I believe the physical would be in Philadelphia.
Also, until Harper is under contract it can't be tampering because he's a free agent. He can say whatever he wants, and Trout could have also tried to recruit him to Anaheim (ha). If they chatted in October that would be different (but still probably not actionable).
Haven't read WaPo stories yet (would you mind using the real links instead of Google search results Atown?) but Boswell called Harper working-class? He was just ripping him last week.
I don't think AF ever suggested Harper wouldn't want to come to Philly because he'd rather go to the clubs in New York, at least. That was Machado. It will be interesting to see if they actually do choose to live in Philly full-time but since they don't even have kids yet the question of where to send them to school won't even come up for years. I would think Vegas will still be home, but it's not a long off-season.
