PORTLAND — Markieff Morris couldn’t believe the Blazers kept leaving him open. Morris had 28 points, including a career-high six 3-pointers, and the Washington Wizards won their first game of the season with a 125-124 overtime victory over the Portland Trail Blazers on Monday night. “After the second (3-pointer) I was like, ‘Are they really gonna let me shoot the ball?’ I think that’s the most I ever shot,” Morris said.
