Argentinian Emiliano Grillo continues to lead the way at the Perth International at Lake Karrinyup, with the 20-year-old holding a three-stroke lead over American Bo van Pelt during the third round.

Grillo remains on his overnight score of 11-under after two holes on Saturday, while world No.10 Jason Dufner eagled the par-five third to move to seven-under.

West Australian Jason Scrivener is also at seven-under, with Andrew Dodt, Robert Coles and Stephen Dartnall one stroke further back.

The big shock of the tournament came on Friday, when 2011 US Masters champion Charl Schwartzel missed the cut by one stroke.
