I've never had a DITR come close to the ML, let alone post a 15 win season. Is he great? Of course not. Maybe his team has a great offense. I don't think he will remain a ML SP for long with those splits, but he has decent control and a 90 #1 pitch. He might hang on as a LRB on a mediocre team for a while, but for this one season he didn't suck.
