PHOENIX (AP) — Brittney Griner dunked while scoring 29 points, Diana Taurasi had eight of her 20 points in overtime and Phoenix Mercury evened the WNBA Finals with a 91-86 win over the Chicago Sky. Griner kept the Mercury within reach of Chicago during a sluggish start and brought the Phoenix Suns players sitting courtside to their feet with her second career playoff dunk in the first quarter. She scored on a turnaround jump to help give Phoenix a late four-point lead in regulation, but just missed blocking Courtney Vandersloot’s tying layup with 4.4 seconds left. Taurasi opened overtime with a four-point play and added a 3-pointer that put Phoenix up 89-86 with 1:24 left. Skylar Diggins-Smith, who had 13 points and 12 assists, sealed it on a layup with 12.8 seconds left.
