TUCSON, Ariz. (AP) -- Pima County's supervisors have voted 5-0 to allow the Chicago White Sox to end their spring training contract with the county so they can move immediately to the Phoenix suburb of Glendale.

The White Sox will pay the county $5 million to leave.

The American League team's contract had called for staying at Tucson Electric Park through 2012. Instead, the White Sox will share a new facility in Glendale with the Los Angeles Dodgers starting next spring.

Board president Richard Elias called Tuesday "a really sad day for baseball here in Tucson."

The decision makes it likely that the other two major league teams, the Arizona Diamondbacks and Colorado Rockies, also will bolt under clauses allowing them to leave if there are fewer than three teams.
