MELBOURNE, Australia (AP) — 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 lead at the World Cup with Thomas Bjorn at 5-under 66.
K.J. Choi, Martin Laird and Stuart Manley were tied for third at 67, and Jason Day (68) was sixth place, two strokes behind the leaders.
Another American, Matt Kuchar, shot 71 after four bogeys on the back nine.
The Americans and Denmark were tied for the team lead, three strokes ahead of Portugal. Traditionally a team event, an individual stroke-play competition was added to the tournament this year to mirror the format to be used at the 2016 Olympics in Rio de Janeiro.
Only 12 of the 60 players in the no-cut field broke par.
"I made some good birdie putts today and some par saves as well, so pretty happy," Streelman said. "On 18, the wind tricked us a little bit and it floated me on a hair and it came down in the middle of that bunker and plugged pretty deep. I had no shot. It's going to happen out here, you expect it."
Bjorn had a poor start to his day, four-putting the fourth hole.
"I thought, 'Well, this could be a long day,' but I just kind of kept my composure and made some good birdies and kept playing solid," the Dane said. "It is, in my eyes, probably the finest golf course you can ever play."
