1545: Topics of debate up for discussion? How about will Mickelson take over from Woods as world number one on Sunday for starters? Woods has led the rankings for all but a handful of weeks over the last decade, but Mickelson can take over top spot. Here's what he has to do (deep breath): A second-place finish on his own would be enough if Woods finishes outside the top four. Should Woods make the cut but finish outside the top 18, Mickelson would need to finish no worse than third on his own, and if Woods misses the cut, his fellow American would need to finish no worse than a two-way tie for third to lead the rankings. Got all that? Good.

1540: Right, I've got more than two hours to fill before I get live pictures from California. I need your help to get through this. To get involved use 606, Twitter or text via 81111 (UK) or +44 7786200666 (worldwide) with GOLF before your message. I can't promise to use all messages, but with the current lack of TV coverage, there's a fair chance yours will get aired.

1532: An early excuse for a bit of use of the good news for Europe flag as Finland's Mikko Ilonen birdies his first hole, the 10th, to take a very early share of the lead! Could be a long day for Paul Sheehan though who doubles the first.

1525: I wonder what world number two Phil Mickelson got for his 40th birthday yesterday - bet it wasn't the obligatory umbrella, golf shoe cleaning tools or dozen golf balls that I tend to get. The Masters champion gets his round underway on the 10th at 1606 BST, alongside Ireland's Padraig Harrington. The pair have won seven majors between them, but never the US Open.

1518: Among the early starters are England's Simon Khan, who is in the third group beginning their opening round on the 10th and tees off in about three minutes. Compatriot Luke Donald is in the following group while 2007 US Open champion Angel Cabrera is in the trio after that.

1507:Woods doesn't tee off until just after 2130 BST and has England's number one and world number three Lee Westwood and South Africa's Ernie Els for company over the first two rounds. There's a full list of tee-times here.

1500: Hello all and a warm welcome to what promises to be a superb weekend of golf as the second major of the year gets underway on the Californian coast. Gary Woodland of the United States, South Africa's Deane Pappas and Australia's Paul Sheehan are in the first group to tee off, which they should be doing right about er...now.

1457: The US Open's last visit to Pebble Beach was 10 years ago. Back then Tiger Woods blew the field away. He won by a record 15 shots and was the only player to score under par for the tournament. Easy pickings then for the world number one?
