RIO DE JANEIRO -- Golf being a game for a lifetime, Lydia Ko could be excused for never having made an ace. Shes just 19, remember.Then again, she has won 14 times on the LPGA Tour. She is the youngest player to win two major championships. She is the No. 1-ranked player in the world.And shes never had a hole-in-one?That changed for Ko on Friday in the third round of the womens Olympic golf tournament. And what a time to do it. Ko holed a 7-iron shot from 140 yards at the par-3 eighth hole to help her shoot 29 over the first nine holes and finish with a 65 that vaulted her into contention for Olympic gold.In blustery conditions that became more pronounced in the afternoon, Kos score was the best of the day and moved her up 20 spots into a tie for second, 2 strokes behind South Koreas Inbee Park.To do that at the Olympics, it doesnt get any better than that, said Ko, who is from New Zealand. But to put myself back into good position going into tomorrow, I think was a job well done going forward.Kos exploits help set up what could be a potentially blockbuster final day for Olympic golf, which will get started earlier than usual due to expected bad weather Saturday afternoon. A two-tee start will begin at 6 a.m. ET with Kos final pairing going off at 7:39 a.m. ET.She will be in that final group with Park, 28, who spent a good bit of time at No. 1 in the world and has 17 LPGA Tour titles, including seven major championships. A thumb injury has kept her from performing at her best this year, but Park has responded nicely during the Olympics, shooting scores of 66-66-70 to position herself for a gold medal.Joining them in the last group will be American Gerina Piller, who has never won on the LPGA Tour but has played inspired golf this week. At a Tuesday news conference, Piller got emotional just talking about the idea of getting on the medal stand. Now, after a third-round 68, she could be just a day away.And that is not to count out the likes of Shanshan Feng of China or Charley Hull of Great Britain or a couple of other South Koreans: Amy Yang and In Gee Chung. They are all within striking distance of a medal, potentially even gold.All of that seemed unlikely for Ko after a lackluster start to the tournament. The pre-Olympics favorite, Ko opened 69-70 and trailed Park by 7 shots.But the New Zealander got hot on the first nine Friday, making birdies at the first, fifth and sixth holes before her ace at the eighth. She then struck her approach to 3 feet at the ninth for another birdie and an outward nine of 29 strokes.The hole-in-one was her first anywhere, somewhat surprising given her success around the world to this point.I was just [recently] talking to someone and I said, Ive actually only made a fifth of a hole-in-one because I made a hole-in-one for a double[-bogey] in a practice round, so I really cant count it, said Ko, meaning that she had hit two balls in a hazard before holing the third for a 5.This is the first one in practice rounds or tournaments included, and I almost didnt know how to react. Because its the first one and the wind is blowing and I havent had the best of luck when it comes to hole-in-ones.I would have loved to, like, done a dance or jumped up and down, but in that situation, I think I was almost trying not to cry, and then I realized, hey, Ive got 11 more holes, get out of it.Ko then made nine straight pars to close out her round in some of the toughest conditions. That put her in the last group for Saturdays final round. In Round 3, Ko hit 15 of 18 greens in regulation.I see a girl who is way beyond her years, said Paul McGinley, the 2014 European Ryder Cup captain who has served as a team leader for the Irish golfers the past two weeks; he watched Ko on Friday while she played with Irelands Leona Maguire.Shes very mature as a golfer and in control of her game. She understands her game, her swing, and she is very proficient at her craft. And she stays in her own mindset. Doesnt play anybody elses game. Doesnt get caught up in the emotions of a good hole, bad hole. And as I say, a girl who seems to be very mature as a golfer.Those attributes have served Ko well in an amazing career as a teenager, one that has a chance to get even better Saturday.Ever since 09, I was only 12 then, Ive imagined myself to be able to represent New Zealand at the Olympics, Ko said. To be here and especially on the first day, the first hole, I almost needed to pinch myself if I was really here in Rio and really competing in the Olympics.To be able to stand on that podium, its almost more than what you would imagine. Yesterday, New Zealand had five athletes who got to stand on the podium and I said, Wow, what a feeling it would be to put my contribution and stand on the podium for New Zealand, too. Just start imagining and dreaming about it.But you never know with the game of golf. Things can change so quickly.Jason Varitek Red Sox Jersey .

LOUIS -- Theres no telling how these wacky World Series games will end. Joe Kelly Jersey . SIMONS ISLAND, Ga. Ian Kinsler Jersey . The quest begins with what is supposed to be an easy one, although Germany has traditionally been a stubborn opponent to Canadian teams at international tournaments.The Washington Redskins have signed Pro Bowl tight end Jordan Reed to a five-year contract extension.The deal, which is reportedly worth $50m with $22m guaranteed, will keep the 25-year-old Reed in Washington through 2021.Reed, who was the teams third-round pick out of Florida in 2013, had his best season last year, with career highs in catches (87), yards (952) and touchdowns (11). He also had a big game in Washingtons post-season loss to Green Bay, catching nine passes for 120 yards and a touchdown.Despite his breakout season in 2015, Redskins head coach Jay Gruden believes Reed is only beginning to scratch the surface of his vast potential.He can get a lot better, thats the scary part, Gruden said. He is a very natural gifted route running tight end with natural hands and great ability to run after the catch. Reed (No 86) caught nine passes for 120 yards against Green Bay in the pplay-offs As he gets bigger, more confident, bigger frame as he works out with [strength and conditioning] coach [Mike] Clark in the weight room, hes going to be more of an impact in the running game which is only going to help him also in the passing game with the play actions.ddddddddddddSo hes going to keep getting better and better, got to keep in healthy, hes got to keep working and great things will be on the horizon for Jordan.The biggest concern to date with Reed is his ability stay healthy. He missed Week 5 and 6 of the 2015 season with a concussion and he has played in just 34 of 48 possible regular-season games to date in his career.Reed becomes the third tight end to sign a big-money extension in the NFL this off-season, following Zach Ertz of the Philadelphia Eagles (five years, $42.5m) and Travis Kelce of the Kansas City Chiefs (five years, $46.8m).Also See:NFL VideoRookies guideNFL on Sky SportsPundits ' ' '
