With all the seeds and big names falling around them, top two seeds Novak Djokovic and Andy Murray have held their nerve and cruised through the rounds at Wimbledon 2013 to make the quarter-finals.
Neither man has dropped a set up to this point, but their tasks are about to get significantly more difficult on quarter-finals Wednesday.
Djokovic is first out onto No.1 Court in his match with Czech Tomas Berdych in a repeat of their Australian Open quarter-final from earlier this year.
The Serb came out on top in four sets in that match, but the seventh seed got best of his opponent the only time they met on grass in the 2010 semi-finals when Berdych went on to lose to Rafael Nadal in the final.
Djokovic is in terrific form, however, and Berdych has not played his best tennis in getting to this stage, so anything but a win for the 2011 champion would be another huge shock.
Follownig that clash on No.1 Court will be an historic match as Poland’s Jerzy Janowicz and Lukasz Kubit become the first two of their countrymen to have made a Grand Slam quarter-final in the same year.
Kubot has battled well to make it this far but 24th seed Janowicz is the favourite to progress, with his huge serve and power hitting making him a particularly dangerous opponent on grass.
The winner of that match will become the first Pole to make the Wimbledon semi-finals and will be facing the man that comes out on top in the second match on Centre Court.
Andy Murray is heavy favourite to over come unseeded Fernando Verdasco, but he has stated he is not about to get complacent, what with the upsets that have gone before.
The British number one has been training with left-handers in preparation for the match and expects a tough test.
Verdasco is more comfortable on other surfaces, but his whipping forehand can cause problems and, crucially, he is on his best run of form this year.
Murray will have the Centre Court crowd behind him, however, and he should prove too much for the Spaniard.
First up on Centre Court will be another intriguing match-up between eighth seed Juan Martin del Potro and number four seed David Ferrer.
Despite his higher ranking, the French Open runner-up is probably not the favourite to win this match, as his game is not particularly suited to grass court tennis.
Ferrer’s best performance at Wimbledon was the same stage last year and he will find it extremely difficult to compete with Del Potro’s big serving and huge groundstrokes, with the surface making them even more effective.
However, Ferrer is improving and his Argentine opponent has yet to be tested at this year’s tournament, which may be to do with the level he is playing at.
The players will step out on court at 1pm, so the Murray vs Verdasco and the Kubot vs Janowicz matches are expected to start at approximately 4pm.
Weather does not look to be an issue after yesterday's rain, as the day is expected to be more overcast and cooler than recently, though no rain has been forecast until later in the day – so expect a full day of thrilling tennis.
