"Bristol played quite well, but we always had the edge on them in terms of physicality, even though we also had a very young pack out there," Gatland said. "James Haskell at flanker is still 18, and our second row pair of Martin Purdy and George Skivington are both just 21. Tom Voyce did extremely well for his three tries and I was glad that Will Green had a run-out at prop in the last 20 minutes after being out injured for the last couple of months."
Alistair McKenzie, Mark Van Gisbergen, Tim Payne and John Rudd were the other try scorers. The only blot on Wasps' day was a rib injury to centre Ayoola Erinle, who could now be out for several weeks.
Saracens survived a tricky test at Penzance & Newlyn, winning 30-20 with late tries from Richard Haughton and Ben Russell.
Irish, the 2002 Cup winners, scored four tries in their 35-29 win at Kingsholm.
