Actually, according to the numbers in the article, he has a slightly HIGHER walk rate in his wins than in his losses/no-decisions. Strikeout rate is similar too. And he's only allowed 3 HR all year. Hit rate is the only real difference, which obviously leads to more runs and losses. And you will see similar splits for just about any player -- for example, Justin Verlander this year has a 2.82 ERA in his wins and a 6.55 ERA is his losses. Joe Mauer hits a lot better in Twins wins than Twins losses too. It's a pretty meaningless split when viewed in the aggregate. I guess the frequency of wins (or win-quality games) is probably more important, and to Gibson's credit, 4 of his last 5 starts have been wins, with 2 or fewer runs allowed in each win. Not sure what happened with the 5 walks, but his BB/9 rate is still just 2.9.
