Miami Second Round, Part 2

While the seeds did fare slightly better in today's action, with only four falling rather than five, it still featured one major, major upset. Mardy Fish bucked the trend of American players underperforming by ousting a lackluster defending champion Andy Murray in straight sets. Despite making the finals at the Australian Open earlier this year, Andy Murray has not had the year he was hoping for, and to finish off the first hard court swing of the tour on such a sour note is not going to be encouraging.

Mardy Fish, on the other hand, really needs to build on this victory. Unfortunately, his section of the draw is still killer. He'll face Feliciano Lopez next, and if he can get through that, he'll get the winner of the toughest third-round match in the draw, which features Youzhny and Wawrinka. Fish will need them to wear each other out, unless he really is playing at his best. But beating a top player on an off-day is different than making a deep run, and he'll need to be consistent in order to do that.

The other upsets of the day were less surprising. Gilles Simon and Albert Montanes lost, as did Janko Tipsarevic. But none of them were picked as potential winners of the tournament, so Andy Murray is the real shocker of the day. The upset bug continues to be the story around the ground for a second tournament in a row.

Looking ahead to tomorrow's play, it's tough for me to see as many upsets in the cards, if only because there aren't that many seeds even left to upset. There are matches that could go either way, and feature some excellent players, so I suggest checking them out if you can. Rafael Nadal and David Nalbandian play on center court tomorrow, and if Nalby was ranked as high as he should be, that would be at least a quarterfinal. They have had a good rivalry in the past, and Nalbandian's loss to Nadal at last year's Indian Wells tournament was a thriller. It'll be interesting to see how healthy the Argentine really is in tomorrow's match with Nadal.

Some of the upsetters from the previous round need to see if they can go one further tomorrow, as Olivier Rochus takes on Tomaz Bellucci, and Jeremy Chardy faces Nicolas Almagro. There are also two very interesting matches tomorrow which are mirror images of each other, even though the players facing each other in each match are polar opposites. John Isner takes on Juan Carlos Ferrero while Ivo Karlovic faces David Ferrer. These could be very similar matches, as they appear to be on the surface.

Both Belgians are also in action, and they're both hoping to have a deep run, as they're not going to get many more tournaments this year that don't feature Serena Williams. Also, look for Andy Roddick and JW Tsonga to get through their matches without too much trouble. Or perhaps not - maybe the upset bug as a few matches to tip against the favorite?
