Meanwhile, MLB Commissioner Bud Selig said in a statement, "I commend the Oakland Athletics and the JPA for their efforts in reaching an extension for a lease at O.Co Coliseum. The agreement on this extension is a crucial first step toward keeping Major League Baseball in Oakland."
Selig appointed a three-man committee more than five years ago to analyze the club's stadium options, and a proposed site near Oakland's Jack London Square neighborhood has proved to not be a viable option, despite conflicting reports suggesting otherwise.
"I continue to believe that the Athletics need a new facility and am fully supportive of the club's view that the best site in Oakland is the Coliseum site," Selig said in Tuesday's statement. "Contrary to what some have suggested, the committee that has studied the issue did not determine that the Howard Terminal site was the best location for a new facility in Oakland."
It has long been owner Lew Wolff's desire to relocate to San Jose, but that's the San Francisco Giants' territory, and Selig has not ruled on whether the A's would be permitted to move there.
The Coliseum, where the A's have played since 1968, is the only stadium in the country that doubles as home to an MLB team and NFL team, and it has endured multiple issues in recent years, notably sewage problems.
The Oakland Raiders reportedly want out of the Coliseum, which is why the A's deal with the Coliseum Authority is expected to include out clauses for both sides.
