The win is an ineffective tool in pitcher evaluation, far outliving its usefulness as pitchers no longer pitch complete games. Focusing on wins as a method of pitcher effectiveness gives a distorted and inaccurate picture:
1. Pitchers can perform well and receive a loss or no decision through lack of run support or poor team defense
2. Pitchers can perform at a subpar level and receive a win if their team has excellent offense
3. Relief pitchers can record just one out and receive credit for a win.
Eliminate the win and develop more effective statistics to measure pitcher performance.
