Katie Douglas scored 15 points and had five rebounds to lead the Indiana Fever over the Washington Mystics 83-51 on Sunday.
Jessica Davenport scored 14 points and had five rebounds and Tamika Catchings scored 13 points with eight rebounds for the Fever, who lead the Eastern Conference by two games.
The Fever limited the Mystics to 35.2 percent shooting and forced 19 turnovers. The 51-point performance is the third-lowest total in the league this season and Indiana's 31-point victory margin was the second-largest.
"Our defense was very disruptive," Fever coach Lin Dunn said. "We spent lots of energy with our press. It was a good win over a good team."
Douglas broke out of a slump with her most points since scoring 20 on July 13.
"You're just going to have up and down moments and thankfully I was able to get on track tonight," Douglas said. "I was just happy we were able to have such a big win and I think we were doing some great things on the defensive end and on the offensive end. When we start playing well on both ends of the floor, we're a hard team to beat."
Crystal Langhorne scored 11 points and had seven rebounds and Jasmine Thomas scored 11 points for the Mystics, who have lost five straight games.
The Fever improved to 4-0 this season against Washington, racing to a 14-2 lead to start the game and building a 79-47 lead at one point late in the fourth quarter.
"They totally outplayed us," Langhorne said. "We have lost games, but this one was bad. We need to play harder and not turn the ball over. Things weren't pretty."
