In the third, Muguruza looked to be firmly in control as an increasingly tired looking Gavrilova misfired to give her opponent a daunting double break, 4-0 lead. But Gavrilova never gave up, holding serve at 4-1 to stop the rot and take the wind out of Muguruza’s sails. She went on to reel off four games in a row to get ahead 5-4, earning her first lead of the set.
A pair of back to back breaks – with Gavrilova breaking Muguruza from match point down – sent the match into a third set tiebreaker. They were toe to toe throughout the decider, which saw Gavrilova save a second match point, before finally edging ahead and winning the last three points in a row to close out the marathon match. At three hours and nine minutes, it clocks in at the fourth longest WTA match of the year so far.
