It took 29 games before Boston Celtics guard Marcus Smart connected on his first dunk of the season, but boy was it sweet.

In the midst of a blowout win against the Houston Rockets at TD Garden on Friday, the Celtics played around a bit and completed a gorgeous backdoor play for the Smart.

With less than five minutes left in regulation, Smart wisely used a screen from Luke Kornet and was off to a running start near the rim. His teammate Payton Prichard rewarded his efforts with a gorgeous alley-oop pass.

The 27-year-old guard took care of the rest, rising above everyone else for this sick finish.

The Athletic's Jay King later confirmed that it was indeed Smart's first dunk of the 2020-21 campaign.

This season hasn't exactly gone Smart's way as injuries and COVID-19 have limited him to just 29 appearances so far. His name was even linked to numerous trade rumors before the deadline.

Now back to 100 percent, the defensive ace is giving his all for the Celtics in a bid to regain some momentum in the second half of the season.

Smart only finished with six points on 3-of-6 shooting in Boston's win, but he did stuff the stat sheet with 10 assists, four rebounds, three steals, and one block.

And of course, he finished with probably the most memorable highlight of the game in the Celtics' 118-102 victory.
