First of all, if they're going to move in the fences, why wouldn't you bring in left field so poor David Wright, a slugger in the old Shea Stadium, could start going yard again?
Right field? The last time I checked, Lucas Duda, among others, had no issue reaching the Pepsi Porch.
The timing couldn't be worse for this. The Mets' strength is their very strong young pitching both currently on the roster and those that will see the big leagues for the first time in 2015. Moving the fences in to make it more of a hitter-friendly park will sabotage what the front office and farm system have worked so hard to nourish over the last several years.
The Mets could be like the Giants (or Royals) within a couple of years if they trade some of the pitching to get some offense. They should stay on the path of building around their pitching staff and bring some offense in.
Could it be the dimensions of the Citi Field are keeping potential free agents from coming to Queens? Could be. And moving the fences in could entice them to be more open to joining the Mets. But this is a measure that should have been taken care of before the Mets went out and built the formidable pitching staff they will have in '15.
