Tim Lincecum always has been a rare bird, from his windup to hishair to his demeanor, so who better to agree to that rare baseballcontract that makes everyone a winner? The two-year, $40.5 million deal, which was completed Tuesdaybut will not be official until he passes a physical next week, isexactly what Lincecum said he preferred four months ago, when hetold The Chronicle, "I just don't know how I'm going to feel fiveyears from now, or three years. That's why I kind of like to takethings step by step." This step makes Lincecum the highest-paid Giant ever, by averageannual contract value, a bellwether figure in the industry. Hisaverage of $20.25 million a year bests the $18 million that BarryBonds and Barry Zito averaged with their big contracts.
