Oakland mayor Jean Quan said Friday that the city has a plan to keep the A's and has identified two viable sites for a ballpark.
Quan held a press conference to underscore the city's commitment and said she will send a letter to Major League baseball commissioner Bud Selig outlining the options.
"We think we are the only city that can get this done in the timeframe for Opening Day 2016," the mayor said.

One location is Victory Court -- just west of the Nimitz Freeway near Jack London Square -- and the other is the current Coliseum complex, which Quan said would be renamed "Coliseum City" -- a sports and entertainment complex.
Assistant city administrator Fred Blackwell said it's "not only about sports, but about the revitalization of our city."
Blackwell said that six companies have submitted plans for the Coliseum area in response to the city's formal Request For Proposal.
City Council president Larry Reid said that the city has met with Major League Baseball's committee several times, and they've evaluated both sites.
