Northampton Saints 27 - 16
Ospreys Scarlets 26 - 26 Racing Metro
The Ospreys were second best to an impressive Saints side this afternoon, going down by 27 points to 16 at Northampton.
Dan Biggar did give the visitors a glimmer of hope with a second half try but the result was never really in doubt.
Meanwhile the Scarlets let a sixteen point lead slip to end with a draw at home to Racing Metro last night.
Rhodri Williams got the home side's second try to send them in 26-10 ahead at half time.
But the Scarlets were grateful for a share of the points in the end after the visitors had a try disallowed in injury time.
