England's Les Gillett also advanced on home soil as he saw off compatriot Simon Skelton 2-0.
Gillett won the open pairs title last year and defeated Skelton, a men's fours gold medallist in lawn bowls at the 2002 Commonwealth Games in Manchester, 11-3, 8-7.
Robert Paxton, another Englishman who won mixed pairs and men's pairs gold in 2015, went the distance against Daniel Salmon of Wales.
Paxton eventually defeated the qualifier 9-5, 6-7, 2-1.
The mixed pairs quarter finals will be played tomorrow.
