In pool it is often said by the commentators that a player/team is "on the hill", or if the match goes to the last rack: a "hill-hill game".
Where were these terms first coined, and by whom?
The term on the hill is used when a player/team is one rack away from winning their match, for example the commentator might say:
... and Joe Public wins the rack to put him on the hill in this race-to-5 match.
The term hill-hill is used when both players/teams are one rack away from winning the match, for example:
... and Team Europe win this rack to square up the scores, and take us to hill-hill.
