Watson pars the 9th. That means he's managed to string together successive pars for the first time today.
Our dynamic Scandinavian duo of Blixt and Born both par the 10th to retain a share of the lead. Two birdies and n dropped shots for the playing partners so far.
Westwood facing a testing 14 footer for par on 17th...
Kuchar strokes home a confident putt on the 15th for a birdie. He goes to five under and we've now got a very cosy four way tie for the lead.
Westwood couldn't make the putt on 17 and slips back to two under for the day and for the tournament. Meanwhile just seconds after Kuchar strikes, Watson hits back with a birdie of his own on 10 and the American is once again the standalone leader.
It's late afternoon at Augusta but the sun continues to shine brightly. The breeze is picking up slightly but not a major factor yet.
A brief hiatus in proceedings as our leading protagonists all seem to take a collective pause for breath and throw in a succession of pars. Who's going to produce the next surge?
Justin Rose reflects on his day's work.
"It was a rollercoaster of a round. I got into a nice
rhythm around the turn, then picked up an eagle at 13 and got a bit
lucky at 15. Those of us in the clubhouse are in the hands of the leaders, but I am in a much better place than I was on Thursday."
Blixt drops his first shot of the day on the 11th to drop to four under. Westwood safely pars the 18th to record a two under round of 70 and give himself something to shoot at on Sunday.
With all the remaining players on the back nine, Jimenez's 66 earlier looks unlikely to be eclipsed. The worst round of the day so far? That dubious honour unfortunately goes Brandt Snedeker who hacked his way around Augusta in an eight over par 80. Ouch.
Kuchar strings together three successive birdies on 13, 14 and 15 and then follows up with two back-to-back pars on 16 and 17. *solid golf*
Watson comes up short with a birdie putt on the par three 12th and stays at six under.
Bjorn & Blixt both find the water in front of the green on the par five 13th. Dropped shots coming methinks...
Kuchar hits the hole with a long range putt on the 18th but it doesn't go in. It's a dropped shot and his day's work is done. It's a round of 68, four under. He's also four under for he tournament and now a serious contender for the Green Jacket tomorrow.
*Smug* As predicted, Blixt and Bjorn both shoot a bogey six on the 13th and for the first time in a long time Watson is sitting on a two-shot lead. He's also looking nailed on for at least a birdie on 13 t extend his advantage...
Watson putting uphill for an eagle on 13...
...misjudges it badly, leaving it 10 yards at least short and suddenly his birdie is in serious doubt...
...yes, spurned chance there. Two great drives but a dismal three putt and it's only par.
Birdie for Senden on 13 and the Aussie is beginning to repair some of the self-inflicted damage of hid opening seven holes when he dropped five shots in rapid succession. He's still two over for the day but two under for the tournament.
Watson wallops it off the tee at 14 and, as usual, the ball seems to defy the laws of physics, gravity and golf and just keeps flying. Bubba can hit a serious ball.
Spieth sinks his birdie putt on 15 and he emerges from the pack to go five under and second on the leader board, just one shot adrift of Watson.
Jamie Donaldson finishes what has been a difficult day at the office, bogeying the 18th for a round of 76. One to forget for the Welshman...
We're nearing the end of the day and barring some real pyrotechnics or a meltdown, we're going to get an intriguing final day's golf with perhaps 15 players who will believe they have can win The Masters.
Stephen Gallacher leaves the course after recording a disastrous nine over par 81. Four double bogeys did for the Scotsman today.
Blixt back in form with a birdie on 15th. That's the Swede's first birdie since the 9th.
In contrast, Bjorn bogeys the 15th to lose ground on his playing partner
Jim Furyk drops a shot on the 18th, which is rather jolly annoying for him. It's an evens 72 today for the vastly experienced American but he's still in the mix for tomorrow.
Hmmm, a second successive birdie for Blixt as he nails his putt on 16. Moves into joint second with Speith.
Watson has now posted five pars on the bounce after holing on the 15th. After what was a rollercoaster first 10 holes, he's settled down into a steady rhythm.
