George Horne scored a hat-trick as Scotland ran in nine tries in a 61-0 bonus-point thrashing of Russia on Wednesday to set up a crunch Pool A showdown with host nation Japan for a place in the Rugby World Cup quarter-finals.
Horne scored his first two tries from halfback and added a third from the left wing as Scotland finally got their high-octane running game going in their third match in Japan.
Five-eighth Adam Hastings, son of Scotland great Gavin, also made a significant contribution with the first two tries in four first-half minutes and eight conversions for a personal haul of 26 points.
Neither Horne not Hastings are likely to start in Yokohama on Sunday when the Scots take on Japan almost certainly needing to record a victory and deprive the hosts of a bonus point to progress to the knockout stages.
