The Celtics overcame a slow shooting start to run away with Game 3 in a 104-84 rout over the Miami Heat to take a 2-1 series lead. The victory gives Boston back homecourt advantage in the first round series with a pivotal Game 4 looming on Monday night.

Jaylen Brown (22 points) and Jayson Tatum (22 points, 11 rebounds) led four different Celtics to finish in double figures in the victory as the visitors erupted for 42 points in the second quarter to turn a tight ugly first quarter battle in a comfortable lead for the entire second half.

Kristaps Porzingis bounced back from a Game 2 dud with 18 points and a pair of blocks while Derrick White became a pivotal focal point of Boston’s offensive attack after a quiet Game 2, scoring 16 points while shooting 50 percent from the field.

Boston’s defense was the bigger story in this one as though as the Heat were held to 59 points through three quarters including 12 in the opening frame as Boston’s gameplan and focus were vastly improved after a record-breaking shooting night from 3-point range on Wednesday night.

Boston will look for their fourth consecutive road playoff win in Miami on Monday night in Game 4 on South Beach.

Here are four takeaways from the Celtics’ win on Saturday night.

Kristaps Porzingis bounces back: The seven-footer struggled through one of his worst performances of the year in Game 2 but came out with a renewed purpose Saturday night. The big man had an efficient shooting night with good shot section but also delivered a strong passing eye which helped Boston’s offense find some rhythm in the second quarter. His defense was a huge plus as he overcame early foul trouble to battle hard against Bam Adebayo all night while providing valuable rim protection (two blocks). He was supposed to be a game changer for this Heat matchup and he proved to be just did that in Game 3.

Boston’s effort reaches different level: The Heat invited open 3s for several Heat players in Boston but the tide turned on Saturday night. Extra effort on closeouts happened early and often during Miami’s 12 point first quarter and the defensive communication was far superior all night. That led to a huge reduction in 3-point attempts for the Heat and had Miami reverting back to their subpar offensive habits that we saw throughout the regular season.

Payton Pritchard provides a spark: The reserve guard led the visitors in points off the bench and it was easy to see why. He was a thorn in the side of Miami’s guards as the Celtics built a double-digit lead in the second quarter and also made a host of effort plays on the offensive glass that led to second-chance points for himself and his teammates. After failing to make a meaningful impact in Game 2 (zero shot attempts), Pritchard left his fingerprints all over this win during his first half stint.

Jayson Tatum does it all: The All-Star forward led the visitors in points, rebounds and assists in the victory while turning the ball over zero times. The clean brand of basketball (Boston finished with five turnovers) held the Celtics to overcome a slow shooting start but Tatum’s impact was felt all night as he reasserted himself as the best player in the series with his ability to get to the line, hit the glass and find open teammates. Miami’s physicality did not impact his game and that led to an easy win for Boston.
