Phoenix Mercury Among WNBA’s Youngest Teams in 2025

Phoenix is now without two future Hall of Famers, Diana Taurasi and Brittney Griner. Taurasi hung up her sneakers after 20 seasons with the Mercury and Griner joined the Atlanta Dream as a free agent.

It’s safe to say that Phoenix Mercury fans will have a bit of a learning curve to take on this WNBA season, as the league stalwart breaks in a new lineup under second-year head coach Nate Tibbetts.

Even without a single pick in the 2025 WNBA Draft (Phoenix traded away all three of its picks), the Mercury’s average player age of 25.56 years ranks third leaguewide, behind only the Washington Mystics (24.72) and Dallas Wings (24.89). Phoenix is just a bit younger on average than the Minnesota Lynx (25.75) and the WNBA’s latest expansion club, the Golden State Valkyries (26.33).

Among the newcomers in the Valley for fans and Arizona sportsbook apps backers to keep an eye on this year are five-time WNBA all-star power forward Alyssa Thomas, acquired in a February trade that sent Natasha Cloud, Rebecca Allen and Phoenix’s first-round draft pick to the Connecticut Sun. Fellow WNBA veteran center Kalani Brown arrived via a four-team trade from Dallas this offseason after averaging 5.7 points and 3.1 rebounds per game for the Wings in 2024.

Throw in returning starters like guard Kaleah Copper, who averaged 21.1 points and 4.5 rebounds per game in her first season with the Mercury in 2024, and you have a solid rundown of the type of talent that Tibbetts and his staff will lean on this basketball season.

Regardless of Phoenix’s age, it seems like oddsmakers aren’t shy on the Mercury’s bullish future. Phoenix has WNBA title odds of +1500 at DraftKings Sportsbook Arizona, ranking fifth leaguewide, as the franchise prepares for the regular-season opener on May 17 against the Seattle Storm in downtown Phoenix.
