The Liberty’s big three added another star. 

The Liberty are signing marquee free agent Satou Sabally to a multiyear deal, The Post confirmed Saturday. 

A year and a half ago, Sabally was dancing on her younger sister Nyara’s double-decker bus during the Liberty’s championship parade.

Now, the elder Sabally will join forces with New York’s Sabrina Ionescu, Breanna Stewart and Jonquel Jones to experience her own championship celebration.

The Liberty pursued Sabally last offseason, but she ultimately went to the Phoenix Mercury.

The three-time All-Star and former No. 2 overall pick is coming off a strong season in Phoenix, where she helped lead the team to the WNBA Finals. 

Sabally led the Mercury in scoring with 16.3 points per game and averaged 5.9 rebounds, 2.5 assists and 1.3 steals in 39 regular-season games. 

In 10 playoff games, Sabally averaged 19 points and seven rebounds to help the Mercury take down the Liberty in the first round and the Lynx in the semifinals en route to Phoenix’ first Finals berth since 2021.

Sabally suffered a concussion in Game 3 of that series against the Aces, which caused her to miss the final game. She was ruled out for Unrivaled as she dealt with lingering symptoms, though she has since been cleared to return to basketball activities

The 27-year-old has dealt with injuries in the past, but, when healthy, she has All-WNBA potential. Her presence makes the Liberty’s starting lineup taller, longer and scarier.

Sabally’s signing comes a week after the Liberty waved farewell to her younger sister, whom the Toronto Tempo picked up in the expansion draft.

The move, though, reunites Sabally with her Oregon teammate Sabrina Ionescu, and the two have unfinished business together after the pandemic canceled the 2020 NCAA Tournament.

Sabally was the first major free agent addition for the Liberty since the signing period opened Saturday.

The Liberty were also finalizing a multiyear deal with Jones, sources told The Post. They also signed Spanish forward/center Raquel Carrera to a one-year, $270,000 deal. 

The Liberty aren’t done yet. 

Ionescu and Stewart are both on the record this month saying they plan to return to Brooklyn this season. The Liberty also intend to re-sign Marine Johannes and have the rights to Rebekah Gardner and Betnijah Laney-Hamilton. 

Training camp opens April 19, and the season is scheduled to start May 8.
