Great Britain and Ireland slumped to a heavy 17-9 Walker Cup defeat to the USA as they picked up just 1.5 points from the closing afternoon singles.

Trailing 6.5-5.5 after the first day at Cypress Point, California, the visitors halved the morning foursomes to remain within a point heading into the decisive session.
