Australian amateur Curtis Luck and compatriot Lucas Herbert shot five-under-par 67s for a share of the lead as Jordan Spieth struggled with his putting in the opening round of the Australian Open. Luck, the US and Asia-Pacific amateur champion, mixed seven birdies with two bogeys to upstage playing partners Spieth (69) and former US Open champion Geoff Ogilvy (70) after their early morning tee-off at a sunny Royal Sydney.World No 5 Spieth managed just one birdie on his front nine but three more after the turn kept him well in contention despite a bogey after driving through the green on his penultimate hole. A share of eighth, two shots off the pace, was a satisfactory return for the American as he re-tuned his putter after a six-week break.I made a couple of putts from outside of five or six feet but that was it, said the 23-year-old.But theyll start falling and once a couple do and I start finding that confidence, the hole looks a bit bigger, thats when we can really open the floodgates.I certainly believe in my ability the rest of this week. I didnt find the hole to be very big today. Adam Scott endured a frustrating opening day at Royal Sydney Adam Scott missed out on a chance of a second Australian Open title when Rory McIlroy pipped him on the final hole the last time the tournament was played at Royal Sydney in 2013.Thursday was another disappointing day for the world No 7 - nothing was good about that round was his verdict - turning around at one under before four bogeys and two birdies on the back nine left him with a one-over 73.Luck is one of a string of up-and-coming amateur Australians looking to join Scott and world No 1 Jason Day in the top ranks of the game and he was clearly not intimidated by being grouped with two Major winners.

Lucas Herbert sets the early pace alongside Luck It was also a matter of what might have been for Australian veteran and Royal Sydney member Peter OMalley, who chipped in from a bunker to take a share of the lead at the 14th but dropped back after finding the trees at the 18th.OMalleys 68 gave him a share of third place with New Zealander Ryan Fox, New Zealand-based German David Klein and fellow Australians Ben Clementson and Adam Burdett.Upgrade to Sky Sports now to watch Man Utd v Arsenal this Saturday and get the first six months half price!

Mercedes boss Toto Wolff says a miscommunication caused by the timing of the teams flight home caused the short-lived protest of Max Verstappens driving after the Japanese Grand Prix.Verstappen held off Hamilton late in the race at Suzuka with a move Wolff later called refreshing but potentially over the line. Mercedes formally protested Verstappens driving, but by the time it was lodged the Dutchman and Lewis Hamilton had already left the circuit.Wanting to speak to both drivers, the FIA said it would have to defer the protest -- and therefore keep the result provisional -- until this weekends U.S. Grand Prix. A confusing couple of minutes followed, where Hamilton deleted one tweet and then questioned the teams protest in another, before Mercedes withdrew the complaint.Wolff says team representatives still at the circuit had been unable to contact him at the crucial moment a decision had to be made about lodging a complaint.It was a miscommunication, he explained in Austins Friday press conference. When we left the circuit, I said that the Verstappen manoeuvre was a hard manoeuvre but probably what we want to see in F1. It is refreshing and I think the drivers need to sort that out among themselves on track. We decided not to step in.Then there was an unfortunate coincidence that we took off and left and the team had a minute to decide whether to protest or not. Annd that is what they did.dddddddddddd. Once we were able to communicate again, which was 30 minutes after take-off, we decided to withdraw the protest.Hamiltons tweets came after a weekend which saw the Englishman at odds with the media for what he felt was disrespectful to the media for the reporting of his use of Snapchat in a press conference. The world champion has looked much more relaxed in Austin this weekend and Wolff thinks Suzuka was just an example of pressure getting the better of him.I think that generally all of us we underestimate the pressure that is on these guys. A couple of races before the end of the season there is all to win and all to lose. And I guess after Malaysia when he was in the lead, 25 points to take, the engine blew up.That was a very difficult situation for him to cope. As cool as someone might seem to the outside, inside it kind of eats you up -- and that may be why the weekend in Suzuka was a bit difficult for him. He knows exactly
