CHICAGO -- Courtney Vandersloot became the seventh player to have a triple-double in WNBA history, finishing with 13 points, 10 rebounds and a career-best 15 assists in the Chicago Sky's 114-99 victory over the Dallas Wings on Friday night.

Vandersloot set a franchise record with 10 first-half assists and tied her team mark of 14 midway through the third quarter. Ticha Penicheiro holds the league record with 16, which she accomplished twice -- in 1998 and 2002.

"It is a big deal," Vandersloot said. "This is my first ever triple-double. ... I can't rebound like that."

She's the first Sky player to accomplish the feat.

Kahleah Copper scored a career-high 23 points on 9-of-10 shooting to help Chicago (8-16) snap a four-game losing streak. Allie Quigley added 21 points as the Sky scored the most points in franchise history, topping 107.

Dallas center Elizabeth Cambage's consecutive games with 35-plus points came to an end after being double-teamed for much of the game. She finished with 23 points for her 13th 20-point game of the season.

Skylar Diggins-Smith added 21 points for Dallas (14-10), and Azura Stevens had 14 points and a career-high nine rebounds. Dallas coach Fred Williams was ejected for the second time in the last three games.
