All season, Celtics coach Joe Mazzulla has preached about the importance of being capable of winning in different ways. One of those moments arrived Wednesday, when superstar forward Jayson Tatum was ruled out of Game 2 of this opening-round series against the Magic due to a bruised right wrist.

But the Celtics know they are deep and talented and had little trouble securing a 109-100 win that gave them a 2-0 series lead. Game 3 will be played in Orlando on Friday night.

Jaylen Brown had 36 points and 10 rebounds to lead Boston, and Kristaps Porzingis, who suffered a gruesome gash on his forehead late in the third quarter, had 20 points and 10 rebounds. Boston held a 46-34 rebounding edge.

Paolo Banchero had 32 points, 9 rebounds, and 7 assists for the Magic, who made just 15 of 24 free throws.

The Magic trailed by as many as 15 points but pulled within 96-89 with four minutes left. Then Brown responded with a running layup and a high-arcing 16-footer. With 2:39 remaining and the shot clock about to expire, Payton Pritchard whirled and converted a layup over Magic big man Wendell Carter Jr. as he was fouled, pushing the advantage back to 102-91.

Observations from the game:

⋅ There are times when Tatum is out and Brown feels a responsibility to fire up a lot more shots to make up for the absence of scoring. Brown filled up the box score on Wednesday, but he was remarkably efficient.

He started the third quarter with back-to-back 3-pointers to spark an 11-0 run that stretched the lead back to 61-49.

Then later in the period he had a dominant stretch closer to the basket. Over a 60-second stretch he scored inside, came up with a steal and a dunk, and carved through the lane for a finger-roll layup.

Brown finished with 36 points on 19 shots and added 10 rebounds and five assists.

⋅ With 8:19 left in the opening quarter, Kentavious Caldwell-Pope fouled Al Horford inside and boos rained down. Caldwell-Pope, of course, committed the foul against Tatum in the fourth quarter of Game 1 that caused him to crash to the floor and bruise his right wrist. Tatum went up for a dunk and Caldwell-Pope pulled his arm, resulting in a flagrant-1 call.

Then with 4:42 left in the second quarter, Caldwell-Pope and Al Horford got tangled up running upcourt and Caldwell-Pope was called for a foul. Horford had some words for Caldwell-Pope after he fouled Tatum in Game 1, and expanded on his frustrations between games. Horford leapt to his feet to make it clear he was not pleased, and Brown rushed over to Caldwell-Pope and added to that sentiment. If not for the developing situation involving Horford and Caldwell-Pope, nothing about this play would have raised an eyebrow, however. It was reviewed for a flagrant and rightfully called a common foul.

Caldwell-Pope, for what it’s worth, had just 3 points on 1 of 9 shooting, including 0-for-6 from 3-point range.

⋅ The Celtics made a concerted effort to get Porzingis involved in the opening half following his quiet Game 1. He started 0 for 4 from beyond the arc and Orlando did a good job denying his post-up chances early, but Porzingis eventually found space inside against much smaller Magic defenders.

He took 12 first-half free throws, and five minutes into the second quarter backed down the 6-foot-7-inch Anthony Black and converted a basket off the glass to cap a 9-0 Celtics run that gave them a 37-26 lead, their largest to that point.

⋅ The Magic called their second timeout of the quarter following that Porzingis basket. They returned to the court and answered with a 7-0 burst that transpired in just 65 seconds and lingered for the rest of the half before going to the break trailing, 50-47.

⋅ Boston averaged a league-low 19.1 free throws per game during the regular season but topped that mark by taking 23 in the first half Wednesday. That’s how the Celtics went to the break with a 50-47 lead despite shooting just 14 of 39 from the field and 4 of 17 from the 3-point line.

⋅ The Celtics mixed on a zone defense on several first-half possessions. The Magic missed some open looks against it, but they are also not a good 3-point shooting team. The Celtics were whistled for one defensive 3 seconds technical while in zone, however.

⋅ In the final minute of the third quarter Porzingis took an elbow to the forehead from Magic backup big man Goga Bitadze, causing blood to gush. He went to the locker room to a loud roar, and returned moments later to attempt the flagrant foul free throws — with a big bandage on the front of his head and blood on the back — to an even louder one. Porzingis needed to take the free throws in order to be eligible to stay in the game, but he checked out afterward and was not on the floor to start the fourth quarter.

⋅ Despite Tatum’s absence, coach Joe Mazzulla didn’t extend his rotation. He stuck with only Pritchard, Sam Hauser, and Luke Kornet off the bench.
