SCOTLAND A 20 WALES A 62 By Mark Rowley at Cartha Queens Park RFC, Glasgow.
The visitors took a 6-0 lead through a 13th minute individual Tyrone Mahoney try that Lee Williams converted.
But Scotland struck back straight away through a Richard Knight effort but the conversion was missed.
Lee Williams broke through the centre to score and convert his own try to make it 4-12 on 24 minutes and Mahoney scored his second eight minutes later with Williams once again adding the extras.
Scotland controversially struck back just before the interval to make the score 10-18 with a John Cox try following two passes that both suspiciously looked forward.
Wales dominated the second half as they scored try after try hardly pausing for breath.
Mahoney burst through for his hat-trick on 42 minutes with Lee Williams converting.
Matt Harvey ran 60 metres to score under the posts four minutes later but somehow Williams missed the kick.
Scott Bessant broke through the middle on 51 minutes to make it 10-32.
