Geekie's second goal on the power play pushed the lead to 4-0 at 8:50 of the second period. Rinne stopped Geekie's wrist shot, but the rebound went in off Ekholm's skate.
The 22-year-old rookie was assigned to the Chicago of the American Hockey League for two games in February and scored four goals and an assist.
"He's a very mature guy," said Bean, who played two seasons in the AHL with Geekie. "He took it really well. Obviously, he took his time in the American League and took full advantage of it to get confidence, and it showed tonight."
Martin Necas made it 5-0 on the power play when he redirected Svechnikov's pass to the slot at 4:38 of the third period. Rinne was pulled after the goal.
"I thought five was enough," Hynes said. "[Rinne] made some big saves later in the second, but after five with that much time left in the period, it was an opportunity to give him a break and give [Kaskisuo] an opportunity to come in and play."
Cousins scored on a wrist shot to make it 5-1 at 15:28.
