RIO DE JANEIRO -- Australia turned to the best sister act in swimming to hold off an American team anchored by Katie Ledecky.Give the gold to Cate and Bronte Campbell.And a world record, too.The Campbells carried their squad to victory in the 4x100-meter freestyle relay Saturday night at the Rio Olympics, with little sister Bronte snatching the lead from Dana Vollmer on the third leg and big sister Cate pulling away from Ledecky on the final down-and-back for a time of 3 minutes, 30.65 seconds.The Aussies broke their own mark of 3:30.98 set two years ago.That wasnt the only world record to fall on a late night of swimming to kick off the games. Shaking off repeated frustration on the sports biggest stage, Katinka Hosszu of Hungary crushed the world record in the womens 400 individual medley to make the first Olympic medal of her career gold.Also, Japans Kosuke Hagino ended American dominance in the mens 400-meter individual medley, while Australias Mack Horton took down Sun Yang of China without giving his bitter rival so much as a passing glance.The victories by Horton and the womens relay team capped an impressive first night for an Australian team that captured only one swimming gold medal in London four years ago.Theyve already eclipsed that total, with seven more nights to go.Meanwhile, the powerful American managed three silvers but couldnt reach the top step on the podium.Simone Manuel and Abbey Weitzeil did their best in the relay, giving the U.S. a lead at the midway point. But Bronte Campbell was more than a second faster than Vollmer, who had competed about an hour earlier in the semifinals of the 100 butterfly, and Ledecky was no match for Cate Campbell, the world-record holder in the 100 free.The U.S. had to settle for silver in an American-record time of 3:31.89, extending a gold medal drought in the event that goes back to the 1996 Atlanta Games.Still, it gives Ledecky a strong shot at capturing five medals in Rio. Shes favored in the 200, 400 and 800 freestyle events, and could take another gold in the 4x200 free relay.Canada claimed the bronze in 3:32.89.Hosszu, known as the Iron Lady for her grueling schedule, had an especially sweet triumph. She had captured nine medals -- including five golds -- at the world championships but never won an Olympic medal. She defiantly pumped her chest before breaking into a huge smile.She had led all the way and touched in 4:26.36, easily eclipsing the record of 4:28.43 held by Chinas Ye Shiwen. Hosszu even had time to turn toward the scoreboard and watch Maya DiRado of the United States touch in 4:31.15 to take the silver medal. Mireia Belmonte Garcia of Spain claimed the bronze in 4:32.39.Elizabeth Beisel of the U.S., the silver medalist at the 2012 London Games, finished sixth.Hagino took gold for Japan by holding off Chase Kalisz of the United States, becoming the first non-American to win the grueling event since 1992.Hagino and Japanese teammate Daiya Seto raced away from the field on the butterfly and backstroke legs before Kalisz began to close the gap. The American surged past Seto on the breaststroke and set his sights on Hagino.But the Japanese swimmer, who settled for bronze in this event at the 2012 London Games, held on to win in 4:06.05. Kalisz settled for the silver in 4:06.75, while Seto grabbed the bronze in 4:09.71.Ryan Lochte was the defending Olympic champion, but he finished third at the U.S. trials and didnt even qualify. Michael Phelps was the champion in 2004 and 2008, but hes dropped the 400 IM from his program. Tom Dolan was a back-to-back champion in 1996 and 2000.Tamas Darnyi of Hungary won gold at the 1992 Barcelona Games.Hortons victory came at the expense of Sun, the defending Olympic champion. The Aussie grabbed the lead for good on the next-to-last lap and held off the hard-charging Chinese star, who won both the 400 and 1,500 free at the 2012 London Games.What happened after the race was even more dramatic.The bad blood between the two was on display for all to see as Horton celebrated after the race without even acknowledging the runner-up. Sun made a move as though he wanted to congratulate Horton, but the winner looked the other way.They wound up climbing out of the pool side by side but never looked at each other. Hortons winning time was 3:41.55, just 13-hundredths of a second ahead of Sun. Italys Gabriele Detti rallied past American Conor Dwyer, the top qualifier in the prelims, to take the bronze in 3:43.49.After the prelims of the mens 400 freestyle, Horton was asked about a reported incident between the two at the practice pool earlier in the week. The Aussie said Sun splashed me to say hello, and I didnt respond because I dont have time for drug cheats.Sun served a three-month suspension for using a banned stimulant in 2014.Horton and Sun finally gave each other a begrudging handshake on the medal stand.---Follow Paul Newberry on Twitter at www.twitter.com/pnewberry1963.

Even as the clock ticked down toward the midnight expiration of Major League Baseballs labor agreement and a potential work stoppage, MLB had yet to schedule a lockout vote by owners, sources told ESPN late Wednesday afternoon.While that was viewed by people around the sport as another hopeful sign of progress toward a new labor deal, sources said owners have been told by MLB to be on alert Wednesday night, in case theres a need for an emergency vote either to ratify an agreement or to lock out the players if negotiations collapse.Meanwhile, the two sides continued to talk and, by Wednesday afternoon, had been negotiating almost continuously for more than 24 hours, on little or no sleep. Multiple sources continue to report they have made significant progress, but had yet to reach agreement on what appeared to be the last remaining major issue of disagreement: how a revised competitive balance tax (a.k.a., luxury tax) would function.Sources said the two sides have discussed significant changes to the tax, which has been assessed for more than a decade on teams that go over a negotiated payroll threshold. However, the players have balked at proposals they viewed as acting like a de facto salary cap by imposing penalties so stiff on big spenders that no team would opt to exceed the threshold.USA Today reported Tuesday that owners wanted to keep the threshold at $189 million in the first year of the agreement, which would mark the fourth consecutive season at that figure. Under the owners proposal, the threshold then would increase incrementally in future years.Players have asked for an immediate increase that reflects the sports steep rise in revenues over the last several years. The sides also have differed on tax rates, and potential other penalties, for teams that exceed the threshold several years in a row or exceed it by many millions of dollars.However, if the sides can reach agreement on how the tax would work, its believed that a number of other changes would then fall into place. Other provisions of the new agreement would be expected to include:Teams that sign a premium free agent would no longer have to give up a draft pick to the team that lost that playyer.dddddddddddd It is expected that teams losing those players still would receive a pick, however.Although owners pushed for months to include international players in the amateur draft, they dropped that demand this week, sources said. In its place, teams would work under a revised system of bonus pools that are expected to place hard limits on how much each club can spend to sign foreign-born players.Roster size would increase from 25 players to 26 through the end of August, then would jump to either 28 or 29 players from Sept. 1 on, instead of the current 40.The sides have talked about starting future seasons four or five days earlier than in the past as a means to give teams more days off during the regular season. The sides also have discussed scheduling more day games when teams face long flights following those games.There would be changes to baseballs revenue-sharing formula which would affect both payers and recipients. Details of those changes remain unknown.The sides have discussed numerous changes to the June amateur draft. Those changes could include everything from a revamped slotting system to trading picks. Details have yet to emerge.It is expected that tougher penalties would be imposed on players who violate baseballs joint drug agreement. A number of players have spoken publicly about the need for longer suspensions for those who test positive for performance-enhancing drugs.Changes also are likely in baseballs domestic-violence policy. Details have yet to emerge.The sides have discussed the possibility of playing games outside North America during the regular season in future seasons. It isnt known yet exactly where those games would be scheduled, but commissioner Rob Manfred has said publicly he would like to see regular-season games played in London.The agreement also would address numerous other issues, from service-time rules to expansion, from replay to pace of game, from meal money to ways to discourage tanking. However, it might be as much as several weeks until all of those changes will be known publicly. cheap falcons jerseys cheap ravens jerseys cheap bills jerseys cheap bears jerseys cheap bengals jerseys cheap cowboys jerseys cheap lions jerseys cheap texans jerseys cheap colts jerseys cheap jaguars jerseys cheap chiefs jerseys cheap rams jerseys cheap dolphins jerseys cheap vikings jerseys cheap saints jerseys cheap giants jerseys cheap jets jerseys cheap eagles jerseys cheap steelers jerseys cheap 49ers jerseys ' ' '
