Blind comparisons are always fun.
So let's do one.
Player A is Arizona Diamondbacks pitcher Robbie Ray, a guy who is putting up pretty solid numbers despite a walk rate that's a tad inflated.
Player B is also Robbie Ray, just the 2016 version.
As we can see, in 2015 (Player A) Ray had a pretty solid debut season in his first "full" year in the bigs. What he's doing in 2016, though, puts him up there with the big boys.
How good has the Diamondbacks' lefty been, and what's spearheading his success?
