St. Petersburg and Tampa were rivals in the manner of St. Paul and Minneapolis after World War II, although the bridges connecting those Florida cities were considerably longer than ours.
The competition there included the St. Petersburg Times vs. the Tampa Tribune.
The NFL brought true major league sports to the Tampa Bay area with the expansion Buccaneers in 1976. The stadium was located in Tampa.
Jack Lake had considerable influence as the Times publisher. Lake and Jim Healey, chairman of the Pinellas County Sports Authority, started pushing the idea of landing a major league baseball team — and placing it in a new stadium in St. Pete.
The Tampa Bay Baseball Group was formed. Vince Naimoli emerged as the main force among those baseball people.
The first true attempt came in trying to attract the Twins in 1984. Gabe Murphy, a 42% owner of the franchise, made a deal to sell his minority share to the Tampa people. Calvin Griffith wound up selling the club to Carl Pohlad that summer.
Following that, the group had a deal with the White Sox in 1988 to move to St. Pete to play in a new dome stadium under construction, and then in 1992 to buy the Giants from Bob Lurie for $110 million.
At the last minute, the White Sox got their new ballpark and Lurie's sale didn't get approved (as required) by other major league owners.
