Troy Brouwer tapped in his own rebound to snap a third-period tie and the St. Louis Blues advanced to the second round of the playoffs for the first time in four seasons, eliminating the defending Stanley Cup champion Chicago Blackhawks 3-2 in Game 7 of their Western Conference quarterfinals series Monday night.

Brouwer, who played for the Blackhawks' Cup winner in 2010 and was among the veteran additions to a team trying to break through, swiped in a backhander. The goal at 8:31 was his first in 24 postseason games since 2013.

Jori Lehtera scored his first career playoff goal and rookie defenseman Colton Parayko also scored for the Blues, who avoided another inglorious finish. They led 2-0 early before the Blackhawks tied it in the second period.

Chicago just missed a chance to tie it when Brent Seabrook's shot went off both posts with about 3:30 left.
