ROGER FEDERER lives to fight another day after beating Matteo Berrettini in straight sets.
The Swiss ace faced an early exit from the competition after losing to Dominic Thiem on Sunday.
But he overcame the pressure to win 7-6 6-3 against the Italian world number eight, who will not be able to reach the semi-finals.
Later this evening, Federer’s conqueror Thiem looks to upset second seed Novak Djokovic.
The Serb is eyeing a sixth title in the competition, but fell at the final hurdle to Alexander Zverev 12 months ago.
