Ricky Barnes completed a bogey-free round of 65 on Saturday to grab a one-stroke lead midway through the weather-delayed US Open.

Barnes, the 2002 U.S. Amateur champion who posted an opening three-under 67 on Friday, came back Saturday morning to birdie three of the nine holes he had left in his second round for eight-under-par 132 in the rain-marred championship.

Holder Tiger Woods, who shot a four-over 74 in Thursday's rain-suspended opening round at Bethpage Black, began his second round 12 shots back. Woods, who won the 2002 Open at Bethpage, parred his first hole.

Glover, who led by one shot when play was called off on Friday due to failing light, returned to birdie one of his five remaining holes and registered six-under 64 for 133.

Canadian Mike Weir, the 2003 U.S. Masters winner who led the first round after his opening 64, posted 70 for 134.

World number two Phil Mickelson finished a second-round 70 for 139, seven shots behind Barnes.

The other half of the 156-man field, including Woods, followed the earlier wave of players onto the course to begin their second round.

More bad weather is forecast with another heavy rain storm expected to hit Long Island on Saturday afternoon.
