Utah Mammoth beat Calgary Flames 3-1, Canucks edge Capitals 4-3

The Utah Mammoth defeated the Calgary Flames 3-1 on Wednesday night in Salt Lake City, and the Vancouver Canucks edged the Washington Capitals 4-3 on Sunday in Washington, in two nationally televised NHL games that highlighted hot starts, goaltender performances and lingering injury concerns.

In Salt Lake City on Oct. 15, the Mammoth got second-period goals from Barrett Hayton and JJ Peterka and a late empty-netter from Kevin Stenlund to seal the victory. Goaltender Karel Vejmelka made 19 saves as Utah improved its early-season home form, becoming the sixth NHL franchise to win each of its first two home openers. Rasmus Andersson opened the scoring for Calgary with a power-play goal in the first period, and Flames rookie Devin Cooley made his season debut in net, stopping 29 shots.

Hayton tied the game 1-1 at 1:16 of the second by snapping a shot into the middle of the net, and Peterka gave Utah its first lead at 4:24 of the period on an unassisted breakaway wrist shot. Utah generated sustained pressure in the middle frame, aided by six Calgary penalties and an 18-3 edge in shots on goal during that period, but the Mammoth went just 1 for 16 on the power play through five games....
