SCOTTSDALE, Ariz. (AP) Barry Zito scurried from drill to drill on day one with a smile and a pep that showed he's a new man heading into the final year of his contract.

He even seemed to enjoy the simple process of shadow throwing, with only a towel in his hand and no ball, as San Francisco's pitchers and catchers began spring training on a gorgeous, cool day at Scottsdale Stadium.

Zito suddenly has some nice momentum, not to mention the swagger that carried over from his comeback 2012 season.

Manager Bruce Bochy has no doubts Zito will stay on a roll after he delivered two crucial wins during last fall's run to a second championship in three years for the franchise, including the opener of a World Series sweep against the Tigers.
