I agree. Based on GDP, Miguel Cabrera is the worst hitter in baseball. All the GDP tells you is that the batter puts the ball in play a lot. Mauer has a low K rate and gets out 67% of the time so that means that he puts the ball in play a lot. Over his career, Mauer has 3933AB, 1270H, 475K and 130 GDP. Which means he grounded into a DP 130 times out of the 2188AB where he put the ball in play to record an out. Less than 6% of his non strikeout outs resulted in a DP. What a terrible hitter.
