Gustafson scored the first four points of the fourth quarter to get Phoenix within a point, but Gray scored five straight points as Las Vegas extended the lead to 60-51.

Young’s 3-pointer gave the Aces their first lead at 19-18, and the hosts held a 21-20 advantage at the end of the first quarter.

The lead changed hands twice at the start of the second quarter before Gray’s 3-pointer completed a 9-0 run that gave Las Vegas a 30-22 lead.

Young’s 3-pointer gave the Aces their biggest first-half lead at 35-24 before Peddy made consecutive 3-pointers and assisted on a Cunningham basket as Phoenix pulled within 42-37 at halftime.
