Rookie Elena Delle Donne scored 23 points and the Chicago Sky routed the New York Liberty 75-55 in a matinee game on Thursday.
The win gave Chicago sole possession of first place in the Eastern Conference. It's the latest that the Sky (11-4) have been in first since the team came into the WNBA in 2006. Chicago is still looking for its first trip to the postseason.
The Sky did it without starting center Sylvia Fowles, who missed the game after aggravating a right ankle sprain in Chicago's win over Connecticut last week.
Chicago jumped all over the Liberty, building a 13-0 lead early in the game and never looked back.
Plenette Pierson and Kelsey Bone each scored 11 points to lead New York (6-9), which has dropped five of its last six games.
