The first contestant, Joanne Kohlhagen of New Lenox, sent a puck right through the center slot.
Not to be outdone, Gayle Keller, a program coordinator from All Chicago, stepped up and slid one through the opening on the left side.
Things got more wild when Steve Dolinsky, a food critic from ABC7 in Chicago, made his attempt with a fluttering puck through the center hole.
Ivanovic, no stranger to pressure as the 2008 French Open champion, calmly stepped up and drained a shot through the left opening.
But if you thought this group was done, you'd be mistaken.
Kohlhagen and Ivanovic scored on their second attempts as well, both dead center.
It was the first time "Shoot the Puck" contestants went 4-for-4 and then scored two more since the game's inception, according to information provided by the team. Kohlhagen and Keller won cash prizes, while Dolinsky and Ivanovic were playing for charity.
The four contestants left the ice in triumph.
