Cape Town - A strong second half performance from Scotland saw them oust the USA 39-16 at Villa Park in the Rugby World Cup on Sunday.
Scotland had gone into the break 13-6 down after a spirited USA display in the opening period, but the bench came to their rescue in what was a much-improved performance in the second half.
The result means that Scotland are the only unbeaten side left in Pool B.
All five of Scotland's tries came in the second period.
They play the Springboks in Newcastle on Saturday.
