ATLANTA -- Angel McCoughtry matched a season high with 33 points, Tiffany Hayes hit the clinching free throws with 29 seconds remaining and the Atlanta Dream beat the Chicago Sky 81-79 in overtime Sunday for its fourth straight victory.
The Dream (15-5) looked sluggish after winning Saturday night at Indiana, shooting a season-low 35 percent from the field and finding it difficult to put away a Sky team that has lost five straight and 12 of 15.
Allie Quigley finished with a career-high 27 points in a reserve role, and Sylvia Fowles, who missed a layup at the regulation buzzer that would have won the game, had 17 points and 14 rebounds for the Sky (8-13).
"Stupid stuff gets you beat," said Sky coach Pokey Chatman. "We literally have a segment of video that says that. Until we stop aiding in our demise, the hole is going to get deeper."
Sancho Lyttle scored 12 points and 13 rebounds, and Erika de Souza added 8 points and 11 rebounds for Atlanta.
Hayes, who had a season-high 21 points the night before, finished with 17. She hit the winning foul shots after Sky forward Jessica Breland threw the ball away with 40.6 seconds left in overtime.
The Sky, which lost by 38 on the road in Atlanta last month, took its biggest lead at 11 on Fowles' 3-point play with 6:23 left in the second quarter. But the Dream came back to lead by a point on McCoughtry's layup at the 8:38 mark of the third.
McCoughtry had 9 points in the third to help the Dream outscore the Sky 17-9. A technical foul on Chatman led to McCoughtry hitting the ensuing free throw and scoring her 20th point one possession later on a fastbreak alley-oop pass from Celine Dumerc.
The Dream didn't trail in regulation after de Souza's layup made it 50-49 at the 6:17 mark of the third, but a free throw by Tamera Young put the Sky up by 1 early in OT.
