In an article published 17+ years ago, TCB founder rastronomicals, with some help from former contributor Bill Gilbert, used Bill James’ GameScore to sort out the contenders from the pretenders in Houston’s rotation. The big winner in nearly every category that season was Roger Clemens, with an average of 63.5. The club wasn’t always great at backing him up, going 15-17 in games that he started. For context, they were 74-57 in games he didn’t start.
Quality Starts have long been defined to mean any game in which the starting pitcher lasts at least six innings and allows three or fewer runs.
