ATLANTA -- Riquna Williams scored 23 points, hitting five 3-pointers, and Nneka Ogwumike added 17 points and 15 rebounds to help the Los Angeles Sparks beat the Atlanta Dream 76-71 in overtime on Sunday.

Kalani Brown, the No. 7 overall pick in April's draft, tied her season-high with 12 points and Chelsea Gray added 10 points and nine assists for Los Angeles.

Atlanta used a 9-2 run to close regulation and open the extra period to take a 67-64 lead with three minutes to play. Elizabeth Williams made 1 of 2 free throws to open the scoring in overtime and give the Dream their first lead since late in the first half before Tiffany Hayes made a short floater to cap the spurt. Williams made back-to-back 3-pointers to give the Sparks a three-point lead with 1:29 remaining and the Sparks led the rest of the way. Her steal with 31.3 seconds left, and Gray's pull-up jumper 20 seconds later, sealed it for Los Angeles.

Hayes led the Dream with 24 points, including a driving layup with a second left in regulation that forced OT. Alex Bentley scored 12 points and Monique Billings added nine points and a career-best 16 rebounds.

The Dream made just 2 of 19 (10.5%) from 3-point range.

The Sparks have won five of their last six games.
