Courtney Williams had 12 points, 13 assists, and 11 rebounds to log the first triple-double of her career and Alanna Smith scored 18 points as the host Chicago Sky topped the Los Angeles Sparks 86-78 on Friday to sweep a back-to-back.

Chicago (7-9) led by as many as 17 points and held on as the short-handed Sparks whittled the deficit to single digits midway through the fourth quarter and again down the stretch.

Los Angeles made it a six-point game with 1:15 left behind an 11-0 run.

Azura Stevens (15 points) and Nneka Ogwumike (14) led the way for the Sparks, who fell to 7-9 after losing for the fifth time in seven games. Dearica Hamby had 12 points and 12 rebounds.

Kahleah Copper chipped in 17 points for Chicago, while Marina Mabrey (15) and Elizabeth Williams (12) followed.

Chicago built separation with an 11-0 run in the first 3:08 of the third quarter. Courtney Williams capped the spurt with a running pullup jumper. Los Angeles didn’t record its first points of the quarter until an Ogwumike layup 19 seconds later.

Los Angeles made a comeback attempt with only eight available players, as point guard Jordin Canada left the game with a shoulder injury after contributing seven points and four assists in 15:37. Chiney Ogwumike (foot) missed the game.

Karlie Samuelson (11 points) and Zia Cooke (10) also finished in double figures for the Sparks.

Mabrey’s scorching first half paced the Sky to a 43-38 lead at intermission. Her 13 points on 4-for-5 shooting included going 3-for-3 from long range. Copper followed with nine points.

The Sky shot 65.4 percent in the first half (17-for-26). While the Sparks shot just 36.8 percent (14-for-38), they stayed within two possessions of Chicago thanks in part to forcing 10 Sky turnovers while enjoying a plus-three advantage on the glass.

Ogwumike scored 12 first-half points to lead the Sparks.

Chicago, which defeated visiting Los Angeles 80-63 on Wednesday, took a 2-1 advantage in the season series. The Sparks will host the Sky on Aug. 29.
