LAS VEGAS — After Mfiondu Kabengele completed his G League season with the Rio Grande Vipers, he wasn’t sure what would come next. The 27th overall pick of the 2019 NBA Draft called his agent, Alex Saratsis, and asked him to find a team that would give him a legitimate opportunity.

“The first team he said was, ‘Boston really wants you. What do you think?’ ’’ Kabengele said. “I said, ‘Let’s give it a chance.’ ’’

Kabengele, who played a total of 51 games over two seasons with the Clippers and Cavaliers before spending last year in the G League, joined Boston’s Summer League team and was determined to show he belonged. And the 6-foot-9-inch center was rewarded after a strong showing in Las Vegas, agreeing to a two-way contract with the team after the Celtics’ Summer League finale against the Nets on Saturday night.

“I showed them my heart, my energy, my tenacity,’’ Kabengele said. “There are certain things you’ve got to see for yourself and can’t see in the box score. So I feel like the way I set screens, the way I crash the glass, make plays off the ball, rebound, move the ball, stretch the floor, make my free throws, switch 1-5, those kind of versatility things I feel like are really valuable to a team, and I want to show that for Boston.’’

Over five games in Las Vegas, Kabengele averaged 14.8 points, 8.2 rebounds, 2.4 assists, and 2.2 blocks in just 24.5 minutes per contest. He made 58.7 percent of his shots and 40 percent of his 3-pointers. The former Florida State star said he is eager to get to Boston to start training camp with Celtics frontcourt players such as Al Horford, Robert Williams, and Grant Williams.

“The first day when I see Al,’’ Kabengele said, “I’m going to be like, ‘Hey, can I get your number? Let’s do lunch. How do you do what you do? Because you’re really good at it.’ ’’

The Celtics still have three open roster spots, so there is a chance Kabengele could ultimately play his way into a regular NBA deal. For now, though, he’s thrilled to have this chance on a two-way contract.

“I think my main goal is to work on my skill and my craft, and whatever manifests out of that I’ll be happy with,’’ he said. “I don’t want to put a bar on anything. So if Boston likes what I do and I continue to progress, hopefully something happens. And I’m going to keep working on my game.’’

As he left the Thomas & Mack Center flashing a wide smile, he was ready to begin a string of phone calls to family and friends. He said he wanted to buy his mother a cake.

“I’m just too giddy right now,’’ he said.

The Celtics fell to the Nets, 102-95, in their Summer League finale to finish with a 3-2 record.

Juhann Begarin, 2021 second-round pick, had 25 points and seven rebounds to lead the Celtics and rookie point guard J.D. Davison added 17 points, 10 assists, and 6 rebounds. Guard Brodric Thomas, who was on a two-way contract last season, did not play, joining guard Matt Ryan and Sam Hauser, who sat out the last three games.

The Celtics sliced a 9-point fourth-quarter deficit to 80-78 on a Jordan Bone steal and layup midway through the quarter, but the Nets responded with an 8-0 run.

When Tamara Moore was invited to be a guest on “Good Morning America’’ last month, the former WNBA player and current coach of the Mesabi Range men’s basketball team thought she would be part of a panel discussion about the 50th anniversary of Title IX.

Instead, she was being honored for her role as a trailblazer as the first Black woman to lead a men’s college basketball team. Moore spoke to co-hosts Robin Roberts and Michael Strahan about some of the women she admired for opening doors by ascending into the NBA, including Celtics vice president of player development Allison Feaster.

Feaster received a text message from Stonehill Ccoach Trisha Brown, one of her former coaches at Harvard, saying Moore had just mentioned her on national television. The next step was obvious.

“She has immersed herself in the game,’’ Feaster said of Moore. “She’s hustled.’’

Feaster reached out to Celtics president of basketball operations Brad Stevens and coach Ime Udoka, and there was no hesitation about inviting Moore to be an assistant coach on Boston’s Summer League squad. So for the last two weeks, starting with training camp in Boston and moving on to the games in Las Vegas, Moore has had an up-close view of basketball at a higher level.

“It’s been a great opportunity and I’ve learned so much from the Celtics that I feel like I can bring back when I get back to Mesabi,’’ Moore said. “[Celtics Summer League coach] Ben Sullivan has done a really great job of pulling me in and making me feel like a part of the organization, whether that be in drills, doing the scouting reports, or even having me step out and helping with scouts of other teams. I’ve had a lot of opportunity here to learn, and of course being able to work with amazing players has been great.’’

Her players at Mesabi Range, a junior college in Virginia, Minn., have been awestruck. On the team’s text message chain they’ve sent her countless pictures of herself on the bench during the nationally televised summer league games.

Moore is excited to bring home what she learned over these past two weeks. Her challenges in Minnesota are unique. She does not have any assistants and there is little funding. She even purchased the team’s jerseys on her own last year.

She said there is plenty she can pull from this experience alongside the Celtics’ coaching staff, from practice structures to drills, even as just a one-person operation. She hopes to eventually get a full-time opportunity at the professional level.

“I love coaching, period,’’ Moore said. “I don’t care if it’s girls, boys, junior teams, Olympics. Basketball for me is the most amazing part.’’
