The fourth seeds saved all six break points they faced, including four deciding points, to boost their chances of reaching the semi-finals in London. Granollers and Zeballos move to 2-0 in Group Bob Bryan, having also defeated John Peers and Michael Venus in straight sets on Monday. The Rome champions will qualify for the last four at The O2 if Peers and Venus defeat Jurgen Melzer and Edouard Roger-Vasselin in the evening session.
Granollers and Zeballos have taken a 2-1 lead in their ATP Head2Head series against Pavic and Soares. The teams split their first two meetings earlier this year at the US Open (Pavic/Soares) and the Internazionali BNL d’Italia (Granollers/Zeballos).
Granollers and Zeballos were put under pressure in the first set, but they found big serves to save three break points and reach a tie-break. Zeballos found success on his return as he attacked Soares at the net and he fired an ace out wide to claim the first set.
The second set followed a similar pattern, with Granollers and Zeballos holding their nerves to save three more break points at the net. After saving match point on his serve at 5-6, deciding point, Soares extracted a volley error from Granollers and showed great reflexes at the net to clinch the second set.
Granollers and Zeballos outmanoeuvred their opponents at the net with a mix of power and precision to earn a 5/2 lead in the Match Tie-break. The Rome champions converted their fourth match point to end the two-hour, four-minute contest.
Pavic and Soares drop to 1-1 in Group Bob Bryan. The Croatian-Brazilian pair is also attempting to reach the semi-finals at The O2 on its tournament debut. Pavic and Soares will meet Peers and Venus in their final round robin match on Friday.
