Polishing my crystal ball

There is a thread on one of the Australia chess forums about Australian players who have played World Champions. David Smerdon did it at the last Chess Olympiad (drawing with Magnus Carlsen), although I believe that future/past World Champions count as well.
Based on his devastating win in the 2018 Grenke Open (8/9), I'm peering into my crystal ball and suggesting that German IM Vincent Keymer may one day be part of that list. And if he is, then this is an early entry for an addition to the OZ v WC list.
