Vern Cotter: 'Scotland very happy with second-half performance against USA'

Vern Cotter has said that he is pleased with Scotland's second-half performance during their Rugby World Cup victory against USA.

Scotland came from seven points behind at half time to win 39-16, scoring five second-half tries in the process to secure the bonus point.

"We're very happy to get the win and the bonus point. It was a game that was difficult to construct because it was a physical team in front of us," Cotter told reporters.

"We weren't particularly accurate in the first 40 but the score early in the second half got us back on track and we managed to build through what was a reasonably difficult day of rugby with a win.

"Hats off to the guys, they worked hard, it was a four-day turnaround so you've got to look at how we come out of it because in six days' time there's another game."

Scotland need to gain five points from their final two games against South Africa and Samoa to secure a place in the quarter-finals.
