Adam Wainwright was preparing to hit a drive Monday afternoon when he paused to scan a text message from his brother, Trey. The text was rather matter of fact: The San Francisco Giants had just signed righthanded starting pitcher Matt Cain, owner of a 69-73 career record, to a six-year, $127 million extension. The deal represents the most lucrative ever awarded a righthanded start pitcher. "It was going to be a good day of golf," Wainwright recalled. Still two years shy of his first bite at free agency Wainwright stands as one of the most obvious beneficiaries of a staggering deal that could influence his value much the way Ryan Howard's five-year, $125 million extension created a floor for Albert Pujols' abortive negotiations with the club.
