James Harden scored 31 points and sank seven 3-pointers while fighting through flu-like symptoms, and the Houston Rockets beat the Thunder, 107-100, Wednesday night in Oklahoma City to pull within 3-2 in their first-round playoff series. Harden made the first seven 3s he tried and Houston led by as many as 16 before fending off a rally that Oklahoma City helped stymie with its own strategy. The Thunder resorted to intentionally fouling Omer Asik — a 54 percent career foul shooter — with 5:33 to play. Asik went 8 for 12 from the line, extending Houston’s lead to 101-92 with 3:53 remaining before Oklahoma City gave up the tactic.
