Roger = 36 (Reduction); Tennis = 27 (Reverse Reduction)

This accomplishment comes 173-days after his 36th birthday.
173, the 40th prime; Tom Brady is 40

And for the record, his birth year, '81, is right for 'tennis'.

Ritual = 27 / 45 / 81 / 81

ALSO worth mentioning, the man who established IKEA, who spent much of his life in Switzerland, where Roger Federer is from, was announced dead on this same day.

That was Ingvar Kamprad.
