Booker's total was also the most points scored in an NBA game since Kobe Bryant's 81-point performance vs. Toronto in 2006.
Here's a look at other records or near-records broken by the second-year pro on Friday night:
-Booker is just the sixth player in NBA history to record a 70-point game. Wilt Chamberlain, Kobe Bryant, David Thompson, David Robinson and Elgin Baylor are the others.
-Booker joins Chamberlain and Thompson as the only NBA players to score at least 70 points in a losing effort.
-It was just the 11th 70-point game in NBA history.
-At 20 years and 145 days old, Booker became the youngest player to score 60 points in a game.
-He's also the third-youngest player in NBA history to record a 50-point game. Only Brandon Jennings and LeBron James accomplished the feat earlier in their lives.
-70 points is the most scored in a game against the Boston Celtics. Elgin Baylor's 64 points in the 1959-60 season was the previous best.
-Booker also recorded the ninth 50-point game of the NBA season, setting a new league record for most 50-point performances in a single season.
-Since Booker has been alive, only Kobe Bryant's 81-pointer was a higher single-game total than Booker's 70.
Booker's stat line for the night: 70 points, 21 of 40 from the field, 24 of 26 from the free-throw line, eight rebounds, six assists, three steals and a block.
