Well then how can you even point to a cause for that if it's years later? You take pitchers out when they're gassed, not when they've reached some arbitrary and all-encompassing pitchcount. You have to set individual limits for each pitcher, and if Z didn't get a 1-2-3 in the 8th, you pull him on the first hit or walk. 107 is not near his limit. No one's arguing for an arbitrary pitch count. But Baker has left Z in past the point of fatigue several times in the recent past. A few starts ago he had clearly lost his mechanics late in the game, but Baker didn't pull him right away. And, by the way, those who study pitching mostly agree that fatigue itself isn't the source of injury; when a pitcher becomes tired, he alters his mechanics, often leading to injury. In other words, it's not 120 pitches that causes an injury, it's one pitch after the point of fatigue. Anyway, since the Cubs have literally a 1 in 500 chance of making the postseason, why leave starters in any longer than necessary?
