The Liberty went on to vanquish Connecticut in four games and nearly forced a fifth and decisive contest against reigning back-to-back champion Las Vegas in October before suffering a 70-69 defeat in front of a near-sellout crowd on the corner of Atlantic and Flatbush.

Now, the quest officially starts again to bring home this franchise’s first-ever WNBA Finals after New York earned a berth in the championship round for the first time since 2002 a season ago.

Armed with arguably the best starting five in the world, reigning WNBA Most Valuable Player Breanna Stewart, former MVP Jonquel Jones, last year’s assists leader Courtney Vandersloot, All-Star guard Sabrina Ionescu and former All-Star Betnijah Laney-Hamilton. the Liberty are locked and loaded.

They ended the preseason with last Thursday night’s 82-79 win over the Sun at Connecticut’s Mohegan Sun Arena.

Ionescu scored 15 points on 6-of-9 shooting, including a pair of 3-pointers, and Laney-Hamilton went perfect from beyond the arc by drilling all four of her long-range shots en route to 14 points.

The victory came two days after a preseason-opening 101-53 loss in Chicago that saw the Liberty’s “Fab Five” combine for only 25 points on 10-of-33 shooting before coach Sandy Brondello sent in the reserves.

“Just our response and being able to come together and put that last game behind us,” said Ionescu after burning the Sun with six rebounds and two steals as well as her strong shooting performance.

“Our response really showed how we came together and trust each other. … We have to take it up a notch (in Washington Tuesday),” she added.

Six-foot guard Marquesha Davis, New York’s first-round pick in this year’s draft, scored eight points on 4-of-6 shooting in only 11 minutes vs. Connecticut, and earned a spot on the roster out of training camp.

Second-round pick Esmery Martinez was waived last weekend, and rookie Jaylyn Sherrod didn’t make the opening-night roster either.

Sherrod did impress her coach with a key steal late in the game while also scoring eight points in 14 minutes. She may appear in a Liberty uniform at some point this year.

“She did a great job,” Brondello said of Sherrod. “She played so hard, but I decided to get her in at the end because she’s a game-changer. … She got a really big turnover at the end to help us win the game.”

Free agents Kennedy Burke, Ivana Dojkic and Leonie Fiebich made the cut for the opener, as did back-up forward Kayla Thornton and center Nyara Sabally.

Though they will likely live and die with their starting five on most nights, the Liberty know the importance of a deep roster, especially as they begin a grueling 40-game season.

“It takes 11, 12 players, however many we have to have a successful team,” Brondello noted. “That’s the great leadership that we have. We’re going to need that all year long.”

The Mystics dropped both of their exhibition contests, including last Wednesday’s 83-77 defeat to visiting Minnesota.

Ariel Atkins poured in 20 points and Myisha Hines-Allen added 12 off the bench for Washington, which beat New York at home 80-64 in last year’s season opener for both squads.

The Liberty rebounded to take the next two meetings, including an 89-88 overtime thriller at Barclays on June 25 that featured a clutch three-point play by Stewart and 31 points from Ionescu.

The Mystics did rebound to take the regular-season finale, 90-88, on Sept. 10 in Brooklyn behind Brittney Sykes’ buzzer-beating shot.

But New York never had to leave home en route to sweeping Washington out of the playoffs just over a week later.

Laney-Hamilton didn’t spend much time dwelling on either of the Liberty’s preseason performances, knowing the regular season was at hand.

“I think there’s always going to be a short turnaround,” she said. “So you can’t dwell too much on the past. We put emphasis on this game because we knew it was our last one before the season starts.”

Tip-off in D.C. is scheduled for 7 p.m. Tuesday and the game will be televised locally by My9.

GIVE ME LIBERTY: The Liberty extended their affiliation with the Hospital for Special Surgery Monday, announcing a five-year partnership with their official hospital. New York has been affiliated with HSS for nearly two decades and the hospital and Liberty revealed that they would increase team physician headcount to more than ever before. “At the core of the partnership renewal is the New York Liberty’s commitment to providing our athletes with access to world class medical care,” said Liberty general manager and 2023 WNBA Executive of the Year Jonathan Kolb. “Continuing to have HSS’ talented physicians in-house is an invaluable resource for our organization.
