The Sony Ericsson WTA Tour recently launched a new statistic, entitled the “Sony Ericsson WTA Tour Power Index.” This statistic represents a totaled analysis of a player’s fastest shots during a match including: first and second serves, groundstroke (forehand or backhand), first and second-serve returns and smash/volley. The final Power Index “score” is an average of all six individual statistics.
Venus Williams topped the Sony Ericsson WTA Tour Power Index after Week One at the Acura Classic in San Diego with 98.8 mph. Yaroslava Shvedova holds the record after three weeks, recording 102.9 mph to top the charts at the East West Bank Classic in Los Angeles. Following the Rogers Cup in Toronto, Nadia Petrova recorded the highest Power Index for the week at 93.3 mph. Each player’s Power Index reflects their personal best for the week (and cumulative below), reflecting the highest recorded Power Index per match and only recording matches on center court.
