The Oakland Athletics are checking out the possibility of building a new stadium on the same site of their current home. The A's announced Friday that architectural consultant 360 Architecture will evaluate design options for a new ballpark which would keep the team in Oakland. Team owner Lew Wolff has been stymied in his efforts to get a new stadium. At one point Wolff tried to get approval to move the A's 30 miles south to Fremont but met resistance by the San Francisco Giants who claim territorial rights.
