Breanna Stewart couldn’t turn down a chance to play in New York and potentially help the Liberty win their first WNBA championship.

The most coveted free agent this offseason, who won the WNBA MVP award in 2018, announced on social media that she was going to New York with a photo of her in a Liberty shirt on Wednesday. Stewart had spent her entire career in Seattle since the Storm drafted her No. 1 overall in 2016. She won two championships with the team in 2018 and 2020.

“I decided to go to New York as I wanted to continue to be great. And I wanted to go to the place where I think I can help this league become better, to raise the standard,” Stewart said in an interview on ESPN. “I feel like why not go to the biggest market in all of sports. I’m excited to go after their first championship.”

The 28-year-old wing has averaged 20.3 points and 8.6 rebounds in her WNBA career. She missed the 2019 season with an Achilles injury.

The move turns the Liberty into an instant championship contender. New York is one of the WNBAs original franchises, but has never won a championship. The Liberty already added 2021 MVP Jonquel Jones and Kayla Thornton through a three-way deal to complement 2020 No. 1 draft pick Sabrina Ionescu.

Wednesday was the first day that free agents could sign with teams. Other moves announced included:

• Brittney Sykes with Washington

• Lexie Brown and Stephanie Talbot with Los Angeles

• Teaira McCowan with Dallas

• Alysha Clark with Las Vegas

Many free agents were waiting for Stewart to make her decision, including Courtney Vandersloot.

Vandersloot announced on social media late Tuesday night that she wasn’t returning to Chicago, where she had spent her entire career. She has led the league in assists six times during her 12-year career and helped the Sky win the 2021 WNBA championship.

CHARTER FLIGHTS: Brittney Griner’s return to the WNBA this summer after being traded in a dramatic prisoner swap in December with Russia has collided with free agency, creating potential travel complications for the league out of safety concerns for her.

If Griner, who is a free agent but has said she’ll return to Phoenix, needs special travel accommodations – such as chartered flights – the league will have to come up with a plan for the 6-foot-9 star. Griner’s safety when traveling will be a top priority for her team and the league.

“We are very cognizant of BG’s unique situation,” WNBA Commissioner Cathy Engelbert told The Associated Press. “We’ve been planning and we’ve been thinking it through with security experts, BG’s side, our side. We’ll find the right time to comment on it when she signs with a team.”

While the Griner situation is unique, other marquee players raised the issue of charter flights, which teams have deemed too costly.

The current collective bargaining agreement requires that all teams fly commercial and doesn’t allow teams to charter flights. Any change in that would have to be approved by both the union and the league.

Engelbert says it would cost the league about $25 million each season for each of its 12 teams to charter flights to every game. That number has increased about $5 million from previous estimates by the commissioner due to the new 40-game WNBA schedule this season, fuel costs and other factors.

The estimated cost per franchise to charter flights would be approximately $2 million. Air travel expenses currently for each team is about $150,000, according to two people familiar with the costs. The people spoke to The Associated Press on the condition of anonymity because they weren’t authorized to publicly address the issue.
