Williams beats Halep to win WTA Finals title (Yahoo Sports)

Serena Williams beat Simona Halep 6-3, 6-0 on Sunday to win her third-successive title at the WTA Finals and her fifth overall. Halep easily beat Williams just four days earlier during the group stage of the tournament, but Williams turned that around with an aggressive game plan that unsettled the Romanian player. Williams won 11 of the last 12 games in the match to join Martina Navratilova and Steffi Graf as the only players to have won five titles in the season-ending championships. The match was the most one-sided championship match in the WTA Finals since Kim Clijsters beat Amelie Mauresmo 6-2, 6-0 in 2003.
