When he got demoted he had the most WAR of any starter (still ended up 3rd in WAR as a starter even though he only had 16 starts), best FIP (didn't change), best K/9 (didn't change), 2nd best BB/9 (didn't change), best LOB% (didn't change) and to your point, yeah, crazy bad luck on balls in play. Team worse .344 BABIP.
