The Russian, who had risen to as high as No. 3 in the world, appeared mired in a terminal decline. He was struggling desperately for form and failing to find any kind of consistency.
Davydenko often looked listless and dispirited, leading to speculation that he may be close to calling time on his career.
However, a four-month injury layoff seems to have rejuvenated Davydenko's spirits and last week he clinched back-to-back titles, winning in Umag, Croatia, to follow his German Open triumph.
Now back at No.8 on the official list, Davydenko comes in at No.7 on the Yahoo! Sports Power Rankings, our list of who's hot and who's not in the men's game.
