The Celtics continued their winning streak despite a weak portion of their schedule, this time beating the Wizards 112-98 on Sunday at Capital One Arena. The C’s improved to 21-5 on the season while the Wizards fell to 3-21.

While it was a close game at the start of the first quarter with 21 points, the Celtics pulled away from the Wizards from then on with a 25:8 run. This allowed the C’s to build a comfortable lead as they were ahead by 15 points at halftime. The Celtics bench was a key part of this run as there was a tight rotation in the first half. Kristaps Porzingis also left the game in the first half due to right heel pain (more on that below).

The C’s came out slow in the second half, including a long scoreless drought. But the Wizards were unable to put pressure on the guests in the meantime. The Celtics played sharper games offensively as they struggled for extended periods of time. But the Wizards never put much pressure on the reigning champions as they never managed to get within single digits in the second half.

Jayson Tatum scored 28 points and 12 rebounds for the Celtics. Payton Pritchard filled the box score with 15 points, 11 rebounds and six assists. Jordan Poole scored 21 points and seven assists for the Wizards; Bilal Coulibaly also added 19 points.

The Celtics will now get another three-day break before facing the Bulls at TD Garden on Thursday at 7:30 p.m. Here are four takeaways from Boston’s win over Washington:

Early exit: Despite playing at relatively full strength on Sunday, the Celtics still had some slight concerns. Porzingis finished the game with 11 points in 11 minutes, but left the game early due to right heel pain. The team initially considered him questionable due to pain in his right heel, although he never returned. The Celtics had a strong lead in the second half, so it may have been a precautionary measure since they didn’t need to rush Porzingis. Regardless, this is something the injury-prone big man should keep an eye on going forward.

From the bank: Pritchard’s unexpected season added another dimension to it all on Sunday. The C’s guard not only scored points everywhere in the penalty area, but also made his 100th 3-point shot this season. Only Timberwolves star Anthony Edwards has made more three-pointers than Pritchard this season. He finished Sunday 5 out of 10 from behind the line. Sam Hauser also had 12 points and seven rebounds off the bench and shot 4 of 9 from behind the arc. Of note, Jaylen Brown (26 minutes) and Jrue Holiday (24 minutes) had a couple of bright nights on Sunday as the backups got things going.

Increase: CS coach Joe Mazzulla used an eight-man rotation in the first half. This was due to the fact that the team played at relatively full strength on Sunday and Al Horford was only missing for rest. After Porzingis left, Luke Kornet enjoyed those extra minutes. Neemias Queta also had 10 minutes in the second half to add depth. Kornet was important on Sunday, averaging 27 minutes, seven points, 11 rebounds and four assists off the bench.

Curiosity in the schedule: If it seems like the Celtics have played in Washington DC many times, that’s right. Sunday was the third time this season that the C’s played the Wizards on the road. The first two games took place on October 24th and November 22nd, both won by Boston. Sunday’s game was added to the schedule after the NBA Cup, so there may sometimes be scheduling irregularities due to the tournament during the season. Luckily for the Wizards, the two teams will not meet again until April 6th in a game at TD Garden to complete the season series. The C’s will get a few more days off since they only played two games in 11 days, so they can continue to rest and practice in the meantime.
