Heyward does have tremendous upside, but as of now he is only playing in A. Chris Davis is raking the baseball at the AA level and earned a promotion to the Pacific Coast League(AAA). I personally scouted Davis when he came down to Corpus with Frisco, and every time I saw him, he got on base(over the top, but he got on a lot). His best game that I have personally seen, was his two homer game against Corpus. He came up in the top of the 9th and jack his second one to the right field berm. He has tremendous power and, if developed correctly in AAA, has potential to have a .300+ avg. He could be up in the majors very soon, possibly this year if he can perform in AAA as he did in AA. And if the Rangers continue to start Frank Cattalanotto at first, then Davis has the edge over him in all offensive categories and has solid defense.
Jay Bruce is mah franchize. I love you Chris Davis!
