His 55-point outburst on 20-of-33 shooting – including an impressive 15-of-16 at the free throw line – comes after games of 43 points and 20 rebounds against the Minnesota Timberwolves on Friday, and 45 points, 22 rebounds against the Chicago Bulls on Wednesday.
In doing so, Antetokounmpo became the first player since Hall-of-Famer Wilt Chamberlain in 1964 to average at least 45 points, 15 rebounds and five assists over a three-game span.
He added 10 rebounds and seven assists against the Wizards, while fellow defensive stalwart Brook Lopez was also terrific. Lopez scored 21 points on 10-of-13 shooting while grabbing 12 rebounds and blocking six shots.
His 2.7 blocks per game is the best figure among those who have qualified for the league leaderboard by playing at least 70 per cent of their team's games, although Memphis Grizzlies forward Jaren Jackson Jr is averaging 3.1 blocks in his 20 appearances.
Meanwhile, Antetokounmpo boosted his scoring average to 32.8, placing him third in the league, and he is also third in rebounding at 11.8 per game.
With the win, the Bucks are now 24-13, which is tied with the Denver Nuggets for the third-best record overall.
Thunder shock the Celtics
The Oklahoma City Thunder produced one of the more unlikely performances of the season as they broke their franchise scoring record with a 150-117 home win against the league-leading Boston Celtics.
Making the feat even more impressive was the fact that the Thunder were without franchise player and the NBA's fifth-leading scorer Shai Gilgeous-Alexander after he was a late withdrawal due to an illness.
OKC were led by Josh Giddey with 25 points (10-of-15 shooting), five rebounds, five assists and two steals as one of five Thunder players to score at least 20.
The 150 points is the second-most the Celtics have ever conceded in a game as Oklahoma City piled on quarters of 34, 40, 48 and 28 in a completely one-sided contest.
Fox delivers game-winner for the Kings
Fox led all scorers with 37 points on 15-of-22 shooting, adding six assists, three rebounds, two blocks and a steal.
He was supported strongly by two-time All-Star Domantas Sabonis, who had 21 points (eight-of-13), 14 rebounds and eight assists to help the Kings into the Western Conference's fifth seed as they seek to break the NBA's longest active playoff drought (2006).
