TENNIS

Novak Djokovic needed medical attention after accidentally getting knocked on the head by a water bottle after a win at the Italian Open. A man was leaning over a railing to hand Djokovic a notebook for a signature and an aluminum-type water bottle fell out of his backpack and hit the player on the top of his head. Djokovic had a bump on his head and was checked by doctors.

LPGA GOLF

Rose Zhang was threatening to run away with the Cognizant Founders Cup and end Nelly Korda’s bid for a record sixth straight win on the LPGA Tour.
