The crowd was loud, the number of jerseys with his name on the back were plentiful, and Cooper Flagg was back in New England for his first game at TD Garden as an NBA player Friday night.

Flagg, whom the Mavericks selected with the No. 1 overall pick in last year’s draft, grew up in Maine rooting for the Celtics. Boston was as close to a hometown team as he could get back then.

During his postgame press conference, Flagg was asked what the crowd was like and whether or not he’d like to experience it from the other side as a Celtic one day.

“Nah, I love being a Maverick,” Flagg said. “That’s home and I don’t want anything else. It was incredible to be able to play here, obviously this is the place where I came as a kid and got to watch, so I think it’s going to be incredibly fun for the rest of my career for me to be able to come here and playin front of this crowd.”

Flagg, who is in the first year of his rookie deal, likely won’t hit free agency until 2030. Bringing him to Boston before then would probably have to involve a trade. He is under contract for next season, and the Mavericks have a club option for 2028 and 2029.

With Flagg averaging 20.3 points and 6.5 rebounds as a rookie with room for his game to grow, hanging onto him as long as possible seems like the logical move for Dallas unless something unexpected happens.

Despite losing to the Celtics by 20 points during Jayson Tatum’s return, Flagg seemed to enjoy the experience of playing in Boston.

“I had a lot of people come up from back home. Having that experience was really cool,” Flagg said. “The energy was incredible tonight, obviously, with Jayson coming back. The energy was great, it’s an incredible environment and an incredible place to play.”

His time in Texas is just beginning, and this isn’t the Mavericks’ last trip to TD Garden. But, there’s nothing like the first one, and this was a moment that Flagg wanted to savor.

“It meant a lot. I tried to take a moment to take a deep breath and take it all in,” Flagg said. “It’s a dream come true just being out there on that court competing and playing at a high level. It’s really special.”

There was no doubt which of Friday’s 24 MIAA basketball tournament quarterfinals served as the game of the night, as the Shamrocks rode their post prince’s 36 points and 18 rebounds to a 65-60 double-overtime win over No. 6 Bridgewater-Raynham, despite trailing by 7 midway through the fouth quarter.

That was one of two upsets on a night that saw 23 teams punch their semifinal ticket, with another 13 slated for Saturday, alongside five hockey semifinals.

Whitman-Hanson senior Dylan Hurley got her 1,000th point out of the way early so she could focus on beating Oliver Ames in the Division 2 quarterfinals. Hurley entered Friday needing just 2 points to reach the mark, and she did so less than eight minutes into an eventual 51-47 victory.

Hurley, who is committed to Saint Anselm, finished with 17, including the tying bucket with 29 seconds left, plus two key free throws, giving her 17 points on the night and 1,015 for her career, putting her fourth in program history.

All 13 girls’ games went to chalk, but there were a pair of lower seeds winning on the boys’ side. We already covered No. 14 Bishop Feehan taking out No. 6 Bridgewater-Raynham, just two days after the Spartans eliminated No. 3 Needham. Thus far, they are the lowest-seeded team to reach the semifinals in any division across basketball and hockey, with a baker’s dozen basketball quarterfinals still to be played Saturday.

Also pulling off a quarterfinal upset was No. 6 Lynn Classical, which knocked off No. 3 Tewksbury, 68-59, in the Division 3 bracket, led by 29 points from senior DJ Reynolds and elite defense from seniors Shyheim Babb and Deshawn Rucker.

Abby Broderick, Medfield — The sophomore exploded for 31 points and five rebounds as the top-seeded Warriors took care of business against No. 8 Norwood, 66-46.

Grace Higgins, Millis — The senior wasn’t the team’s leading scorer (Ella Maher had 17) but she made her presence known in the paint, blocking eight shots to go with 9 points and nine rebounds.

Jimmy Farrell, Masconomet — The senior captain chipped in everywhere, spreading out his impact with 17 points, 6 rebounds, 3 assists, 2 steals, and 2 blocks in a 61-25 win over Burlington in Division 1.

Brody Bumila, Bishop Fehan — Where to start? The 6-foot-9-inch senior was absolutely dominant in a 65-60 two-overtime upset of Bridgewater-Raynham, scoring 18 of his team’s 22 points in the fourth quarter and overtime to finish with 36 points and 18 rebounds. Committed to play baseball at Texas, Bumila has 117 points and 55 rebounds over three playoff games, which have featured six overtime periods and two Shamrocks wins.

Six observations as we enter the MIAA boys’ and girls’ hockey semifinals Saturday and Sunday. Find the full schedule here.

• The lowest seeds remaining are No. 9 St. Bernard’s in Division 4 boys and No. 9 Medfield in D2 girls. No double-digit seeds made it out of the quarterfinals.
• Only one of the top five seeds made the Division 1 boys’ final foursome, which is a 50-50 split between public (No. 4 Arlington, No. 6 Hingham) and private schools (No. 7 Pope Francis, No. 8 St. John’s).
• The other three boys’ divisions feature 11 public schools and one private: St. Bernard’s, bringing the boys’ total to 13 publics and three privates.
• The final eight girls’ teams include three privates, all in D1 (No. 1 Notre Dame-Hingham, No. 2 St. Mary’s, No. 5 Archbishop Williams) and five publics.
• Of the 24 remaining teams, 18 are public and six are private.
• Of the six divisions, only three No. 1 seeds reached the semifinals, with Catholic Memorial (D1 boys), Stoneham (D4 boys), and Westwood (D2 girls) getting eliminated. Yet five of the six No. 2 seeds are still dancing (the exception, Xaverian in D1 boys)

Milton Academy senior wide receiver Kash Kelly, who hails form Northampton, announced he will play football at Amherst. The 5-foot-11-inch, 180-pounder averaged 21 yards per catch

▪ Southern California sophomore Ellie Thomas, a Needham graduate, was selected as Big 10 Defensive Player of the Week for women’s lacrosse. She went wire-to-wire in the cage, producing a career-high 16 saves, including seven in the fourth quarter, during a 16-14 road win at Arizona State. She also picked up two ground balls.

▪ Northeastern freshman Xavier Abreu, a Phillips Andover graduate from Lynn who was the 2025 A Shot for Life Challenge champion, was named to the All-CAA Rookie Team. Abreu set the Northeastern freshman scoring record, averaging 12.3 points per game and shooting 46 percent from the field.

▪ Brandeis senior Ragini Kannan, a Westford Academy graduate, opened her season with a five-inning no-hitter of Emmanuel for her first career no-no. She struck out four and issued one walk in a 14-0 win in Clermont, Fla.

▪ Brandeis senior Hannah Du, a Winchester graduate, make the All-Northeast Fencing Conference women’s second team for the first time. She led Brandeis with 12 wins at the NFC Meet, and finished the season with 39 victories, good for second on the team.
