Cheyenne Parker had career highs with 15 points and 10 rebounds, Cappie Pondexter scored 15 points, and Courtney Vandersloot added 11 for Chicago (10-12).

Seattle's Sue Bird made a short jumper and then a 3-pointer to cap a 14-2 run that made it 88-all with 18.9 seconds left, but Delle Donne dribbled the clock down before pulling up, in front of the out-stretched arm of Breanna Stewart, from near the top of the arc to win it.
