For whatever reason, Fredi doesn't think much of Heyward. He wasn't here to see Heyward's rookie season last year. Fredi likes aggressiveness, so he doubtless doesn't think much of a hitter whose approach is built around patience and taking bad pitches. He said in an interview earlier this year -- said it proudly, actually -- that he didn't really know what an OBP is and doesn't know what his players' OBPs are, so there's not really any chance that he knows Heyward's been getting on base a lot lately, nor that he's been one of the team's best hitters doing this disastrous stretch. He's just going by his gut, as always, and his gut just doesn't trust Heyward.
Frank Wren needs to have sit down with Gonzalez after the season and get on the same page about Heyward. He's still the Braves' most valuable asset. Gonzalez either needs to be told to use him or Heyward needs to be traded while his value is still high.
