It is a far cry from Roland Garros or Wimbledon, but professional tennis will return in Germany on Friday.
The first in a series of planned exhibition events will take place without spectators, line judges, ball kids or handshakes.
It is the first competition between ATP players since professional tennis was suspended because of the coronavirus pandemic on 12 March.
The Tennis-Point exhibition features eight players outside the world's top 100.
Dustin Brown - who beat Rafael Nadal at Wimbledon in 2015 - is in the field, along with the British number nine Jan Choinski.
