Jackson hit six of his first seven shots and was 3 of 3 from 3-point range while scoring 19 in the first half. He surpassed his previous career high of 23 points with 2:57 left in the third quarter, taking a pass from Durant and rising for a one-handed dunk. Jackson, who finished 9 of 12 from the field, said he doesn't feel extra pressure while subbing in the Thunder's starting lineup for Westbrook.
"Pressure bursts pipes or makes diamonds," Jackson said. "I'm cool with it. I put a lot on myself and I expect big things from myself. I'm just happy to have a pretty good game tonight and most importantly come out with another win."
Moments after Jackson's dunk, Ibaka followed with another slam to put Oklahoma City ahead 89-68.
"In that third quarter, they went on that run and we had no answer," Green said. "We came a little bit too attached to our man and let them get easy layups."
Jordan Crawford scored 17 points and Kris Humphries added 14 for the Celtics. Jeremy Lamb scored 13 points and Kendrick Perkins -_playing against his former team -_added a season-high 12 points to go with six rebounds for the Thunder.
