Shortstop Jimmy Rollins could be headed back to his native Bay Area, agreeing to a minor league contract with the San Francisco Giants that includes an invitation to big league spring training camp. General manager Bobby Evans confirmed the deal Monday. While the Giants' infield is all but set, San Francisco has learned the importance of depth at all of those spots with injuries to third baseman Eduardo Nunez down the stretch and also second baseman Joe Panik the past two seasons.
