Kevin Durant  scored 23 points and grabbed 11 rebounds while former Boston College  star Reggie Jackson  hit a couple of key baskets off the bench as the Thunder ended the Celtics ‘ five-game winning streak with a 91-79 win Sunday afternoon at Chesapeake Energy Arena.
Paul Pierce  led the Celtics with 20 points while Kevin Garnett  added 10. But Garnett, who hit four of his first eight shots, missed 10 in a row at one point, including his first eight of the second half as Boston fell short in their bid to sweep the Thunder, who improved to 47-16. The biggest difference in the game came at the free throw line, as the Thunder hit 27-of-33 shots while Boston attempted just 20, making 14.
The Celtics (34-28) hung in with No. 2 seed in the West, overcoming a pair of 10-0 runs by the Thunder in the first half to trail by just five points at halftime, 50-45. After shooting 51 percent in the first half, the Celtics went ice cold in the second half, making just 10-of-40 shots in the second half. They finished shooting just 37.7 percent (29-of-77) from the field.
The Celtics turned up the defensive pressure in the third quarter, holding the Thunder to just 18 points and cutting Oklahoma City’s lead to three, 68-65, heading into the fourth quarter.
But the Celtics went ice cold to start the fourth. Oklahoma City opened on a 10-2 run, highlighted by a jumper by Jackson as the shot clock expired. He changed his shot in mid-air and double-pumped to connect.
The Celtics missed 15 of their first 17 shots of the quarter while the Thunder built their biggest lead, 87-73, on a Durant baseline jumper with 3:13 left. But the Celtics responded with six straight points to get the lead down to eight with 2:20 left. After a defensive stop, the Celtics appeared to get the ball back with 1:44 left and a chance to cut the lead even more. But a replay overturned a ball out of bounds off Jason Terry  and the Thunder got the ball back with a new shot clock.
The Celtics forced the Thunder to use all 24 seconds without allowing the Thunder to get a shot off. Jeff Green ‘s 3-point attempted rimmed out with 59 seconds left. The Thunder got the next basket with 37.4 seconds remaining on a layup by Serge Ibaka to put Thunder up, 89-79, and ice the game.
The Celtics are off Monday before taking on the Bobcats in Charlotte on Tuesday night.
