Things are heating up in Phoenix after the Mercury acquired 5-time All-Star forward Alyssa Thomas in a trade with the Connecticut Sun, per reports.

Thomas was designated as the team’s franchise player earlier this month, meaning the only way she could sign with another team was via trade. The move can't become official until Feb. 1.

The Connecticut Sun traded Thomas to the Phoenix Mercury on Tuesday, according to ESPN’s Alexa Philippou. It’s unclear what the Sun will get in return. Thomas was originally drafted by the New York Liberty in 2014 but was traded on draft day to Connecticut and will leave the team as one of its greatest players in franchise history.
