Looks like Roger Federer withdrew from Madrid just in time...
He is now the proud father of two boys as well as the twin girls. Mirka had twins again. Doubles anyone?
Names: Leonidas "Leo",
Lennard "Lenny"

Odds of having 2 sets of identical twins? Something like 70,000 to 1.
Congratulations to the Federer family, and best wishes and health to all.
Edited: the twins are identical, not fraternal (one egg, not two)
Respectfully,
masterclass
That is so weird, not that they had two sets of twins, but that they had them back-to-back.
Congrats to the Federer family.
