As his last act of 2012, Buster Posey exploded out of his catcher's crouch, sprinted to the mound and hoisted 185-pound reliever Sergio Romo over his shoulder. Apparently, Posey's ankle is going to be OK. After nothing but pain and frustration a year ago, Posey capped his comeback in the dreamiest way possible. The National League MVP candidate crushed a two-run home run during the Giants' 4-3 victory over the Detroit Tigers in Game 4, then celebrated in a clubhouse where it looked as if Hurricane Sandy was blowing champagne. Posey is a World Series champion. Again. The only regular position player back from the 2010 team now has two titles in his first three years. That puts him on a pace that looks positively Jeter-ian, even if Posey laughed at the thought. "I have no idea what Derek Jeter feels like," he said. "I think he's won a few more." Jeter has won five titles. But the early parallels are there, at least in pencil. Jeter, the New York Yankees shortstop, won the Rookie of the Year award and a World Series in his first season, just as Posey did. After missing out his sophomore season, Jeter got a second ring in his third full season -- just as Posey has.
