By Doug Feinberg | The Associated Press(AP) – Las Vegas Aces star A’ja Wilson is in a class by herself, winning the WNBA MVP for an unprecedented fourth time. For the second consecutive season, Wilson averaged at least 20 points, 10 rebounds, 2 assists, 2 blocks and a steal per game. She is the only WNBA player to reach these averages in a season while playing at least 15 games. Players were awarded 10 points for a first-place vote, seven points for a second-place vote, five points for a third-place vote, three points for a fourth-place vote and one point for a fifth-place vote. ___This headline has been corrected to show that Wilson was the unanimous choice last season but not this season.
