Just played some dude in BR who chose Polo Grounds with a bunch of speed/high contact guys like Dee Gordon, Lou Brock and so on and he did nothing but swing for contact. And guess what, I lost so it worked! I hammered a few balls to straight CF which would've been 430+ bombs in any other park, but now they were just routine flyouts.
So if you ever struggle and feel like you absolutely suck at this game, go with speed and contact and play at Polo.
