You may have seen some of comparison’s between Jason Heyward and Mike Trout, both of whom have identical 156 wRC+ marks as of this writing. Heyward is also walking more and striking out less, not to mention playing better defense and running the bases more skillfully than the all-world Angels outfielder. But this isn’t about Heyward looking like Trout, it’s about him looking more like Jason Heyward.
So while it’s perfectly reasonable to be skeptical of the numbers, I don’t believe this is simply a matter of small-sample aberration. Could Heyward’s performance undergo a bit of statistical correction over the remainder of the season?
