The battle for supremacy at the top of men's tennis has rarely been more electrifying, but you wouldn't know it from the static offerings spit out by the ATP rankings computer each week.
While the rankings system is fair and rewards performance over a 12-month period, it does not always give an accurate reflection of current form. Changes at the top are few and far between, primarily because of the weight of points on offer at the Grand Slams.
Each Tuesday, starting this week, Yahoo! Sports will give our take on who is hot and who's not in power rankings aimed at providing a more up-to-date form guide on tennis' movers and shakers.
We will alternate between the ATP and WTA Tours. This week, we kick things off with a familiar name at the top of the men's pile.
