The most valuable team is the Sacramento River Cats, an affiliate of the Oakland Athletics owned by Art Savage and worth $29.8 million. The River Cats drew more than 700,000 fans last season (an average of 10,000 per game), the most in the minors.
The River Cats play in Raley Field, among the best stadiums in baseball, period. Raley Field is just eight years old, located just beyond California's State Capital. Affluent patrons can been seen sipping Johnnie Walker at the bar, and the stadium has become a hot place for young adults to socialize on Friday and Saturday evenings. The River Cats own the stadium, which pulls in big advertising bucks from the likes of Coca-Cola (nyse: KO - news - people ). Lawn seats can be had for $5, and the team will throw you an 80-person fajita party in the James Hardie Party Deck for $3,800.
