Two years ago, Tim Lincecum was a holy terror to anyone with a hot microphone in a champagne-soaked clubhouse. He snuck enough four-letter words on the air to make the FCC blush. But Saturday night, as the Giants celebrated another NL West title, Lincecum was nowhere to be found. The Giants sent him home early so he could rest up to start Sunday's day game, manager Bruce Bochy said. Following the clinching victory, the club scratched Lincecum and will replace him with right-hander Yusmeiro Petit against the San Diego Padres.
