I don't even have to "go back" and try again; just reload the page (Ctrl-R, or Cmd-R, depending on your OS) and it pulls the Phils' data. The link is correct.
My uninformed guess would be that, for whatever reason, the server (mlb.com's problem, not ours) isn't parsing the full link the first time - when you're already on their page, it parses correctly, but when you 're coming from outside, it fails - give up part way through parsing the link. Strange. But it's easy enough to deal with; just reload the page.
