Rory McIlroy chasing career Grand Slam at Augusta
McIlroy opens with one-under-par 71
Jordan Spieth leads by three on -8
England's Justin Rose tied second on -5
Defending champion Bubba Watson finishes -1
Sergio Garcia -4; Paul Casey -3; Tiger Woods +1
Image source, ReutersYou could say Tiger Woods has had a topsy-turvy start - bogey-birdie. The chaos continues.
A monster drive on the par four third leaves him with a chip from 24 yards and he chunks it, a clink and a clank, 21 feet past the hole. Still a birdie putt. It'll probably drop such is his volatile start.
He doesn't, taps in for par and Rose ends with par - five under for the day, joint leader.

"It is all about the weather and the conditions mean scoring is easier today. The greens are still full of grass, they are not that light brown colour that they will be by Saturday and so there are birdies coming out of the trees."
Image source, Getty ImagesEnglish duo Ian Poulter and Lee Westwood are in with 73s - not the starts they would have wanted, but not wrecking rounds either. Woods has almost found the green with a three wood off the tee at the par-four third. Whatever his recent form, he won't be leaving anything out on this course.
Image source, Getty ImagesRose has made par putts of eight and nine feet on 16 and 17 to stay tied for the lead, that's the stuff of a Masters champion. Woods drains a four-footer at the par-five second to get back level. McIloy made that birdie putt on 13, is back level, Mickelson walks away with a scrambling par to stay two under.

Image source, Getty ImagesThe 28-year-old from Sheffield was in the clubhouse on -1 after a round that included an eagle putt on the 13th. He tweeted: , externalNice first day!! Some lovely golf out there and a bit up n down on the greens!! Nothing better than a cheeky 60 footer!! Boom!!
Image source, ReutersMickelson's second at 13... splash, swimming with the bream in Rae's Creek. McIlroy, feet well above his feet... safely on. US Ryder Cupper Patrick Reed is in with a two-under 70, as is fellow American Kevin Streelman.

Image source, EPAMickelson bombs one down the middle at 13, McIlroy flirts with the trees. Two-time champion Jose Maria Olazabal is in with an ugly 79, not quite as ugly as 2003 champion Mike Weir's 82. Defending champion Bubba Watson is two under through 16...

Image source, ReutersHere's Woosie, with his second at 11. Best I've seen yet by some distance, not afraid of the drink. The 1991 winner from Wales is level. Woods walked away from the opening hole with a bogey after three-putting from 43 feet.
McIlroy's birdie attempt at 13 curls too soon and he stays +1. Mickelson rams in his par putt, stays -2. I hear Tiger has a five-footer for par at the first...
Image source, Getty ImagesBBC Sport's Ian Singleton at Augusta: "At the moment Augusta is sweltering. The course is packed with spectators in shorts sipping beer or soft drinks from their Masters 2015 plastic cups. These cups are clearly highly collectable with many carrying a stack of half a dozen empty ones to take home with them. The cost of a drink? $1.50 (£1.02) A club sandwich is $2.50 (£1.70)."
Image source, Getty ImagesIt's Mickelson to fire first at the 12th. Lefty has been feeling the effects of arthritis of late but that's a total misread, racing it a couple of feet high and five feet past. Casey right in the mix, he birdies 13 to join that group on four under, one off the lead.
Image source, Getty Images"I've had some frustrating moments," Tiger Woods told the BBC with a smile.
His relaxed demeanour has been a talking point this week, perhaps a man who appreciates just being at golf's most immaculate venue after a frustrating time of injury and poor form.
But asked what he's looking for come Sunday he coyly told BBC Sport: "I'd like to win. I'd like to get another green jacket, I've got four, I'd like five. That's why I was practicing so hard to get ready at the highest level."
We will know a lot more about his challenge in the next four hours.
Image source, Getty ImagesMickelson on tee at the par-three 12th... solid, indeed a touch better than solid. McIlroy's is about as good, two birdie chances. Woods is on in two at the first, but he's got a monster for birdie. Bill Haas birdies 13 to get to -4 and into a tie for third.
