Losing is a topic Jake Peavy hates to discuss. A scowl comes over the White Sox pitcher’s face as he diagrams his internalization of a loss. His speech slows, the volume of his voice drops down low and Peavy hesitantly makes a checklist of ways he now accepts losses. If he gets beat “the right way,” a loss is easier to handle. So too is the notion the outcome isn’t always in Peavy’s hands; as long as he’s satisfied with his effort and preparation, he has learned to better cope. But this kinder, gentler Peavy doesn’t fool Adam Dunn. This will be their third season as neighbors in the clubhouse. They have known each other for more than a decade. And the past two seasons have confirmed what Dunn always suspected -- Peavy abhors losing more than most. Poor results have caused Peavy many sleepless nights. But the same competitive drive has fueled a reinvention that has allowed Peavy, 31, to rebound from a pitcher who wondered if he’d ever win again to an All-Star whom the White Sox signed to a two-year, $29-million extension in October. “What probably separates him from everybody else is -- I don’t care if we’re out playing golf, if we’re fishing, hunting, it don’t matter -- he seems to think he’s going to win every single thing,” Dunn said. “We’ll try to pick the top five drivers in (an auto race) and he’s already got the winners. He’s a super-competitive guy.”
