SEATTLE (AP) -- The Chicago Sky got off to a slow start. However, once they got going, there was no stopping them.
Epiphanny Prince scored 12 of her 16 points in the fourth quarter as the Chicago Sky rallied from 16 points down in the second half to beat the Seattle Storm 79-66 on Thursday night.
Swin Cash scored 18 points against her former team, Sylvia Fowles had 16 points and 10 rebounnds and Allie Quigley added a career high-tying 14 points for the Sky (16-8). Chicago, playing without injured leading scorer Elena Delle Donne, used a 17-0 run in the fourth quarter to avoid the two-game season sweep by Seattle.
''It was a great effort,'' Prince said, ''but I think we should have started earlier.''
Prince scored seven points during the 17-0 fourth-quarter run that saw the Sky go from 13 points down to a 66-62 lead. Chicago outscored Seattle 32-6 in the fourth quarter and 30-4 over the final 8 1/2 minutes.
''If felt so good,'' Cash said of the 26-point swing in the fourth quarter. ''We felt our shots going in; we were focused - and it came at a good time. That's the momentum we need, and the focus we need, come playoff time.''
Shekinna Stricklen scored 20 points to lead Seattle (10-13).
The Storm used strong shooting and a 12-1 third-quarter run to take a 56-40 lead before the Sky got going. Seattle was shooting 25 for 46 through the third quarter but went just 3 for 12 in the fourth.
''We tried to stop it, but they got on a roll,'' said Storm veteran Tina Thompson, who scored just seven points on 3-for-10 shooting. ''And once they did, especially Epiphanny, it was just kind of hard to stop them.''
Delle Donne wore a boot on her left foot while watching from the bench in street clothes. She suffered the injury in the first half of Tuesday's game at Los Angeles.
Without its star rookie, Chicago got off to a slow start while Seattle jumped out to a 39-29 halftime lead. The Storm made 14 of their first 25 shots, while Chicago struggled from the field and missed all five of its 3-point attempts.
''It's not always an immediate fix right after somebody goes down,'' Cash said of how the Sky struggled through the first three quarters. ''We got a little more aggressive, and we got some stops. . We have the ability to go in spurts.''
Turnovers on Seattle's first three possessions of the second half helped Chicago pull to 39-35 over the first 1:01 of the third quarter, and the Sky eventually scored on its first five possessions after halftime. But the Storm kept shooting well, making eight of their first nine field goals and three 3-pointers over the first 7 minutes of the second half to open up a 58-43 lead. Along the way, Seattle's advantage got as large as 16 points.
But Chicago shot 12 of 15 from the field and 2 for 2 from 3-point range in the fourth quarter to extend its winning streak to three games.
