(AP) — Corey Crawford earned his second shutout of the season in the Chicago Blackhawks' 3-0 win over the Florida Panthers on Thursday night. Crawford stopped 20 shots by a sluggish Florida offense, which took only four shots in the first period and didn't take its fifth shot on goal until 10:47 of the second. Duncan Keith made a nifty pass from the slot to Saad in the right circle, He shot past Luongo on the glove side early in the second period. The Panthers hope to change their offensive woes with the acquisition of 22-year veteran forward Jaromir Jagr, the league's oldest player.
