For the most part, the ATP & WTA rankings do a fine job of determining which players performed the best throughout the calendar year. The rankings showcase who’s had the best results in the past year, but not necessarily who the best players are right this moment.
When it comes to analyzing and predicting matchups, tournament seeding, players returning from injury, and many other factors, rankings can be very deceiving.
Take Vasek Pospisil for instance. The 29-year-old was ranked as high as No. 25 in 2014, but struggled mightily with a back injury for most of the last three years. Over a year removed from a herniated disk operation, Pospisil is finally healthy, and currently shredding through ATP draws. Since October, Pospisil has beaten Diego Schwartzman, Karen Khachanov, Reilly Opelka, Fabio Fognini, Denis Shapovalov, David Goffin, Daniil Medvedev and Hubert Hurkacz.
Pospisil is currently ranked No. 93 in the world. With that ranking, he’s a land mine in every draw until his ATP ranking finally gets high enough to grant him a seeding. Based on his current UTR rating, which pegs him as the world’s 14th best player, that might take a while.
