CHICAGO — Seattle couldn’t overcome a slow start, falling behind by so much early in the game that even 17 consecutive points didn’t make a difference as the Storm lost 78-71 to the Chicago Sky in WNBA action Sunday night.

Chicago got off to a strong start, leading 29-16 after one quarter and 43-17 early in the second but Seattle scored 17 consecutive points and closed with 44-34 at the half.

‘‘We turned it over, and it gave them fast-break points and points in the paint,’’ Chicago coach James Wade told the Chicago Sun-Times. ‘‘And it actually helped them get back in the game and kept the game competitive. I think if we don’t turn the ball over, it’s hard for them to get back into the game.’’

The Storm was as close as six in the third quarter, but a 9-0 Chicago run early in the fourth quarter pushed the lead to 71-55.

Cheyenne Parker came off the bench and scored 18 points with 11 rebounds for Chicago.

‘‘She dominated the game,’’ Wade said. ‘‘That’s what we needed from her. She works hard. We just want her to reward herself by seeing it out there when she’s on the floor during game time.’’

Stephanie Dolson added 15 points and Kentwood High graduate Courtney Vandersloot had 11 with seven assists for the Sky (2-2), which had its best defensive game of the season after giving up 105 in its last outing.

The defending champion and short-handed Storm (3-3) continued its pattern of following a victory with a defeat, with all three setbacks on the road. Natasha Howard and Jewell Loyd had 20 points apiece.

Seattle shot 38% and was 3 of 18 from three-point range. Chicago, which had 20 turnovers, had eight three-pointers but only had eight points from the foul line while the Storm was 16 of 19. The Sky also had a 45-22 rebound edge.
