I will say that Zimmerman tends to go deeper in games than Hendricks, which has some value unaccounted for in those numbers. However.... 13 of Zimmerman's 32 starts have been against the bottom 3 offenses in baseball. MIA/ATL/PHI and still his numbers have dipped dramatically from 2014. He has the aforementioned scary arm. He will turn 30 next May. I'd rather stay away.
