Brett Rumford took a change of format in his stride to complete a dominant week at Lake Karrinyup by winning the inaugural World Super 6 Perth.
Rumford was the standout player across three rounds of strokeplay in Western Australia and led by five strokes on 17 under after 54 holes.
However, the unique format in use at this week's European Tour event meant the 39-year-old had to start from scratch when a 24-player matchplay shootout took place on Sunday, his only advantage a bye through to the last 16 as one of the top eight qualifiers.
After reaching the final with wins over Hideto Tanihara, Wade Ormsby and Adam Bland, Perth native Rumford found himself up against 17-year-old Thai Phachara Khongwatmai - the last man to make the matchplay field after coming through an eight-man play-off for five places 24 hours earlier.
It would surely have been somewhat galling for Rumford had he been beaten by a player that finished nine shots behind him on Saturday.
Yet Khongwatmai's bid to become the second-youngest winner in European Tour history, behind Matteo Manassero, was derailed as his experienced opponent continued to shine.
Rumford, whose quarter-final victory over Ormsby had been completed on a second visit to the custom-made 93-yard shootout hole, won the first in the six-hole final and bounced back from losing the second to a Khongwatmai par by birdieing the fourth and fifth to triumph 2 and 1.
Bland finished third after beating Jason Scrivener in a play-off.
