Cardiff Blues trio Josh Turnbull, Cory Allen and Alex Cuthbert were all among the scorers as Wales warmed up for the first Test against South Africa with a five-try 34-12 victory over Eastern Province Kings on Tuesday night.
Tries from Turnbull and Allen, with two conversions and a penalty from James Hook, gave Wales a 17-0 interval lead.
Hook and Cuthbert added further tries while Siviwe Soyizwapi crossed for the hosts. Gareth Davies scored Wales' fifth try before Simon Kerrod crossed late on for the Kings.
There was also a comeback for Blues hooker Matthew Rees who came on as a second half replacement for Wales.
The Blues quartet will now hope to be involved in the first Test against South Africa in Durban on Saturday.
