Barry Zito warmed up inside as the celebration began without him. When he heard his name, he popped out for a quick look. Then, back to his routine. Zito spent all winter relishing in the World Series win -- and now, he's starting anew. "I'm grateful," he said. "It was such a blessing. We're not taking anything for granted." Zito saved San Francisco's season by beating the Cardinals last fall in the NL Championship Series, then delivered again with a 1-0 victory over St. Louis on Friday as the Giants celebrated their latest World Series title throughout the home opener.
