KalPa dropped a a 5-4 decision to Ässät on Saturday, in a game in which the KalPa website mentions something about "Saturday Shirts and Leather Pants". I have no idea what that means, so either Google translator is lost, or some interesting stuff went down yesterday.
Hartikainen had a pair of assists and four shots on goal. He's got 8 points in 12 games thus far and he's up to 29 shots in 12 games with only 1 goal, so expect him to snap out of that soon.
From the lineup page, it appears that Hartikainen played on the third line.
