Europe battled through a torrent of insults from a raucous crowd to grab a record seven-point lead over the United States and move to the brink of retaining the Ryder Cup with a dominant display at Bethpage Black on Saturday.
The reigning champions won both the foursomes and four-ball sessions by 3-1 to seize a commanding 11.5-4.5 lead despite an intense atmosphere with over-the-top remarks causing Rory McIlroy to swear at hecklers who disturbed him multiple times while trying to make putts.

The Americans must produce the greatest last-day comeback in Cup history to reclaim the trophy, needing 14.5 points.
