PHOENIX (AP) — DeWanna Bonner scored eight of her season-high 34 points in overtime and the defending champion Phoenix Mercury rallied to beat the Chicago Sky 89-87 on Tuesday night in their first meeting since last year's WNBA Finals. Chicago's Elena Delle Donne missed a jumper with 13 seconds remaining in OT and grabbed her own rebound, but Brittney Griner blocked her putback attempt.
