The Liberty reeled off seven straight wins to tip off WNBA season No. 1 back in 1997. No version of this team had matched that sprint from the gate — until now.

This impressive version matched it with the biggest blowout victory in Liberty history, winning by 48 and tying their own single-game, regular-season league record for three-point makes with 19 along the way.

The defending champs went up by as many as 57 and ended up flattening the Connecticut Sun Sunday, 100-52, at Barclays Center.

So they stand at 7-0 in season No. 29.

“I say it all the time: The only team that can beat us is us,” coach Sandy Brondello said before the game. “That’s how much I believe in this team. But that doesn’t mean it’s going to easy. We have to embrace hard and find joy in doing that.”

This one turned out to be easy.

The Liberty shot 62.3% from the floor, including 59.4% on threes. Their 19 makes from beyond the arc equaled the record they set at Chicago on May 22. Ten different players knocked down at least one three this time.

This unselfish team shared the ball for 29 assists overall on their 33 made field goals.

Of course, the end will tell a more important story than the beginning.

“Yes, we’ve had a good start to the season, but we haven’t played anywhere near our potential, and that’s exciting,” Brondello had said. “We’ve had to weather some storms. We’ve had two close games. That’s great. The only way you can get better is by the experience and executing down the stretch.”

Sabrina Ionescu executed on her three-point touch again, hitting four and moving one behind Crystal Robinson’s all-time franchise record of 400. Ionescu scored 18. Jonquel Jones had 13 points and 11 rebounds. That made the Liberty 27-0 when she has had a regular-season double-double.

So they got off to good start in Commissioner’s Cup competition. The two teams with the best record in the East and West over five conference games spread from June 1-17 will meet for the championship on July 1. The Liberty fell to Minnesota in the title round last year.

“We want to definitely go back to the final again, so every game matters,” Brondello said.

Connecticut, on the other hand, is rebuilding. This loss dropped the Sun to 1-6.

“We have a lot of new pieces, new staff, everything,” said Bria Hartley, the point guard from North Babylon, who’s finally back in the league after suffering her second ACL tear in 2022. “I’ve been on teams where it’s been kind of a lot of young players and adjusting. So we need a little more of a learning curve. And the biggest thing is being able to stay together.”

Jones sank two of her first three tries from beyond the arc. The second one made it 13-4.

Timeout, Connecticut.

The Liberty were just sizzling from beyond the arc, nailing seven of their first nine, with Ionescu and Leonie Fiebich making two to go with the pair from Jones.

Breanna Stewart banked one in from straightaway, Ionescu followed with her second and Stewart followed with a fast-break layup, and it was 31-13 after one.

The reserves got into the act more in the second quarter. Jaylyn Sherrod began it with a three. When Isabelle Harrison made a short jumper, it was 40-15 Liberty.

Timeout, Connecticut.

Nothing was going to help the Sun much on this day.

The Liberty sat on a 32-point cushion at the intermission, leading 60-28.

When Ionescu hit a floater, the Liberty had a 14-0 run to start the third and were up 46 at 74-28.

Timeout, Connecticut.

It turned into a 20-0 run. The margin reached 55 in that quarter. The lead sat at 90-36 after three. The spread hit 57 early in the fourth.

“The Liberty’s a big mountain,” Sun coach Rachid Meziane said. “The threats come from everywhere.”

Backup center Nyara Sabally (knee) missed her fifth straight game for the Liberty. “She’s making progress, but she’s still not 100% confident to go,” Brondello said. “. . . It’s a mental component as well. We know Nyara has had some knee issues. But she’s working hard. It’s getting better. But we don’t want it to just be getting better. We want her to feel confident to go out there and play her normal game.”
