Chicago Sky are locked in as the No. 2 seed in the WNBA playoffs after the Las Vegas Aces clinch the top spot

LAS VEGAS — Chelsea Gray had 33 points, seven rebounds and nine assists, and the Las Vegas Aces wrapped up the Commissioner’s Cup for the best regular-season record in the WNBA by defeating the Seattle Storm 109-100 in a regular-season finale Sunday.

Kelsey Plum, who had 23 points for the Aces, scored seven points in the final minute. Her 3-pointer with 58 seconds left put Las Vegas up by six, and she added two more field goals as the Aces (26-10) clinched the top seed in the playoffs.

The Aces defeated the Chicago Sky and the Storm in consecutive games to clinch the top playoff spot, having defeated the defending champion Sky 89-78 on Thursday. The Sky will be the No. 2 seed in the playoffs.

The Storm already were assured of the No. 4 seed and will open the playoffs at home against the No. 5 Washington Mystics on Thursday.

The Aces’ opening-round opponent will be either the New York Liberty or Phoenix Mercury, pending the outcome of the Mercury-Sky game later Sunday.
