QR1: (q6) Boris Kozlov (USA) WR 1701 (CH = 1600 in January 2018) vs (qWC) Samuel ??? (*)
(*) No idea who this is, as the link on ITF page comes up as "unforced error", while the printable version of the draw doesn't come up at all! Samuel Beddow perhaps? I don't think it's Toby Samuel, as his current ranking is 470. That said, at N° 130 in the alternates list is a "Samuel Samuel E Nicholson"...
