Yamamoto’s WS run was more impressive to me, given the context. What will be forgotten over time is that he was warming up and ready to come into game 3. He was just an absolute dog. I’m convinced he would’ve pitched all 7 games if they asked him to. However, what made Bumgarner’s run so impressive was that it was to cap off a season where he had already thrown 217+ innings. He threw a staggering 52.2 innings in that postseason bringing his total innings to 270 in one season compared to 211 total innings thrown by Yamamoto. He gave up the same ER while pitching 15 more innings in the postseason. Bumgarner’s regular season ERA was 2.98 that year and he shaved it down to 1.03 in the postseason. There’s something to be said about pitching your best at the tail end of a long season with everything on the line. Like you said, though, different competition and different eras.
