The A's Trevor Cahill just became a richer pitcher than the Giants' Tim Lincecum. Baseball's economic world is a surreal one, indeed. Cahill's five-year, $30.5 million deal Monday is a win-win forhim and the A's. It is also a reminder that the Giants haven't locked up their youngstuds to multiyear rewards. "Generally we prefer lengths of contracts that match up withperformance profiles," Giants managing partner Bill Neukomsaid before Monday night's series opener with the Los AngelesDodgers. "There is no strict rule on long-term contracts. Itdepends on the player and circumstances."
