MELBOURNE, Australia — World Cup or Ryder Cup: Put Ian Poulter into a team event and he never seems to disappoint.

Poulter's approach to less than a foot helped set up one of England's six birdies on the back nine Thursday to give him and Tyrrell Hatton a share of the lead with South Korea and Australia after the first round of fourballs at the World Cup of Golf.

Cameron Smith made a 10-foot birdie putt on the 18th to ensure he and Australia teammate Marc Leishman were in a tie atop the leaderboard with South Korea's Byeong Hun An and Si Woo Kim, all with 10-under 62s at Metropolitan.

On Friday, the format switches to foursomes, or alternate shot, and again for the final round.

"This tournament's won and lost on Friday and Sunday," Poulter said. "Foursomes is the day when you can take yourself out of the tournament pretty quickly. In fourballs you're always going to make birdies and hopefully you don't make any mistakes."

Poulter has picked up 15 career points in Ryder Cup events for Europe over the United States. He had two in Europe's win in Paris in late September — one with Rory McIlroy in foursomes (he also lost with McIlory in foursomes) and a singles victory over Dustin Johnson.

He was happy with the way he and Hatton combined for the fourballs on Thursday.
