Finnegan had a high 4.4 BB/9 against only a 7.6 K/9 in 2016. That's not a great ratio. He also gave up a lot of homers, not surprisingly more at home at Great American Ball Park, which is a homer heaven. But away he walked almost twice as many batters as he did at home (14.7% BB on the road vs 7.9% BB at home.) Really, he didn't pitch well anywhere.
Honestly, if you're in a "keeper" fantasy league or something, I'd sell high on him or just not keep him around. The Reds would probably be smart to not keep him in the rotation long-term, either.
