After giving up 16 goals in less than seven periods of work in his first three starts with the Penguins, goalie Antti Niemi was placed on waivers Monday afternoon. If he is not claimed by noon Tuesday, coach Mike Sullivan said the ideal scenario would see the 34-year-old Finn assigned to Wilkes-Barre/Scranton of the AHL to work on his game. “That would be a great option, to give him an opportunity to get in some ideal circumstances and give him an opportunity to build his confidence in an environment that's not as high stakes as the one we're in here,” Sullivan said. If Niemi is sent down, the Penguins would likely call up 22-year-old Tristan Jarry or 26-year-old Casey DeSmith to take his place.
