Left field has the 16 foot wall, which Ken Davidoff noted could be bumped down to eight feet if the hitters feel they're getting cheated. This would move the home run mark from clearing the wall to clearing a yellow line they put halfway up the wall.
On the other hand, it looks like the right field wall will cause outfielders some problems. The bullpen wall seems to be made up of a chain link fence. Unless the Mets intend on putting some other wall up, which is unlikely or it would have been done already, it looks like whoever is manning RF in Citi better not be afraid of walls made of metal.Everyone surely remembers Aaron Rowand's ridiculous catch in 2006 at Citizen Banks Park. Going back on a Xavier Nady ball, Rowand made the catch and promptly slammed face first into the chain link fence in center field.
Only a portion of that wall was chain link, as the bottom padded like a normal outfield wall. The wall in Citi looks like an eight-foot chain link fence, top to bottom.
Back to talking about CBP, they have a chain link wall in right, but that wall in 15 feet tall. This one looks as if a player could, and would, be able to make a play into or at the wall, possibly crashing into it in the process.
Good luck, rightfielder of the future. Ryan Church better have a helmet on when (if?) he plays right field next season.
Also, take a look at the blueprints. That is one wacky outfield wall configuration.
