Over the last 3 years, in the regular season he’s 53 and 19 with an ERA of 2.14. In the postseason he’s 1 and 5 with an ERA of 4.68. In the last 5 starts in the playoffs, he’s 0 and 5 with an ERA of 6.39.
I seriously doubt there’s any other pitcher in 100 years of playoff history who has lost 5 starts in a row. Anyone who thinks this is just bad luck is a fool.
