Russell Westbrook was his usual aggressive self on Sunday versus the visiting Boston Celtics. However, Marcus Smart matched his energy and scoring to lead the Cs to a big road win to the tune of 100-85.

Smart had a career-high 26 points on an efficient 9-of-14 shots from the floor to beat the Westbrook-led Thunder still playing without Kevin Durant, who is out due to a hamstring injury. Playing against OKC appears to be a motivation for Smart, who broke his previous career-high of 25 points, also against the Thunder.

Westbrook outscored Smart with his own 27 but missed 15-of-20 field goals overall and making just 2-of-10 shots from behind the arc. The Celtics also got great contributions from starters Isaiah Thomas (20 points and 8 assists), Jae Crowder (10 points) and Jarred Sullinger (8 points and 15 rebounds) plus 14 points off the bench from Avery Bradley.

As a team, Boston shot 47.6 percent from the field (39-of-82 FGs) and outrebounded the Thunder, 47-34. The Thunder shot just 36.4 percent field goals (28-of-77 FGs) including 6-of-25 from behind the arc. Other than Westbrook, who was well defended by the Celtics backcourt, only Serge Ibaka finished in double-figure scoring with 16 points.

After starting the season at 1-3, the Celtics have now won four of their last five games to improve to 5-4 for the season. The Thunder had a three-game winning streak snapped and will still be without Durant in the next week or so.

Boston continues a short road trip matching-up against the Houston Rockets on Monday while Oklahoma City will face the Grizzlies in Memphis the same day.
