Boston Celtics guard Marcus Smart etched himself into the franchise's history books on Saturday, setting a new record for most three-pointers made in a single game. The 25-year-old guard knocked in 10 three-pointers in the Celtics' 119-123 defeat at the hands of the Phoenix Suns at TD Garden on Saturday.

Marcus Smart delivered with a team-high 37 points, five rebounds, eight assists, and four steals in 33 minutes. He made 13 of his 25 attempts from the field (52 percent) and went ballistic from deep, going 11-for-22 (50 percent).

The Celtics have been home to some of the best shooters of all time, including Ray Allen who holds the record for most career three-pointers made at 2,973.

Smart shattered the record previously set by now Washington Wizards guard Isaiah Thomas and retired Antoine Walker, who each had nine three-pointers in one game.

Known primarily as a lockdown defender, the 6-foot-3 Oklahoma State product has made significant strides to improve his accuracy from downtown. In 31 games this season, Smart has normed averages of 11.7 points, 3.2 rebounds, 4.6 assists, and 1.5 steals in 31.4 minutes per contest. He is draining 37 percent of his shots from the field and shoots a 33.9 percent clip from past the arc.

After a blistering start to the season, the Celtics have hit a rough spot as of late, losing their last three games against the Detroit Pistons, Milwaukee Bucks, and the Phoenix Suns. The Celtics (27-14) are now tied for third and 4th place in the East with the defending champions Toronto Raptors.

Marcus Smart, meanwhile, continues to be head coach Brad Stevens' X-factor due to his ability to impact the game on both ends of the floor. His offense is slowly catching up to his defensive prowess, which could only mean greater things for the C's moving forward.
