Roger Federer won 61 titles from 85 finals in the 2000s decade, a tally which included 15 Grand Slam titles among a plethora of other records. Federer's 15th Slam of the decade arrived at 2009 Wimbledon, where he beat an inspired Andy Roddick in five sets, sealing the title with his first break of the Roddick serve all match.

In an eerie similarity, Djokovic in the 2010s also won 61 titles but from one fewer final, and like Federer in the 2000s, won 15 Grand Slams. Djokovic's 15th Grand Slam title of the 2010s also arrived at Wimbledon (2019), where the Serb recovered from 7-8 15-40 championship points down on Federer's serve to become the first winner at the grasscourt Major in 71 years to have saved multiple championship points.
