Saracens marched to the top of their Heineken Cup pool with a 31-26 victory over the Ospreys in an entertaining clash at Wembley Stadium.
Rhys Gill, Ernst Joubert and Chris Wyles scored the tries and Owen Farrell, the 20-year-old who is in contention for a place in England's RBS 6 Nations squad, kicked 16 points.
The Ospreys kept themselves in touch with a brace of tries from Ashley Beck while Dan Biggar kicked the rest to ensure they left London with the consolation of a losing bonus point.
Saracens head into next weekend's rematch at the Liberty Stadium top of Pool Five with 10 points, three ahead of Biarritz and the Ospreys.
