Jannik Sinner saved five match points before advancing past Spain’s Pablo Carreno Busta 5-7, 7-5, 7-5 in the third round of the Miami Open on Sunday, while second seed Alexander Zverev enjoyed a much smoother path to the last 16.

Carreno Busta had Sinner on the ropes in the 10th game of the second set before the Italian recovered to hold serve and convert on a chance in the next game.

They traded breaks in the third before a marathon 10th game in which the Spaniard almost broke his opponent for the win four times.

World No. 11 Sinner survived and converted on a chance in the next game to seize the advantage. Serving for the match, he clinched the affair with a forehand winner.

Zverev made short work of American Mackenzie McDonald, winning 6-2, 6-2 in 73 minutes to set up a last 16 meeting with Australian Thanasi Kokkinakis, who came through a tight contest against Denis Kudla 7-6(5), 4-6, 7-6 (4).

American Coco Gauff kept alive her bid for a maiden WTA 1000 title, firing off five aces to overcome China’s Zhang Shuai 7-6(1), 7-5.

“I just kind of mentally was hanging in there. I wasn’t playing my best,” Gauff told reporters.

Spanish fifth seed Paula Badosa scored a 6-3 6-2 win over Kazakhstan’s Yulia Putintseva, who was so frustrated with her display she slammed her racquet into the ground with such force that it flew back up and almost hit her.

Badosa next faces Czech wildcard Linda Fruhvirtova, who advanced after former world No.1 Victoria Azarenka retired midway through the second set.

Bopanna show

India’s Rohan Bopanna and Canadian partner Denis Shapovalov stunned top-seeded Croatian pair of Nikola Mektic and Mate Pavic 6-3, 7-6(3) to enter the men’s doubles quarter finals. The duo will next face the sixth-seeded pair of Wesley Koolhof of Netherlands and Britain’s Neal

Skupski. Bopanna and Shapovalov had registered a 6-7(5) 6-2 10-3 win over Marceloa Avrevalo of El Salvador and Jean-Juien Rojer of Netherlands in the opening round.
