After the 2011 season was left in shambles and a key piece of the future of the franchise wavering in the balance, the wait is over for the San Francisco Giants. Buster Posey will reportedly be starting behind the plate on Friday when the Giants take on the Cincinnati Reds.Posey sat out most of last season, after a collision at home plate with Miami Marlins' outfielder Scott Cousins left Posey with a left leg injury that sidelined him from any physical activities until recently. Now, the Giants plan on testing that left leg in Spring Training and see how it reacts.
