Riot Sage Post on Twitter

On 8/31 a twitter user called "@riot_sage" who called him or herself " posted a tweet with the following text:
 * "At Rome T, van to S. F. port. She beat them there. I may go into tame chat. Ending nigh."

This was shown by the twitter team to be an anagram for the following message:
 * go/t a me/s/sage/ f/rom e/van/ to/nigh/t/: the re/port/ i/s he/ may/ be at/t/ending the m/at/ch at/ rio t/into

Current theory deciphers this as pointing to Evan's attendance at Rio Tinto Statium for the USA v. El Salvador Soccer game on Sept. 5th. Current speculation on a recent post by another user points to these clues being from the same source.
