Berankis wins 52-minute set in a tiebreaker

Both players started confidently, holding their opening two service games to bring the set to 2-2. A forehand winner from Berankis brought up the set's first break point chance at love-40. The 26-year-old fired a forehand which landed flat on the baseline which Mannarino couldn't handle as he netted the return to go down a break. However, Mannarino then found himself with a break point of his own but Berankis denied him and went on to hold for 4-2. The next two service games were held to love as the 28-year-old found himself serving to stay in the opening set at 5-3.

A forehand which ended up long from the Frenchman gave Berankis double set point. Two good serves including an ace saw Mannarino deny Berankis the first set as he held serve. At 30-love, Mannarino chased down a drop shot from Berankis, played the ball back in court to which the Lithuanian netted to give the Frenchman three chances to break to level. Despite saving one of them, Berankis ended up losing the game and the break as the set went to 5-5. Two more comfortable holds of serve saw the first set go to the tiebreaker. After having three more set points saved, Berankis eventually won the set 7-6(7).

A hold of serve from the Frenchman brought him level in the set at 2-2. The two players then held serve as the set moved to 3-3 on the Berankis serve. A double fault at 30-40 gifted Mannarino his second break of the match as he went ahead for the first time in the set at 4-3. An ace to hold serve gave Mannarino a 5-3 lead. The Frenchman then put Berankis under pressure as he looked to stay in the second set. Three set points came and went for the Frenchman but he managed to close out the set at the fourth attempt with a forehand winner to level at one set apiece, 6-3.
