2019 - 8th Year that Federer/Nadal/Djokovic finish in the top 3 together.

2007 - F, N, D
2008 - N, F, D
2009 - F, N, D
2010 - N, F, D
2011 - D, N, F
2014 - D, F, N
2018 - D, N, F
2019 - N, D, F

Never been a year with F, D, N

For perspective: McEnroe/Connors/Lendl did it in 4 years over a span of 4 years. These guys have done it over a span of 12 years.

It is not yet mathematically certain that Federer will finish 2019 in the top three. It is very likely, but it is not mathematically certain. If Medvedev wins the title and Federer loses in the semi-final, then Medvedev will be #3 and Federer #4.
