But he clearly still has the talent to make some spectacular saves, and that's exactly what he did against the on Sunday evening. Late in the first period, Bobrovsky exploded from one post to another to rob of what looked like a sure goal as the play was developing. BB Florida Panthers (@FlaPanthers) What I love about this save is that there was one Panther not puck-watching, and lucky for them, it was the goalie. Unlike the skaters in front of him, Bobrovsky read the play perfectly, anticipated the backdoor pa s and slid acro s just in time to shut it down.

Toronto Maple Leafs (@MapleLeafs) With a goal and a sist, Marner now has 30 points over the life of his 22-game point streak. He simply cannot be stopped. Mikko Rantanen gives St. Louis the For much of Sunday's Central Division showdown between the and St. Louis Blues, there wasn't much offense. Then Mikko Rantanen gave the Avs a 1-0 lead in the second period and answered with a power play goal eight minutes into the third. Late in the third period is when the fireworks really began for both sides. Blues forward took a late interference penalty, and the lethal Avalanche power play had an opportunity to win the game against a Blues penalty kill that ranked 32nd in the league. However, decided that the best defense is a good offense. The Avalanche turned the puck over in the neutral zone, and Saad out-muscled for the loose puck before firing it past to give the Blues a 2-1 lead with 96 seconds left in regulation. Avs power play... right? St. Louis Blues (@StLouisBlues) That could have been a back-breaking play for the Avs, but instead they dialed the pre sure up to 11 in the waning moments of the third period.
