ROGERS, Ark. -- Mika Miyazato changed putters following a missed cut at a tournament in Texas in April, hoping to put a quick end to what had been a disappointing season so far. Miyazatos move has paid off in the form of her top three finishes of the year -- including her best round of the year on Friday. The Japanese golfer birdied six of 10 holes in the middle of her round to shoot a 6-under 65 and earn the first-round lead at the LPGA Tours NW Arkansas Championship. The round was only Miyazatos second in the 60s this year, topping the 69 she opened her year with in Thailand in February. Miyazato finished in a tie for second at the event last year, missing a 15-foot birdie putt on the final hole to finish a stroke back of winner Ai Miyazato. The Japanese golfer hit 16 of 18 greens in regulation on Friday to finish a shot ahead of So Yeon Ryu and Angela Stanford at 5 under. "Well, I was disappointed last year, but I was very good friends with Ai, like (an) older sister (to) Ai," Mika Miyazato said. "It was a good experience last year." Ten golfers are two shots back of Miyazato at 4 under, including local favourite Stacy Lewis, who played collegiately at the nearby University of Arkansas. World No. 1 Inbee Park is four shots off the lead, as is Charlottetowns Lorie Kane, after shooting a 2-under 69. Maude-Aimee LeBlanc of Sherbrooke, Que., also shot a 69. Sara-Maude Juneau of Fossambault, Que., and Stephanie Sherlock of Barrie, Ont., shot 71s. Torontos Rebecca Lee-Bentham carded a 73. It was Miyazato, however, who bested the rest of the star-packed field on Friday -- a group that included 97 of the top 100 on the money list heading into next weeks U.S. Open. She did so despite a disappointing year so far, one that had her enter this week 46th on the money list and 77th in scoring average. Still 15th in the world rankings, Miyazato had struggled mightily with her putting -- ranking 133rd on the tour. She looked comfortable from tee to green on Friday, hitting 16 greens in regulation and making several key putts. That included a 10-footer to save par on No. 16, on that followed her final birdie of the day on the par-3 15th. Miyazato was heartbroken after last years close call at the tournament, which would have been her first victory on the tour. She went on to win her first LPGA event later last year at the Safeway Classic, and shed like nothing better than to add to that total this weekend. "I think (the) second win is more difficult than the first win," Miyazato said. While Miyazato posted the lowest score of the day during her morning round, Lewis enjoyed the largest gallery during the afternoon in front of her Arkansas fans -- who serenaded her with a call of "Woo Pig Sooie" after she hit the green on No. 17. The Texas native missed her birdie putt on the hole, but she closed out her round with an up-and-down birdie out of the greenside bunker on the par-5 18th. The world No. 2 earned an unofficial win at the rain-shortened event as an amateur in 2007, but she hasnt finished higher than eighth since. She had no such problems on Friday, hitting 13 of 13 fairways and closing with four birdies on the back nine. "I got off to a little bit of a slow start, just wasnt really making any putts on the front and then kind of relaxed there on the back, made a few putts," Lewis said. "... I was feeling good. Even when I was even par, I was feeling good about my game." The course at Pinnacle Country Club played slow and soft earlier this week following heaving rains in recent months. However, hot and humid conditions throughout the week began to speed things up on Friday -- which was just to the liking of many of the golfers. Miyazatos took the early lead with her morning birdie binge, and her 65 held off a group of 12 golfers who are within two shots of the lead. Ryu posted her 66 while playing with Miyazato in the morning, while Stanfords 5 under came in the afternoon in Lewis group. The group at 4 under includes Lewis, Chie Arimura, Danielle Kang, Azahara Munoz, Beatriz Recari, Lisa McCloskey, Mina Harigae, Suzann Pettersen, Christel Boeljon and Sarah Kemp.Balenciaga Speed Trainer Cheap . -- In a span of seven Washington Redskins offensive plays, Justin Tuck sacked Robert Griffin III four times.

The sun shines -- albeit low in the sky -- but often the circuits are spotted with frost in the early mornings, and track temperatures are hardly representative of those seen during the season.In 2014 F1 had two pre-season tests in Bahrain, giving teams the opportunity to get to know the new hybrid power units in representative conditions. Next year will see dramatic design changes to the cars themselves, added downforce, and a new approach to F1 rubber. But despite the logic of testing somewhere warm next winter, paddock finances point to another two weeks in Catalunya.In an exclusive interview with ESPN, Pirellis Paul Hembery talked about the challenges ahead for F1s tyre supplier in light of the changes to cars and tyres alike for the 2017 season.The good news is, we do have a test programme, Hembery said. As weve made people aware, we have started a 24 testing day programme split equally between Red Bull, Ferrari, and Mercedes, who have kindly supported us by developing a version of the 2015 car with an aerodynamic package intended to simulate what will be the effect of the 2017 rule regulations. This of course is a huge step forward. Were making such a dramatic change to the tyre width.Challenges? The downforce increases are substantial. The performance requirements are to improve by five seconds compared to the 2015 lap times. In reality, having seen maybe a two-second improvement already this season, next year it is likely that we will substantially improve on the lap time.The initial simulation data that we have would suggest, as I say, that would be easily surpassed. Of course we wont actually see the real cars until we get through to pre-season testing next year. The change is vast, increasing the width of front and rear tyres by six and eight centimetres respectively, which looks good. It makes the cars look very dramatic, with both the front and rear track increased by 20 centimetres each. The intention there is that it will make it easier for teams to overtake; if theyre following another car [we want to ensure] that the tyres wont reach a temperature peak, which has stopped the drivers from overtaking on some occasions. Of course, that will only work if we also reduce the impact of the weight of the aero of one car from another. The suggestions are that that will be improved in the aero. I wouldnt say there is universal opinion on that.Testing their tyres has long been a problem for Pirelli, thanks to the sports understandable focus on keeping costs -- and team travel time -- to a minimum. But with such dramatic changes expected for 2017, Pirelli have finally managed to negotiate much-needed days of mule car testing. But are the agreed test days the ideal solution from a Pirelli perspective?I tthink if you said to somebody, how should you do it correctly?, youd go to a circuit where you race so you have all the data, and youd go in conditions that represent the conditions that youre going to race in, Hembery said.ddddddddddddIn January and February, we will have a good indication when we do our testing now with the three teams. Weve tested at Fiorano and Mugello in early August, where the temperature at the moment is very, very warm. So we will start to get some very clear indications of testing with the mule cars that we have this year. As I said, there is no substitution for getting on the actual cars, which we will get next year and at the moment were undecided where the locations are.From a purely tyre-maker perspective it would be better to be in somewhere warm during that period of time. In the past few years we have been to Bahrain, which allowed us to have a clear indication of the tyre performance at much earlier stage. I understand that teams believe there is a certain cost penalty for doing that, but then again it is a sport that has a few billion spent on it. If the willingness is there Im sure the funding can be found.One session in Bahrain would already be a big step, so we would know where we are during the season, Hembery continued. That might not be able to affect what we do for Australia, but it means we can start working earlier if there are changes needed. Were obviously aiming not to make changes, however the changes are so important that there may well be things that we understand only by going on the track with the 10 or 11 different chassis that we have in Formula One.And if the teams decide that they cant afford a warm-weather test, and we are restricted to a fortnights pre-season testing in Spain in February, what impact would that have on Pirellis ability to test effectively?We can do a lot with simulation and indoor drum testing, Hembery acknowledged. You do the majority of work there, but the interaction between car, tyre and tarmac still requires going out and testing and looking at the tarmac. If thats all been changed, it changes completely the dynamic of the package. In reality you still need to go out on the track and do that testing.We need to have a good understanding how the compounds are working to understand if weve got the scaling right between them, if we have the degradation levels right or whether its too low or too high. [The teams] are still asking for two-stop strategy, which will become harder with less degradation -- why would you change your tyres? At the moment it is primarily due to performance.If we want to have a quicker understanding of how the tyres or compounds in particular are performing, we would need to go to somewhere like Bahrain as early as possible.
