Rajon Rondo’s triple-double helped the Celtics take a 2-1 series lead over the Hawks.Rajon Rondo made plenty of history in the Boston Celtics’ 90-84 overtime win over the Atlanta Hawks.

Rondo became the first player in NBA history with at least 17 points, 14 rebounds, 12 assists and four steals in a playoff game, according to the Elias Sports Bureau.

Elias also tells us he’s the first player in NBA history to record a triple-double in a playoff game after missing his team’s previous game.

Rondo triple-doubles equal Celtics wins. In Rondo’s 20 career triple-doubles (13 in the regular season, seven in the playoffs), the Celtics have a 19-1 record. The lone loss came to the Chicago Bulls in the first round in 2009.

Most Triple-Doubles Since 2008-09

Regular Season and Playoffs

Including the regular season and playoffs, nobody has more triple-doubles than Rajon Rondo (20) since the start of the 2008-09 season.

Rondo’s seven career playoff triple-doubles are tied with LeBron James for the second-most among active players, trailing only Jason Kidd’s 11.

Rondo really steps his game up in the playoffs. He notches triple-doubles more than three times as often in the playoffs as he does in the regular season. He’s done so once every 34 games in the regular season, but once every 11 games in the playoffs.

Most Career Playoff Triple-Doubles

NBA History

Per Elias, Rondo’s seven triple-doubles in his first 75 playoff games is tied with Kidd for the fourth-most in NBA history. Only Magic Johnson (18), Wilt Chamberlain (8) and Oscar Robertson (8) had more in their first 75 playoff games.

Only five players in NBA history have more than Rondo's seven career playoff triple-doubles. Magic Johnson (30) is the all-time leader in that category.

Rondo has etched his name in playoff lore by joining an elite list of NBA all-time greats.

OTHER CELTICS NOTES FROM GAME 3

• Paul Pierce was 14-of-14 on free throw attempts. Only three times in the past 20 seasons has a Celtic made all of his free throws with at least 14 attempts, and it was Pierce each of those three times.

• Ray Allen came off the bench for the first time in a playoff game. He had started his first 110 career playoff games.

• The Celtics have won nine of their 10 playoff series against the Hawks, with the Hawks’ only series victory coming in the 1958 NBA Finals while the team was located in St. Louis. According to Elias, Boston’s .900 winning percentage in playoff series against the Hawks is the highest any team has over another in NBA history (minimum six series).
