Former Pirate Neil Walker grades the Pirates first half of the season and Seth Hernandez's future

What is Neil Walker's go-to cookout meal? Neil says he is very simple: burgers and dogs. Neil gives the Pirates a B and 82% when grading their first half. The pitching brings the grade down a lot with their poor first half. Is it possible we see Seth Hernandez coming out of the bullpen in September? Neil says it is definitely possible even if the Pirates add bullpen arms at the deadline. Hopefully there is not a revolving door between the minors and MLB arms and the bullpen is steady when it comes down the stretch. Neil suggests having him throw in low leverage situations just to see what he has.
