Preview: Monday's action from Miami is packed with big name match-ups throughout the day and night.
The highlight comes in the night session with Roger Federer taking on Andy Roddick in the third-round of the Men's ATP Masters 1000 event.
Federer has been in scintillating form, as he demonstrated when he won the big title in Indian Wells eight days ago. While Roddick has fallen to No. 34 in the rankings, these two have had some memorable meetings down the years, not least their epic Wimbledon final in 2009 where Federer prevailed 16-14 in the final set.
But with Roddick 2-21 lifetime against Federer and 1-13 against top-10 players since August 2010, the chances of the American previaling appear slim.
Earlier in the day on the men's side Novak Djokovic will be taking on his fellow-Serbian Viktor Troicki. Just as with Roddick, all the statistics point toward a comfortable win for the higher-ranked player.
Troicki has lost the last 10 matches to Djokovic and has also lost 21 in a row against top 10 players.
For an evenly-matched contest between two players with the ability to compete with the very best don't' miss Juan Martin Del Potro going up against Marin Cilic. The showdown is a repeat of the 2009 US Open quarter-final, which Del Potro won on the way to claiming his first grand slam title.
There is no let up in the action in the WTA Tour event either on Monday. Both Williams sisters will be competing in fourth-round action, looking to show they are still players to fear in the women's game.
Serena will also be out for revenge when she goes up against Sam Stosur in the second match of the day on Stadium court. The Australian shocked Serena to win her maiden grand slam at the US Open last year in an ill-tempered affair.
In the last match of the night session, Serena's sister Venus will face Ana Ivanovic, in a battle of former world No. 1s.
Ivanovic looks to finally be getting back to her best following a semi-final run in Indian Wells earlier in the month. Venus, playing in her first tournament since last year's US Open has already caused an upset in defeating Wimbledon champion Petra Kvitova.
A 7-1 winning record over Ivanovic will give Venus confidence that she can progress even further.
The day's play is opened up by Maria Sharapova, while her conqueror in the final of both Indian Wells and the Australian Open, Victoria Azarenka, will also in fourth-round action.
