Fortunately there are so many different stats available on fangraphs that it is possible to discern luck from explainable differences.
I think the telling factor is Hutchinson's line drive percentage. This year it is 25.6% versus 18.6 in 2014 - http://www.fangraphs.com/statss.aspx?playerid=10732&position=P . This seems to indicate that he is being hit harder this year than last year.
Here is an interesting article from fangraphs - http://www.fangraphs.com/library/pitching/batted-ball/ . In this article it states that Line drives are death to pitchers, while ground balls are the best for a pitcher. In numerical terms, line drives produce 1.26 runs/out, fly balls produce 0.13 R/O, and ground balls produce only 0.05 R/O.. The article also explains that if a pitcher is allowing more line drives then their BABIP will be higher.
I found this article to be very informative, however, it was also was very contradictive going by the following statement: We know that pitchers do not have complete control, or even much control at all, over what happens to a baseball once it’s put in play, but they do have some control over the type of batted ball they allow. If you allow ten ground balls, you can’t control if zero, three, or nine go for hits, but you did control the fact that none are leaving the park. On the other hand, fly ball pitchers can usually limit the number of hits they allow, but that also makes them more vulnerable to home runs.. There are contradictions within this one paragraph and it contradicts the entire point of the article. What maddens me is how authors want to make profound statements instead of sticking to the facts (example: If you allow ten ground balls, you can’t control if zero, three, or nine go for hits, but you did control the fact that none are leaving the park., which completely contradicts the point that the author was making in regards to line drives being death to a pitcher.
