Jaroslav Halak, the Blues goalie, acquired from Montreal after leading the Canadiens to the Eastern Conference Finals made 30 saves in his first win at home in a 4-1 final over the Chicago Blackhawks.

After Ben Smith scored 7:59 into the second period to give the Hawks a 1-0 lead, the Blues finished strong tying the game on David Perron’s goal at 10:15 of the second period. T.J. Oshie had the game winner 17:01 and Matt D’Agostini scored early in the third period to make it 3-1.

After Halak stopped a penalty shot, Alex Steen scored on an empty net with 1:37 left to give the Blues their fourth win in six games. Perron and Steen have four goals each in the Blues’ six games.
