Duluth would finally crack Ruddock less than a minute into the third period on a goal from Maria Rooth, a perennial Crimson killer. But that was all the Bulldogs could manage.

Though the powerplay got the goals, Ruddock’s performance was the difference.

“She came up huge in key situations,” Ruggiero said. “She earned us our W.”
