SAN MARTIN, Calif. -- When Lydia Ko first came to a U.S. Womens Open four years ago, her hands were shaking from nerves. Now with two major titles under her belt by age 19, Ko is able to keep those emotions under control and project a picture of calmness on the golf course.Ko birdied the 18th hole to cap a 2-under 70 in the third round Saturday that put her in the lead at the U.S. Womens Open at 7 under, bolstering her chance for her third major title in less than a year.I think nerves are good because it means youre excited, Ko said. Youre ready. It means a lot to you. Youve got to be able to control it. But a little bit of nerves is always good. It can end up being a little bit of adrenaline.Whatever Ko is doing is working.She became the youngest woman to win a major last year at the Evian Championship and followed that up by winning the ANA Inspiration this spring. Now shes in contention for her first U.S. Open title after failing to make the top 10 in her first four appearances.Ko has a one-shot lead at CordeValle over 2009 winner Eun Hee Ji and Sung Hyun Park. Brittany Lang and Amy Yang are two shots back at 5 under, and Angela Stanford is in sixth place at 4 under.Im going to just try and enjoy it, just focus on the shot I have in front of me and not think about what everybody else is doing, Ko said. If I think that way, I wont get too carried away with what position I am at certain parts of the final day.Kos week at the Open got off to a somewhat shaky start. She was tied for 52nd after a 73 in the first round in the difficult afternoon conditions.But Ko got into contention with a 66 in the second round and then took sole possession of the lead on the final hole Saturday. Her approach shot spun back about 9 feet from the hole. She calmly sank the putt and then threw her ball into the stands in celebration.Ko is tied for the fewest putts through three rounds. She made two other long birdies Saturday, a 25-foot downhill putt on No. 3 and a long left-to-right swinging putt on No. 13 that she initially thought she had over-read.Thats what I was doing the majority of the day, she said. I said, Oh, man. And then I was kind of walking a little bit and then I saw the ball drop. So it kind of took me by surprise. So it was a lucky one.Ji has broken par all three rounds, with a 69 and 71 in the first two rounds followed by her 2-under performance on Saturday. She is looking for another LPGA Tour win after winning the Open at Saucon Valley seven years ago.Park, playing her first U.S. Open and second major ever, got off to a solid start with birdies on the sixth and eighth holes to move to 9 under. But fortunes quickly changed at the par-5 ninth when she hit her tee shot into a hazard for a penalty and ended up with a double-bogey.Lang birdied 14 and 15 and had the low round of the day at 68 to move to 5 under. Lang tied for second as an amateur in her first U.S. Open in 2005 but has been in the top five only once since then, in 2010.Ive been here before, and I think you really have to just get to work on what youre doing, because if you spend a lot of time thinking about where youre going to finish, youre going to drop down pretty quick, Lang said.Several other golfers are lurking close enough to make a push on Sunday. Danielle Kang is at 3 under and fellow Americans Cristie Kerr, Stacy Lewis and Kris Tamulis are among seven golfers five shots back at 2 under.Theres no doubt I have to shoot at least 4 to 6 under, Id say, tomorrow to have a chance, Kerr said. It depends on the wind and the weather and the pins. Sometimes they like to set it up easier on Sunday and people get some low scores. I dont know what theyre going to do, but I have to be prepared for anything. If the conditions are easier, I have to be prepared to go low.The highlight of the day might have been Lee Lopezs ace on the 191-yard, par-3 12th hole. Lopez is at even par for the tournament.

Sebastian Vettel does not think Ferrari needs to turn the world upside down after a disappointing British Grand Prix, saying the race simply did not suit the team.Vettel could only manage ninth position at Silverstone in a race which saw him spin out on several occasions. Ferrari had hoped to challenge Mercedes coming into the weekend but has lacked performance throughout and was out-qualified by both Red Bulls on Saturday.Vettel started 11th after serving a gearbox change penalty and admitted it was difficult to fight back through the field after his initial spins.It was not an easy race, Vettel said. For sure in these conditions its easy to get it wrong and make a mistake. I think you saw a lot of people going off track, unfortunately I was one that went off track and spun. So that lost us a lot of time but I think overall it was quite tricky with the conditions until the end with a dry line and wet patches here and there. So I think the fact that then I was stuck in traffic for some laps doesnt help with looking after tyres etc. So you lose the rhythm a little.As a result you can see we werent quick enough to challenge for a podium this weekend, so theres plenty of things for us to understand and learn. In this regard I think it has been a weak race for us but I dont think we need tto turn the world upside down.dddddddddddd We know the car that we have and I think if you look at the performance yesterday it was more or less in line. Again, its not the most competitive weekend for us, but for sure today we seemed to lose a little bit compared to the people ahead.Vettels ninth could have become tenth because of a five-second time penalty incurred after forcing Felipe Massa wide at Turn 2, though he managed to build a big enough gap to Daniil Kvyat to hold the position. Vettel felt the penalty was harsh.Not much to say. I was on the inside, he went a little bit wide at Turn 1, he was on the inside for Turn 3. We basically hit the brakes at the same time, I was trying to turn in and every time I tried to turn in I lost the car, lost the car, lost the car. So I had to open up and went wide myself.Obviously there was no intention to force him off the track because I was going off the track as well so it wasnt something that I controlled, but for some reason the stewards took the view that I did that on purpose and I got the penalty. But I think it was a racing incident.The incident also earned Vettel two penalty points on his superlicence. ' ' '
