66 - for Brett Rumford and Mark Foster after 18 holes at Lake Karrinyup CC.
89 - per cent of Greens in Regulation for Rumford, who also managed seven birdies in his round of six under par.
80 - events since Rumford's last win on the European Tour - the 2013 Volvo China Open.
2003 - Foster is looking for his first victory since the 2003 Dunhill Championship.
69 - Louis Oosthuizen shot a bogey-free round of 69 on his return to Lake Karrinyup. The South African won the Perth International here last year.
17 - Phachara Khongwatmai is just 17 years old, but is only two shots off the lead after the first round in Australia.
11 - eagles in round one, including four on the par five seventh.
7 - holes at Lake Karrinyup go right-to-left, with just two going left-to-right, favouring drawers of the ball. This could be one reason behind the opening 74 of Perth debutant Alex Noren, famously a fader.
1 - This is the first edition of the ISPS HANDA World Super 6 Perth.
