The Athletics announced on Tuesday a 20-year agreement with the city of Mesa, Ariz., that will bring the club back to the East Valley city for Spring Training starting in 2015. The agreement also includes a pair of five-year team options that could extend Oakland's stay to 30 years. Oakland, which called Mesa its spring home from 1969-78, will once again conduct workouts at Fitch Park and play its Spring Training games at HoHoKam Park, the current home of the Cubs. Chicago will move into the newly constructed Riverview Park stadium starting next year, when HoHoKam Park will be closed to undergo $20 million in renovations. "We are extremely excited about our future spring home and want to thank the city of Mesa for all their hard work and cooperation in making this agreement possible," said A's owner and managing partner Lew Wolff. "With the improvements planned over the next two years, we believe HoHoKam Stadium and surrounding facilities will rival any in Major League Baseball. Our players and coaches, as well as our great fans, will be the beneficiaries. Today we begin a new chapter of our Spring Training history in Arizona."
