Day two at Wimbledon saw Brits deliver and a big favourite tumble. Michael Hincks brings you three talking points from the first-round action, and looks at three things to look forward to when the second round gets under way on Wednesday…

Three today

Nadal and Delpo destined for showdown?

Rafael Nadal and Juan Martin del Potro are on a collision course to meet in the quarter-finals, and both opened up their campaigns with comfortable victories on Tuesday. World No 1 Nadal made light work of Dudi Sela, winning 6-3 6-3 6-2 out on Centre Court, while Del Potro also took exactly one hour and 50 minutes to dispatch Peter Gojowczyk in straight sets.

With 10th seed David Goffin crashing out, the chances of a Nadal-Del Potro meeting in the last-eight have increased, though 14th seed Diego Schwartzman and NextGen star Denis Shapovalov will be among those intent on making sure this encounter doesn’t come to fruition. But on today’s evidence, that will take some stopping.

Brits deliver

It was a great day for Britain’s greatest hopes, with the nation’s No 1s Kyle Edmund and Johanna Konta advancing to the second round without dropping a set.

Edmund progressed with relative ease by seeing off Australian debutant Alex Bolt 6-2 6-3 7-5, and though he goes on to play Bradley Klahn in the second round, the 23-year-old will already have one eye on a potential third-round meeting with Novak Djokovic.

Konta meanwhile made hard work of her win over Natalia Vikhlyantseva, with the 22nd seed prevailing 7-5 7-6(7) after converting her sixth match point. Former world No 4 Dominika Cibulkova will prove a very tricky customer for last year’s semi-finalist in the next round.

Big names tumble out

The women’s pre-tournament favourite is out. That somewhat unfortunate tag had been applied to eighth seed Petra Kvitova, the two-time Wimbledon champion, but she fell at the first hurdle in losing to Belarusian Aliaksandra Sasnovich in three sets – remarkably losing the decider 6-0 out on Court One.

Joining Kvitova in making an early exit is the men’s seventh seed, and French Open finalist, Dominic Thiem, who was forced to retire in the third set against Marcos Baghdatis. It means the draw becomes even sweeter for Djokovic, who also has Alexander Zverev for company in his quarter.

Three tomorrow

Return of the King and Queen

Roger Federer and Serena Williams return to action in the second round on Wednesday. The two 36-year-olds will be backed to overcome Lucas Lacko and Viktoriya Tomova without a hitch, but that could be where the easy games end for the imperious duo.

Serena could face Kristina Mladenovic in the third round should she overcome qualifier Tomova, while Federer could meet Ivo Karlovic in the third – one of umpteen big-servers in the Swiss’ half of the draw.

Swan on song again?

British wildcard Katie Swan produced a stunning performance on Monday to beat world No 36 Irina-Camelia Begu 6-2 6-2, and the 19-year-old will be out to claim a seeded scalp on Wednesday when facing No 29 Mihaela Buzarnescu.

Swan is ranked 204 in the world, and she could double her career prize money in reaching the third round. But it’s not just about the £100,000 – a meeting with either Karolina Pliskova or Victoria Azarenka is also on the line if she can beat Buzarnescu.

Can Stan continue to be the man?

Stan Wawrinka winning is never normally a shock, but it can be on grass, and most certainly was after he lost the first set 6-1 to sixth seed Grigor Dimitrov on Monday. The Swiss somehow responded with two tie-break victories and a 6-4 showing in the fourth to send the Bulgarian packing, and having displaced Dimitrov in the draw, Wawrinka will be eyeing a run deep into the tournament.

Few would have predicted it, especially after his Eastbourne exit to Andy Murray last week, but now Wawrinka has qualifier Thomas Fabbiano to overcome in the second round. This time, the boot will be on the other foot, with the three-time Grand Slam champion expected to progress.
