2130: Australian John Senden and American David Toms are the big movers from the afternoon starters as they climb to two under after seven and six holes respectively. By the way, Davis Love III always looks like he's going to topple forward as he walks.
2126: Phil Mickelson bogeys the 5th and saves par with a 10ish footer at the 6th as he scraps to stay in touch.
2120: England's Oliver Wilson makes a little step in the right direction after beginning with a double bogey at the 10th. After a birdie at the 11th and a bogey at 15, he birdies 16 and 18 and is level at the turn.
2115: The afternoon starters are struggling to make inroads into the lead of Tiger Woods, with American John Merrick the best at one under after 10. Spain's Fernando Gonzalez-Castano and Fiji's Vijay Singh are also in a group one under out on the course after nine and seven holes respectively.
2106: Colin Montgomerie is staging a little recovery and picks up shots at the 14th and 16th to climb back to one over in his front nine.
2100: Here's some thoughts from Padraig Harrington on being paired with Tiger Woods again: "The great thing when you play with Tiger is that you know you're going to have to play the shots. It puts you under more pressure and you feel like you might as well go after it rather than hang back. It actually helps you focus and you know you have to be on your very best form. It motivates you to play well."
2045: A quick round-up of some notable early strugglers - Oliver Wilson is one over after seven, Ian Poulter is one over after four, as is US Open champ Lucas Glover, Luke Donald is one over after two, Chris Wood ended two over, Darren Clarke and Colin Montgomerie are two over, Masters winner Angel Cabrera is club-throwing at two over after four, John Daly is three over after six and Open champion Stewart Cink is three over after four.
2037: Phil Mickelson begins to warm up by holing a six-foot birdie putt on the 4th to edge to one under.
2030: Let's have a little update on the leaderboard shall we:-5 T Woods -4 P Harrington -3 R Allenby, M Goggin, H Mahan, A Quiros -2 P Goydos, T Jaidee, G McDowell, L Westwood, M Bradley.
2026: Just heard a very downbeat Sergio Garcia interviewed after his first-round one-under 71. Said he putted OK, which is normally his Achilles heel, but reckons he has no confidence over the ball with the rest of his bag. Cheer up, Serge. Early days.
2023: Bad news for fans of a couple of popular young fellas - John Daly and Colin Montgomerie are three over after four holes. Oops.
2018: From JeremyFitch on 606: "Far be it for me to accuse you of stealing someone's idea (see 2000) but I heard a US commentator talk out the exact same 2010 Jack Nicklaus/St Andrews scenario about 20 minutes ago!" Not guilty, Sir! I've just legged it to get some food - I wasn't going to tell you - so I haven't heard anyone else say that. It came to me in the BBC canteen, as most of the world's great ideas have over the years.
2015: The afternoon pairings are going out and Phil Mickelson is the headline act, beginning with two straight pars.
2000: The great man has spoken after his round: "I hit the ball well pretty much all day. I didn't make many putts. If I had it could have been a really low number. I'm very comfortable with how I'm playing. The way the course is set up, you can be aggressive, make a few more birdies going at the flags." That's Woods, in case you didn't guess. Now, how about this. He wins here to get to 15 majors, and then wins the Masters and US Open next year. That means he'd go to St Andrews with a chance of equalling Jack's record, on the very course that the Golden Bear retired in 2005. It's written in the stars, I'm telling you!
1955: Justin, Justin, what have you done? The Rose-meister fights back from three over after 10 to two under after 16, only to drop three shots in the last two holes to end one over.
1940: Padraig Harrington cards 68 for four under, while Tiger Woods sees his final 12ft-er slide left to finish with a bogey-free 67 for the clubhouse lead at five under. From SuperGunner07 on 606: "Another TW, Paddy duel bubbling, hopefully no ignorant ref this time."
1932: Lee Westwood birdies the 5th and 7th and is now two under with two to play.
1923: Tiger Woods misses from 10ft and has to settle for a par at the par-three 8th to stay five under. Padraig Harrington makes par to stay four under. Hunter Mahan drops a shot on the final hole to slip back to three under. Graeme McDowell ends with a two-under 70, while Sergio Garcia cards 71.
1910: Now, would it surprise anyone if I said Tiger Woods was leading on his own? He is you know. A birdie at the 7th, his 16th, takes him to five under.Leaderboard: 5 T Woods (16) -4 H Mahan (17), P Harrington (16) -3 R Allenby, M Goggin (17), S Hansen (14)
1908: Hazeltine is the longest major course ever at 7,674 yards, but check this out - Tiger Woods hit his second shot on 15 - at 642 yards, the longest hole on the course - over the green and into a bunker. Officials have sought to reduce the length a touch, though, moving the tee up 30 yards at the par-three 13th to reduce it to 218 yards, and shortened the 518-yard par-four 12th to 501 yards. But
they have pushed tees back at the other par threes, the 4th, 8th and 17th to leave the aggregate reduction at just 26 yards.
1905: Lee Westwood edges back to one under with a birdie at the 448-yard par-four 5th, his 14th. Fellow Englishman Ross Fisher ends one over after a 73.
1858: I mentioned him earlier and I'm going to do it again. Justin Rose is hot at Hazeltine. He was three over after 10, birdied his 11th (the 2nd) to get back to two over, and has now had four straight birdies from the 4th to get to two under.
1850: Three-way lead time and it's the Tiger and Paddy show once again. They're both four under after 15, alongside feisty American Hunter Mahan (after 16). Robert Allenby, Soren Hansen and Michael Bradley are three under.
1845: Rory McIlroy finishes with a round of 71 for one under. He was three under after six but dropped two shots before ending with eight straight pars.
1840: From Bighangers on 606: "Rollercoaster round of the day award: Camilo Villegas - birdie, par, par, bogey, birdie, birdie, birdie, bogey, bogey, birdie, par, bogey, bogey, bogey. To leave him +1 and he's still got four holes left! Any idea what he'll do?"This is like Play Your Cards Right - higher than a par, it's a bogey...
1830: Don't forget team, that this week's USPGA venue Hazeltine has significance for British players. It's where Tony Jacklin won the US Open in 1970, where Luke Donald won US college golf's NCAA Championship and where Richie Ramsay won the US Amateur. Could that mean something? Could it? Er, no.
1825: Justin Rose has launched a back-nine recovery and has climbed from three over after 10 to level after 14 with three birdies in four holes.
1818: Padraig Harrington is proving he has "bouncebackability" as he adds a second straight birdie at the 3rd, his 12th, to edge back to three under, one off the lead.
1815: Lee Westwood news, and everyone's favourite Worksop professional called Lee is keeping station at level par after 11 having traded two birdies with two bogeys.
1809: Uh-oh. Hello there. Make that a four-way tie. You know who - and in case you don't I'll tell you, it's Tiger Woods - is now four under with a birdie on the long 3rd, his 12th.
1805: We've now got a three-way tie for the lead as Robert Allenby and Alvaro Quiros make up ground. Leaderboard: -4 R Allenby (after 14), A Quiros (11), M Bradley (10) -3 H Mahan (12), T Woods (11), S Hansen (10)
1800: Nick Dougherty fans may be dismayed to hear their man is now eight over after 14 holes. The likeable Liverpudlian began with a double bogey, had another on the 12th and has made four other bogeys.
1750: Padraig Harrington slipped to one under after a bogey at the par-four 1st, his 10th, but he has bounced back with a birdie at the 2nd.
1745: We have a new leader in Michael Bradley of the US at four under, through nine. Tiger Woods creeps to three under with a birdie at the 2nd, his 11th. Northern Ireland's Graeme McDowell has edged to two under with a birdie at the par-three 13th, while countryman Rory McIlory, who reached three under after six holes, has steadied the ship with fours pars following bogeys at the 16th and 1st. He's now one under with four to play.
1740: From anonymous via text: "I'm tempted to bet on Steve Stricker to win. Your thoughts?" Not a bad shout, that. World number five, unsung player, a USPGA course would suit his type and the event often yields a first-major winner.
1730: Spain's big-hitter Alvaro Quiros climbs into the lead at four under with a fourth birdie at the par-three 17th, his eighth hole, but a bogey at the 18th drops him back into the leading pack alongside Robert Allenby, Dustin Johnson and Michael Bradley. Tiger Woods and Padraig Harrington reach the turn two under. Rob, who are you tipping to win? Sergio seems to be going along nicely, under the radar. Don't count out Harrington successfully defending. Please not Tiger."
Do you mean you don't want Tiger to win, or don't want me to tip Tiger? I certainly wouldn't count out Harrington or Sergio and I might be tempted by Ross Fisher, if his mind is back on the job.
Tiger is obviously the super-hot favourite and rightly so, but if it's not his week it really is wide open. Sorry to sit on the fence, but it's there for the taking if you are reasonably long, have a good short game and hole some putts. Like most weeks, really.
1710: So here's a brief rundown of the state of play: Leaderboard:-3 Hiroyuki Fujita (Jpn), R Allenby (Aus), D Johnson (US), A Quiros (Spa)-2 P Goydos (US), N Green (Aus), M Goggin (Aus), P Harrington (Ire), S Micheel (US), T Woods (US), S Hansen (Den), M Bradley (US).
Woods and Harrington have played eight holes after starting from the 10th, while the leader is through 12.
Northern Ireland's Rory McIlory is one under after 11, the same score as countryman Graeme McDowell and England's Chris Wood (both after 10) and Spain's Sergio Garcia (after nine).
Ross Fisher is one over after 12, fellow Englishman Lee Westwood is one over after seven, while Anthony Wall and Justin Rose are two over and Nick Dougherty five over after 11.
Colin Montgomerie, Ian Poulter, Luke Donald, Oliver Wilson and Phil Mickelson are among the later starters.
1700: Afternoon all and welcome to live text coverage of the USPGA, the year's final major, from Hazeltine, Minnesota.
Padraig Harrington is the defending champion but world number one Tiger Woods is the scorching hot favourite to win after victories in his last two events, including last week's WGC-Bridgestone Invitational.
Harrington, leading by one late in the final round at Firestone, imploded with a triple-bogey eight on the 16th to finish four shots behind Woods in second.
The pair are grouped together again for the first two days at Hazeltine, along with 2002 winner Rich Beem.
Woods criticised referee John Paramor for putting the pair on the clock for slow play at Firestone, and in the run-up to the USPGA he defended his actions.
England's world number three Paul Casey was forced to pull out late on after failing to shake off a rib injury, while the other big news in the world of golf is that the sport is set to rejoin the Olympics in 2016 after a 112-year absence.
I'll be guiding you through the action for the next four days, following the same pattern - a round-up of the early play before live action later.
Updates will be regular and always up to date with the main action, but apologies if I can't describe every shot of all of your favourite players.
