Allie Quigley scored 20 points and the Chicago Sky withstood a threat from the Phoenix Mercury in the fourth quarter before pulling away in an 89-71 victory Wednesday night at IMG Academy in Bradenton, Fla.
Kahleah Copper's 16 points, Courtney Vandersloot's 12 points and five assists and Azura Stevens' 10 points also gave the Sky a boost as it avenged a 10-point loss from last week.
Chicago was coming off a blowout setback to Seattle two nights earlier, but its defense was stiffer against the Mercury.
The Sky ended up 1-for-11 from 3-point range, but it had enough offensive sources to make up for some shoddy shooting stretches before posting a 54.7 percent shooting mark from the field. A 38-26 rebounding edge also helped.
Sophie Cunningham and Skylar Diggins-Smith scored 15 points apiece for Phoenix, while Bria Hartley added 13 points off the bench and Shatori Walker-Kimbrough finished with 10 points.
Phoenix center Brittney Griner, who scored 22 points in the previous matchup with Chicago, was held to nine points on 3-for-11 shooting from the field.
The Mercury, which lost for just the second time in its last seven games, made a push by beginning the fourth quarter on a 9-2 run to close to within 66-59 on Cunningham's 3-pointer. An 8-0 response by the Sky later in the quarter helped put the game out of reach.
Quigley scored Chicago's first eight points of the third quarter as the Sky stretched its margin to 50-40. Then her teammates became involved in what was a 10-0 spurt for the Sky as the lead grew to 56-40.
The Sky tallied six points in the final minute of the third quarter to hold a 64-50 advantage.
Chicago scored eight points in the final 1:30 of the first half for a 42-36 edge at the break despite a 1-for-8 mark on 3-point attempts.
Earlier, the Sky made only nine of its first 26 shots from the field, yet led 23-18.
