British number two Dan Evans pushed Spanish great Rafael Nadal in their first meeting before going down in straight sets at the Rogers Cup.
Evans, 29, lost 7-6 (8-6) 6-4 in a second-round match disrupted by rain in Montreal.
Qualifier Evans could not convert two set points before losing the tight opener, Nadal upping his game at the start of the second to take control.
Top seed and champion Nadal faces Radu Albot or Guido Pella in the last 16.
The 18-time Grand Slam winner - playing his first match since losing to Roger Federer in the Wimbledon semi-finals last month - struggled to cope with the Briton's aggressive and accurate approach play in an entertaining first set.
