Peavy recalled that his family had joined him in Tampa just a few hours before the Boston Red Sox traded him to San Francisco on July 26. Moreover, Peavy couldn't linger, because the Giants wanted him to start against the Dodgers the next day at AT&T Park.
Sensitive to Peavy's concerns, the Giants chartered a private plane to take Peavy, his wife, Katie, their newborn child and two sons to San Francisco.
"It pulled a lot of weight when you think about where you're going to play the next two years," Peavy said.
Peavy's feelings hardened into a conviction as he considered being part of the Giants' third World Series triumph in five years.
"How could you not, as a professional athlete, want to be a part of what we have here now?" he said rhetorically. "I wanted to be in a situation where I felt I could win. Once you've won, it re-energizes you."
Peavy energized the Giants by winning six of his last seven decisions, accelerating their drive to the National League's second Wild Card berth. He was widely renowned as the season's best Trade Deadline acquisition.
"We don't get to the postseason without him," Giants manager Bruce Bochy said of Peavy, 33. "I don't think there was a better move in baseball."
Peavy's performance with the Giants offset his 1-9 record with a 4.72 ERA in 20 starts for Boston. Overall, he finished 7-13 with a 3.73 ERA in 32 starts. "I'm going to show up in Spring Training expecting to do even better than I did," Peavy vowed.
According to the Associated Press, Peavy will receive a $4 million signing bonus, $7 million next season and $13 million in 2016.
Peavy nestled into an opening on the 40-man roster as the Chicago Cubs claimed left-hander Mike Kickham off waivers.
