Oakland, Calif. - Major League Baseball's Oakland A's said on Tuesday that they will launch a new service next week that allows fans to have their tickets delivered to their cell phones through a text or picture message. The message will include a unique barcode, which will be scanned at the ballpark. The A's were the first professional sports team in the U.S. to test the technology -- developed by Costa Mesa, Calif.-based Tickets.com -- last October, and will be one of three Major League Baseball teams to use it this season.
