Metta World Peace swiped the ball from Kevin Durant and hit two free throws with 12.9 seconds left for the third-seeded Lakers, who shook off the memory of their late collapse in Game 2. When Kevin Durant missed a three-pointer, and Andrew Bynum blocked Serge Ibaka's shot at the buzzer, the Lakers' frenzied crowd celebrated their second win in the last six playoff games.
Durant scored 31 points before missing his last shot for Oklahoma City, which could have moved to the brink of its second straight trip to the Western Conference finals.
Game 4 in the back-to-back set is Saturday night.
76ERS 92, CELTICS 83
PHILADELPHIA (AP) — Andre Iguodala snapped a tie with five straight points in the final 90 seconds to help Philadelphia storm back from 15 points down and stun Boston in Game 4 of the Eastern Conference semifinals.
The Sixers tied the series at 2 and guaranteed a return home for one more game.
Iguodala, one of the more maligned athletes in recent Philadelphia history, put the Sixers ahead 85-83 and hit a three-pointer for a five-point lead.
Iguodala scored 16 points, Evan Turner also had 16, and Lou Williams added 15.
Paul Pierce led Boston with 24 points. Kevin Garnett had his first bad outing in an otherwise monster series, finishing with nine points.
Game 5 is Monday night in Boston.
