One of sabermetrics’ initial endeavors was to weed out useless and outdated statistics. An example of this is pitcher wins and losses. A pitcher’s win/loss record is not a good reflection of their performance and will do very little to predict their future production.
Clay Buchholz is a perfect example of this so far in 2012. With his win tonight his record improved to 4-1. That means he’s good right? Not so much. If the season ended today his 8.31 ERA would be the worst EVER in baseball’s modern era (1900-Present) for a qualifying starting pitcher. I guess he just knows how to win and willed his team to score 13, 7, 11, and 7 runs in his four wins.
