Yup. This random thing does not make sense to me either.
His numbers in POs are mediocre. It’s a fact and the sample is pretty fair to me. I would bet that he is one of the pitchers with more IPs in POs in the game. So if his sample is not fair, no one’s is, and POs numbers are meaningless by definition —which they are not.
OTOH He is one of the best in the game in regular season, no doubt.
Geez if Kershaw had been something close to the pitcher he was in regular season, Los Dodgers would have had at very least another ring.
