“The King in the Fourth” struck again Tuesday night for the Boston Celtics.

Celtics guard Isaiah Thomas scored a career-playoff-high 53 points in Boston’s 129-122 overtime win over the Washington Wizards in Game 2 of their second-round NBA playoff series at TD Garden. Boston now holds a 2-0 series lead.

Thomas hit the 50-point mark in overtime, and he scored 29 points in the fourth quarter and OT combined. The Wizards scored 30 as a team over that same span.

It was quite an amazing performance, one that came on the same day his sister would’ve celebrated her 23rd birthday.

Thomas’ 53 points were only one shy of John Havlicek’s franchise record for the most points in a single playoff game. Ray Allen (51 points) was the last Celtic to score 50-plus in a playoff game, doing it in Round 1 in 2009.
