Why does the site matter? The issue is they don't want to play a team that just had like a dozen guys test positive within that same week. It doesn't matter if it's in Miami, Washington, Medicine Hat (Alberta) or Kandahar.
The optics are impossible for MLB. You can't have a team voting no after half the other squad testing positive and mlb forcing them to play against some scrub taxi squad. The PR outrage would be impossible to handle and for good reason. The league is backed into a corner now.
