He is resting him up so he will be fresh for the post season, but if the Giants don't win enough games there is no post season. It seams that once every series Posey is resting. That was fine when he could play first while Belt is out, but now that Belt is back its time for him to suit up and play more.
Don't get me wrong I really like Susac and have met him a few times from Cape League games, but he is no Posey and is up too fast. He should have been called up next season not this season.
They should cut Posey's rest days to day games after night games only.
