Melbourne: Representing the United States for the first time and making his first trip to Australia, Kevin Streelman wasn't over-awed by a tough Royal Melbourne golf course on Thursday.
Streelman birdied five of the first six holes on the back nine before making bogey on two of the final three to share the first-round World Cup lead with Thomas Bjorn of Denmark, both shooting 5-under-par rounds of 66.
K.J. Choi, Martin Laird of Scotland and Stuart Manley of Wales were tied for third with 67s. Australian Jason Day was in sixth place after a 68, two behind.
