BOSTON — Reggie Jackson had 28 points and eight assists, and Anthony Morrow scored 28 to lift the injury-riddled Oklahoma City Thunder to a 109-94 victory over the Boston Celtics on Wednesday night.

It was the second win in six games for the Thunder, who are missing stars Kevin Durant and Russell Westbrook.

Jackson, a standout at nearby Boston College from 2008-11, posted his big game a night after scoring a career-high 29 in a loss at Milwaukee.

Rajon Rondo just missed his second triple-double of the season with 20 points, 12 assists and nine rebounds. Avery Bradley added 17 points for Boston, which had won its last two.

The Celtics went 9 for 33 from beyond the 3-point line.

Leading by four entering the final quarter, the Thunder — behind Morrow and Jackson — hit eight of their first 10 shots from the floor and opened a 94-81 lead on Morrow’s floater from the right baseline with 6:13 to play.

They kept up their strong shooting, opening a 105-88 advantage on consecutive 3-pointers by Nick Collison and Morrow.

Alternating between zone and man-to-man defense, Oklahoma City seemed to frustrate the Celtics, who fired up a number of long-range jumpers — missing most of them. The Thunder trailed 64-59 midway through the third quarter, but went on a 9-2 run to take their first lead on Steven Adams’ free throw. Jackson, who had 14 points and four assists in the quarter, swished a 3 from deep with 0.3 seconds left, giving Oklahoma City a 76-72 edge.

In a first half filled with poor 3-point shooting, the Celtics owned a 51-42 edge at halftime. Boston missed 14 of 19 from beyond the arc, including at least four airballs. The Thunder went 3 for 10 on their 3-point attempts.
