Rafael Nadal matched Roger Federer and Novak Djokovic by securing a fifth year-end number one, while also breaking a record set by the Serbian.

Federer was too good for Djokovic 6-4, 6-3 at the ATP Finals on Thursday, reaching the semifinals at the expense of the 16-time grand slam champion.

The result confirmed Nadal will finish the year at the top of the rankings for the fifth time.

The Spanish star joined Federer, Djokovic and Jimmy Connors on that tally, trailing only Pete Sampras (six).

It also marked the 16th straight year in which one of the 'Big Four' – Federer (2004-07 and 2009), Nadal (2008, 2010, 2013, 2017 and 2019), Djokovic (2011-12, 2014-15 and 2018) and Andy Murray (2016) – has finished as world number one.

At 33, Nadal is the oldest year-end number one in ATP rankings history. Djokovic, 31 last year, held that mark previously.

Federer (20) still leads his rivals for most grand slams, although Nadal (19) and Djokovic (16) closed the gap this year.
