike rate is better.

Big Titles: Djokovic Draws Level With Federer's Haul

Djokovic improves his strike rate at top-level tournaments

World No. 1 Novak Djokovic has drawn level with Roger Federer for the most 'Big Titles' - Grand Slam championships, Barclays ATP World Tour Finals' or ATP World Tour Masters 1000 crowns.

The Serbian drew level with Federer on 47 'Big Titles' as a result of becoming the first player to capture 30 ATP World Tour Masters 1000 titles after a 6-3, 7-5 victory over Kei Nishikori in the Rogers Cup final.

Djokovic has by the far the best conversion rate of any player, past or present, winning one Big Title for every 3.13 events played at this level.

Federer, who will not play for the rest of the 2016 season, has 47 'Big Titles', including 17 Grand Slams, six Barclays ATP World Tour Finals (both records) and he is third all-time with 24 ATP World Tour Masters 1000 crowns. The Swiss has played 205 tournaments at this level, averaging one title for each 4.38 events played.

Rafael Nadal, who will be playing at the Rio Olympics, also boasts an exceptional strike rate, winning one Big Title for every 3.52 appearances. He is joint second all-time (with Pete Sampras) for most Grand Slam titles won with 14, and outright second all-time for most ATP World Tour Masters 1000 titles won with 28 crowns, just two behind Djokovic's record haul.

Andy Murray, who captured his third Grand Slam championship at Wimbledon last month, has won 15 'Big Titles', including 12 ATP World Tour Masters 1000s. Murray, who has competed in the same era as Djokovic, Federer and Nadal, wins one Big Title for every 9.2 tournaments played.

Since the ATP World Tour Masters 1000 series launched in 1990, Sampras has been the only player to rival the 'Big Titles' strike rates of Djokovic, Nadal and Federer. A winner of 14 Grand Slam titles and five Barclays ATP World Tour Finals, the six-time year-end World No. 1 averaged one Big Title per 4.9 tournaments played.

One other player whose strike rate is in single figures is Andre Agassi, who at one time was the record Masters 1000 title holder with 17 titles, including six Miami crowns. Agassi also won eight majors and one season finale. His 26 'Big Titles' from 164 tournaments played came at an average of one title per 6.3 events played.

Those historical averages put in perspective the utter dominance Djokovic has displayed in his past 24 outings at this level dating back to the 2014 BNP Paribas Masters in Paris. During that time the Serb has won one Big Title for every 1.33 events he's played, going 5 of 7 at Grand Slams, 11 of 15 at Masters 1000s and 2 for 2 at Barclays ATP World Tour Finals.
