Roger has been on top for 214 consecutive weeks but his balance there is a little off right now.
Justine was there most of last year. She dropped out for a little while in the beginning of the year.
Will either one drop out even for a brief period this year? and who will take their place?
Nadal and Djokovic of course have a shot in points and with the clay court season coming up Rafa looks pretty good. Murray and Nalbandian would have to be considered and who else?
For the women, Maria hasn't lost yet this year and looks great. The Williams seem more serious about giving it a go. Davenport has a chance and of course those serbian ladies Jelena and Ana. Anyone else have a shot?
