Wins 1. The only stat that matters. The only way to pick a Cy Young winner. The thing Billy Beane can't get in the playoffs, no matter how many fancy computers he hires to play baseball for him. 2. A simply awful pitching statistic that should be swallowed up by the earth itself, personified, given ears, and forced to listen to a tape loop of Bermanisms for all of eternity. The reason being – and again, you know this, intuitively, even if you have never quite expressed it to yourself – if Carl Pavano gives up nineteen runs in five innings but the Yankees score 20 runs, and they hold on to win, and Pavano gets the win, is Pavano a good pitcher? No he is not. (This scenario is assuming he ever comes back and actually pitches, btw.) If Francisco Liriano throws 9 innings of no-hit ball, but gives up a run on four consecutive errors by Terry Tiffey and gets a loss, is Francisco Liriano a bad pitcher? No he is not. Wins stink to high heaven as a way to value pitchers because they are in very large part dependent on the actions of the other guys on the team.
Of course, according to Joe Morgan, "Wins and losses are how you measure pitchers" (Baseball For Dummies, p. 289).
