Parrott reached the last 16 of the Thailand Masters with a 5-3 victory over Hong Kong's Marco Fu, but he was full of praise for his opponent.
"What a player he is," said the Liverpudlian. "I was extremely impressed by what I saw. He's going to be a real handful."
The Benson and Hedges Masters champion, Mark Williams, and Nottingham's Anthony Hamilton became the first two players to secure quarter-final appearances.
Williams scored a somewhat flattering 5-3 victory over Martin Clark while Hamilton reached the last eight of a world ranking tournament for the third time in his last four attempts by beating Fergal O'Brien 5-0. Williams now meets either Stephen Hendry or Tony Drago while Hamilton tackles Nigel Bond or Steve Davis.Reuse content
