Arizona is home to a large number of professional sports teams across multiple leagues. It’s currently a great time to claim the latest online betting promos available in The Grand Canyon State. 

The Arizona Diamondbacks and Phoenix Mercury are playing their regular season schedules right now. The Copper State’s lone MLB franchise currently sits five games behind in the National League Wild Card race. Meanwhile, the Mercury are second in the WNBA’s Western Conference with a 15-9 overall record. 

The Diamondbacks won the 2023 National League pennant and advanced to the 2023 World Series, falling 4-1 against the Texas Rangers. In 2025, Arizona has a +13 run differential, although they are 5-5 straight up in their last 10 games played. 

The Mercury rank sixth in points per game, averaging 82.9. However, Phoenix allows 80.2 opponent points per game, eighth-most in the WNBA. They are trending up in 2025, assembling a new roster after being eliminated from the 2024 WNBA playoffs.

Arizona’s most popular sports teams are currently in their offseason. The Arizona Cardinals and Phoenix Suns will get underway in September and October, so there’s still time to place bets on both teams in various futures markets. 

Let’s go to the NFL and dive into the Arizona Cardinals’ outlook ahead of their upcoming 2025 schedule. In 2024, the Cardinals finished third in the NFC West with an 8-9 record. Oddsmakers expect a similar outcome in 2025, setting their win total line to 8.5, with -115 odds on over 8.5 total wins. 

Franchise QB Kyler Murray will run it back with second-year wideout Marvin Harrison Jr., who has put on notable size during the offseason. The team’s top-five draft pick in 2024 had an underwhelming rookie season, so it’ll be interesting to see how he develops with Murray in 2025. 

The Cardinals started 6-4 in 2024, before finishing the regular season with a 2-5 record. Major roster transactions this offseason were primarily made on defense under head coach Jonathan Gannon, the Philadelphia Eagles’ former Defensive Coordinator. 

Trading Kevin Durant to the Houston Rockets for Jalen Green and other compensation thrust the Phoenix Suns into headlines earlier this summer. Arizona’s NBA franchise failed to contend for an NBA Championship with Durant. This massive trade signals that the Suns are entering a rebuild in 2025 and beyond.
