In the Mariners' win over the Tigers in game two of the ALDS, Detroit ace Tarik Skubal may have made a game-changing mistake.
Skubal threw his changeup only 21.6 percent of the time. He threw his changeup 23 percent of the time against right-handed hitters and 13 percent of the time against left-handed hitters. That's significantly lower than the amount of changeups Skubal was throwing in the regular season.
In the regular season, his changeup accounted for 31.4 percent of the pitches he threw. In fact, he threw it more than any other pitch this season.
