A FIVE-SET come-from-behind win to Sam Querrey has caused the biggest upset of the tournament thus far. The unseeded American took down fifth seed Russian Daniil Medvedev, showing his higher ranked opponent that he meant business. The result came after Medvedev narrowly escaped a five-set match in Round 1, and despite leading two sets to one in the Round of 64 clash, could not finish off Querrey, who triumphed 2-6 6-4 3-6 7-5 6-3.

He was the only seed to fall in the first day of the second round, as the procession of top 30 players continued into the Round of 32. But only five seeded players won through in straight sets, a refreshing change of just how close the competition is. Seventh seed Alexander Zverev had the quickest match of all, winning in less than 90 minutes to post a 6-2 6-2 6-0 victory over Argentinian Federico Coria, whilst Filip Krajinovic, Andy Murray, Pablo Carreno Busta and Hubert Hurkacz won their respective matches in straight sets.

At the top of the world rankings, second and third seeds Novak Djokovic and Dominic Thiem both dropped sets, with the Serbian world number two winning 4-6 6-1 6-3 6-1 after an early scare against Stefano Travaglia, whilst Thiem was challenged but shook off teenage Brazilian Thiago Seyboth Wild, 7-5 6-1 6-7 6-0. Roberto Bautista-Agut won in fourth sets against Taylor Fritz, whilst Nikoloz Basilashvili and Milos Raonic also dropped sets against French duo Jeremy Chardy and Hugo Gaston.

In other results, Karen Khachanov managed to avoid it being a day to forget for Russia, posting a five-set victory over Serbia’s Dusan Lajovic, 7-6 4-6 6-3 5-7 6-1. Other winners on day five were a trio of unseeded players, Guido Pella, Mikael Ymer and Nicolas Jarry. The Chilean qualifier Jarry had a particularly impressive win, downing Australian firebrand Nick Kyrgios in straight sets, 6-3 6-1 6-3.
