Washington Capitals star Alex Ovechkin has become the third NHL player to score 800 career goals. He scored three times at Chicago on Tuesday night. Ovechkin scored on his first two shots, beating Blackhawks goaltender Petr Mrazek 24 seconds into the game before stuffing one home on a power play with 11:46 left in the first period. The 37-year-old winger then completed his 29th career hat trick when he knocked Anthony Mantha’s pass over a sprawled Mrazek 6:34 into the third. The rest of the Capitals jumped off the bench to celebrate after the milestone goal, and hats rained down on the ice from the crowd of 16,181 at the United Center. Fans then chanted “Ovi! Ovi!” — drawing a wave from Ovechkin. Washington beat Chicago 7-3.
