Buster Posey is expected to make his spring debut with the Giants on Friday. It would mark the catcher's first game since he severely injured his left leg last May 25. San Francisco manager Bruce Bochy says that Posey will likely rest on Saturday and then play four innings Sunday if all goes well. "It's going to be a big day for Buster," Bochy said. "He's been waiting for this day for quite a while. He'll have some anxious moments; he'll be hyped up."
