It wasn’t the most competitive or gruelling battle between the two sisters but the aura and romanticism surrounding the rivalry between the two kept the audience on the edge of their seats throughout.

However, once Serena got the break in the seventh game of the second set and held her serve to go 5-3 up, there were smiles on Alexis Ohanian’s face who knew the record was just a game away.
