Martin Hanzal scored at 9:29 of overtime to lift the host Phoenix Coyotes to a 3-2 win over the Chicago Blackhawks in Thursday's opener of their Western Conference quarterfinal series.
Hanzal redirected Adrian Aucoin's shot from the right point past Corey Crawford for the dramatic victory.
Taylor Pyatt and Antoine Vermette scored second-period goals and Mike Smith turned aside 43 shots for the Coyotes, who were 14.2 seconds away from winning in regulation when Chicago's Brent Seabrook forced overtime.
Phoenix survived that crushing goal and the loss of leading goal scorer Radim Vrbata early in the first period to beat the Blackhawks for the fourth time in five meetings this season.
Blackhawks captain Jonathan Toews made an electrifying return to the lineup with a goal and an assist, scoring on his second shift after missing the final 22 games of the regular season with a concussion.
