Now that the first round of the Davis Cup has come to an end, it is time to resume the lead up to two Masters Series tournaments on the hard courts of the United States in the middle of March. Each week from now until then, we will see on average two hard court tournies played along with one on clay court. Gotta keep those clay court specialists busy too! Here's who to look out for this week on tour.

Marseille, France

Injuries or illness among the contenders in this field will have a major impact on who comes out on top. Number one seed Novak Djokovic would be the heavy favourite except for the fact he didn't even make it through his Davis Cup rubber against Russia last week due to a stomach virus. I wouldn't be surprised if he wasn't yet ready for tournament play. Andy Murray is also in the top half of the draw, but questions of his health are also present. He did not even suit up for Great Britian in their tie versus Argentina in the Davis Cup.

The bottom half of the draw includes an interesting potential matchup between Marcos Baghdatis and Mikhail Youzhny. An all-French quarter final matchup could also involve Jo-Wilfried Tsonga vs Richard Gasquet in a rematch of their Aussie Open fourth round. Two names lurking in this section of the draw who are returning after a long layoff are Mario Ancic and Robin Soderling. Lookout for either of these two to cause some 'upsets'.

Final: Murray vs Youzhny

Delray Beach, United States

Not too much to get excited about in this hard court tuneup. James Blake goes in as the heavy favourite in the top half. Also lurking around are Americans Mardy Fish and Robby Ginepri. I wouldn't bank on either of these two, especially Ginepri whose game has gone south since the US Open in 2005.

The bottom half of the draw has over the hill Vince Spadea perhaps meeting under the hill Sam Querrey. Back from injury is German Tommy Haas, who I would call the tournament favourite if healthy. Belgian Xavier Malisse should also be tough if he's feeling healthy. And don't forget the future of American tennis, Donald Young who is also testing the waters in Delray Beach.

Final: Blake vs Haas

Costa do Sauipe, Brazil

Ok, for all your clay-courters out there we have some tennis on the red dirt this week as well. The usual suspects will be out in full force in Brazil this week. Top half includes Carlos Moya who I'm sure is looking for a good result to get him going. Also Jose Acasuso and Augustin Calleri are up here. In the bottom half, there are some less impressive names like Montanes and Starace. Be on the lookout for Gustavo Kuerten's foray into the game again on his farewell tour. Also some bigger names like Volandri and Almagro are to be wreckoned with. And I'll throw this name in as well, although expectations are non-existant...Guillermo Coria.

Final: Acasuso vs Almagro
