I'm not tryin to sound like a know it all, but he was just very unlucky the first half of the year. He's striking out less ppl on this hot streak, but his hits allowed are spread apart, and people are making more contact but not going through for hits. I think the big thing you can look at is his DL stint. Right before that DL stint was his worst stretch EVER and it's not crazy to assume his injury was causin it. Him going back to presumably great health, and maybe that time off was a new slate for him, and boom this happens.
you could be right. just be interesting to know if he has changed anything more in his approach or if its just pitching to contact.
