SPRINGFIELD, N.J. -- Jimmy Walker overcame a few wild tee shots with four birdies on the back nine for a 2-under 68 and a one-shot lead over defending champion Jason Day going into the final round of the rain-plagued PGA Championship.This already was shaping up as a major like no other.Even as Walker and Day were finishing their rounds, the fourth round already had begun on rain-soaked Baltusrol. The PGA of America chose not to redo pairings for the final round because it was the only chance to finish by Sunday.Then, the PGA decided to play preferred lies for the final round, which had not happened in a major in more than a half-century. That means players will be able to lift, clean and place their balls anywhere but the rough.Walker, who was at 11-under 199, was among 10 players who didnt even hit a shot Saturday because of storms that flooded the Lower Course at Baltusrol. He had never contended in a major until this week, and went into the final 18 holes having been at least tied for the lead all three rounds.I made a couple of tentative swings early, Walker said. I just said, `Trust it man, youre swinging it good. Keep the pedal down.The final round figured to be the toughest, especially with the cast of characters behind him.Day surged into the lead with a 75-foot birdie putt on No. 7 from the front to the back of the green, and a tee shot to 4 feet on the par-3 ninth. Walker and Robert Streb, who shot a 63 on Friday to share the 36-hole lead, began to struggle off the tee and on the green, both dropping two shots behind Day at one point.Day settled into a string of pars on the easier back nine until finishing with a birdie for a 67. It was his seventh straight round of 68 or better in the PGA Championship.I went a stretch of eight holes without a birdie and I needed one to get some motivation for the fourth round, Day said. But I played some nice golf out there.He is trying to join Tiger Woods as the only players to win the PGA Championship in consecutive years since it went to stroke play in 1958.It would be really nice to get that second major under my belt, Day said. I dont want to win just one for my career.Unlike the British Open two weeks ago, this is hardly a two-man race.Henrik Stenson, who won the duel at Royal Troon with a record score in a major, piled up enough birdies on the back nine for a 67 and was two shots behind in his bid to join Ben Hogan as the only players to win back-to-back majors at age 40.Brooks Koepka, playing for the first time since the U.S. Open because of an ankle injury, had a bogey-free 66 and was two shots behind. A big week by Koepka could all but clinch a spot on his first Ryder Cup team.Streb, meanwhile, didnt make his first birdie until the 17th hole, only to three-putt from just inside 8 feet for bogey on the 18th and a 72. He was four shots behind, along with William McGirt (66) and Hideki Matsuyama (67).Jordan Spieth finished with eight straight pars, missing good birdie chances along the way, and had to settle for a 69. That left him seven shots behind, which would require a record-tying comeback at the PGA Championship to have any chance.Patrick Reed also wasted a good opportunity, making double bogey on the sixth hole and shooting 70 to finish six shots behind.The PGA Championship was trying to avoid its second straight Monday finish at Baltusrol. Phil Mickelson won on a Monday in 2005. Rain began to fall as the leaders finished the third round, though play kept going. Any stoppage in play was sure to mean one more day before the Wanamaker Trophy is handed out. Los Angeles Rams Jerseys .

LONDON -- The fact that Serena Williams has a powerful serve was underlined at Wimbledon, as she recorded the fastest opening shot (124 mph) at the tournament on her way to her 22nd Grand Slam title.But on at least five other indices including women who played at least three Wimbledon singles matches, Williams didnt even feature in the top five.So, who ran the farthest, hit the fastest groundstrokes and put the most spin on the ball?Court coverageThe distance run per match could produce a list of the hardest-working players ... or the players who were given the runaround the most by their opponents. Either way, these five women -- four of whom ran an average of more than a mile each time -- certainly covered some ground.1. Agnieszka Radwanska: 1,988 metres2. Carla Suarez Navarro: 1,712m3. Ekaterina Makarova: 1,666m4. Svetlana Kuznetsova: 1,637m5. Venus Williams: 1,591mFastest forehandsThe only speeds which are usually displayed on court at Wimbledon are for serves and the fastest of the womens top 120 mph. However, second serves usually come in a lot slower and, when compared with these average forehand speeds, are not always that much more powerful.1. Madison Keys: 77 mph2. Misaki Doi: 75 mph3. Coco Vandeweghe: 74 mph4. Yaroslava Shvedova: 74 mph5. Svetlana Kuznetsova: 73 mphBrutal backhandsForehand power is a common strength, but backhand brilliance less so. Many players in the modern era hit double-handed on that side to try to get more speed and control and, given the fastest averages below, it seems to have been working.dddddddddddd1. Madison Keys: 75 mph2. Coco Vandeweghe: 72 mph3. Carla Suarez Navarro: 72 mph4. Venus Williams: 71 mph5. Svetlana Kuznetsova: 71 mphForehand topspinThe speed of a shot might be relatively easy to measure, and the values are certainly part of the broader tennis lexicon. The number of revolutions per minute (rpm) a player puts on the ball is talked about less but can be significant. The revolution count is a good indication of the amount of spin put on a ball as well as the technical execution of the shot, and these averages are impressively high.1. Svetlana Kuznetsova: 2,508 rpm2. Carla Suarez Navarro: 2,334 rpm3. Coco Vandeweghe: 2,333 rpm4. Misaki Doi: 2,294 rpm5. Madison Keys: 2,193 rpmBackhand topspinTopspin is most frequently a forehand weapon and is much harder to execute on the other side, but the desire to give a ball a higher flight and more bounce and forward momentum on landing is still very much there. These five women have good technique.1. Carla Suarez Navarro: 2,120 rpm2. Yaroslava Shvedova: 1,960 rpm3. Anastasia Pavlyuchenkova: 1,829 rpm4. Lucie Safarova: 1,828 rpm5. Madison Keys: 1,800 rpm* All statistics courtesy of Hawk-Eye Innovations. ' ' '
