The Boston Celtics (5 - 4) upset the Oklahoma City Thunder (6 - 4) 100 - 85 on Sunday thanks to a dominant fourth quarter. This was a tightly contested game, until a dreadful fourth quarter from the Thunder. Oklahoma City went 2 - for - 17 in an 11 - point fourth quarter. The Celtics on the other hand, dropped 28 points in the final 12 minutes and ran away with an impressive victory. This was the first time that the Thunder really missed Kevin Durant and they'll need him to come back as soon as possible to help carry the offensive road. The Celtics are quietly one of the hottest teams in the NBA right now, as they have won four of their last five games. They recently got back Marcus Smart from a toe issue and he put in his best performance of the season on Sunday. Smart tallied 26 points, eight rebounds and three assists in the win. They also got another great performance from Jared Sullinger, who has been fantastic since being re - inserted into the starting five. Sullinger snatched 15 rebounds and four steals in the victory, while scoring just eight points. This team has no superstars on its roster, but it's a deep, well - coached team that can be a threat to anyone on any given night. They'll look to keep up this strong form against the Houston Rockets on Monday in the second half of a back - to - back. This was the definition of a fourth quarter collapse, as there appeared to be a lid on the basket in the final 12 minutes for the Thunder. The team greatly missed superstar Kevin Durant who continues to miss games with a hamstring injury. Russell Westbrook continues to carry the load for the Thunder, as he collected 27 points, five assists, four rebounds, three steals and two blocks in the loss. He did shoot only 5 - for - 20 in the loss and it's just too hard for this Duantless Thunder team to win with a struggling Westbrook. Only one player had double - digits aside from Westbrook and that's very hard to overcome against a deep team like the Celtics. Oklahoma City will look to bounce back on Monday against the Grizzlies in Memphis in the second half of a back - to - back.
