WNBA Defensive Player of the Year
The Women's National Basketball Association's Defensive Player of the Year Award is an annual Women's National Basketball Association award given since the league's inaugural season -- 1997, to the top defensive player of the regular season. The winner is selected by a panel of sportswriters and broadcasters throughout the United States, each of whom casts a vote for first, second and third place selections. Each first-place vote is worth five points; each second-place vote is worth three points; and each third-place vote is worth one point. The player with the highest point total, regardless of the number of first-place votes, wins the award.
Tamika Catchings has won the defensive player of the year award more times than any other player with the record of 5.
