Kyrie Irving scored 12 of the Celtics’ last 17 points — including three free throws to tie the game with 9.8 seconds left in regulation — as the Wizards lost to the Celtics 110-104 in overtime on Thursday evening.

The game was a back-and-forth affair throughout the first three quarters, as neither team led by more than five points. Boston took control midway through the fourth quarter with a 13-3 run that appeared to make the difference, but Washington came back with an 18-5 run of their own, capped off by an elbow jumper from Otto Porter, to take a three point lead with 27 seconds left.

Irving got a quick layup on the other end to cut it back to one, and then, after a pair of free throws by Porter, Markieff Morris committed a foul on Irving while he was attempting a 3-pointer which allowed Boston to tie the game and force overtime.

Washington got some offense early in overtime from Marcin Gortat, who hit a pair of layups early in the period, but the Wizards wouldn’t make another field goal the rest of the way. The Celtics’ defense forced Bradley Beal into a number of contested jumpers while Irving drew two more fouls on jump shots that helped the Celtics seal the victory.

Takeaways

Otto Porter succeeds against Boston again

Stop us if you’ve heard this one before: Otto Porter had a really efficient night, scoring 27 points on 9-of-18 shooting, but other than his elbow jumper with less than a minute left in regulation and one open jumper he missed in overtime, was not much of a factor in the team’s late-game offense.

On the bright side, it was encouraging to see that he had another strong night against the Celtics after scoring 20 points on 10 shots when they met on Christmas Day. Hopefully Washington will continue to be able to exploit what Porter does well against Boston if they meet up again in a playoff series.

A tale of two Oubres

Kelly Oubre Jr. hit a huge three late in regulation to give the Wizards the lead. It was a good test for the pressure he’ll face come playoff time in a bigger role than what he had last season.

However, he bit on silly pump fakes on multiple occasions and let frustration over calls get the best of him at various points.

Morris’ foul at the end of regulation will get all the attention, but Oubre could have helped them avoid the situation altogether with a more disciplined game tonight. That’s something he’ll need to clean up to keep Brooks’ trust as rotations get tighter in the playoffs.

Game Notes

• Marcin Gortat was the only Wizard who made a field goal in overtime. Apparently “Everybody Eats” doesn’t apply to overtime.
• The Wizards have to be kicking themselves for losing a game to the Celtics in which Al Horford had a very quiet 12 point, 2 assist night.
• John Wall’s outfit on the sidelines was nothing short of incredible. He looked like if will.i.am became a professor for some reason.

• Tim Frazier had some nice moments in the second half to keep the Wizards in the game when it looked like the Celtics’ bench might be primed for a run.
