Djokovic, wife Jelena welcome 2nd child

This year's US Open may be missing two of tennis' greatest champions, but it's seen two of their offspring come into the world.

On Saturday, just a day after Serena Williams and fiance Alexis Ohanian welcomed their first child, Novak Djokovic and his wife Jelena welcomed their second, according to Novak's former coach Boris Becker.

They've named the baby girl Tara. It's the couple's first daughter. Their son, Stefan, was born in October of 2014.

Djokovic is sitting out the remainder of the season, ostensibly to rehab an elbow injury, and hasn't played since Wimbledon. But this would appear to be a silver lining of - if not part of his reason for - taking some time away from the tour.
