LAS VEGAS -- Super middleweight Claressa Shields, the two-time U.S. Olympic gold-medal winner, made her professional debut in action-packed style as she powered to a four-round decision victory against amateur rival Franchon Crews on Saturday night at T-Mobile Arena.Shields, a 21-year-old from Flint, Michigan, was the best female in amateur boxing and named the most outstanding fighter of the womens tournament at the Rio Games in August. She began her pro career by defeating Crews, a decorated amateur who had lost three times to Shields in the unpaid ranks.Shields beat Crews again in the paid ranks and did so handily, winning 40-36 on all three judges scorecards in a blazing fight. ESPN.com also had Shields winning 40-36. Shields victory took place on the undercard of her idol Andre Wards light heavyweight world title challenge against Sergey Kovalev.It feels so good to have just made my pro debut, Shields said. This is what Ive been training for. Im faster and I hit harder. And Im the better fighter. But Crews brought 100 percent, and I respect her for that. I hope to fight next in January or February.?As soon as the bell rang to begin the fight, Shields and Crews stormed toward each other with all-out aggression in what was a blazing first round. There were several heated exchanges, and they both landed clean punches. The action did not let up in the second round, but Shields appeared to get the better of Crews, even landing a heavy left hand as the round wound down.Referee Russell Mora twice warned Crews (0-1), 29, of Baltimore, for pushing Shields to the canvas and sneaking in some solid blows.Shields (1-0), who earned $50,000, was going hard for a knockout in the fourth round and rattled Crews, who made $10,000, with several hard punches.Its not what I wanted, but to be called on, last minute, for a fight of this magnitude, I am proud of myself, Crews said. We will fight again in the future.Shields, the most decorated female amateur in history who is also a four-time U.S. national champion and two-time world amateur champion, has not lost since 2012 and finished her amateur career 77-1.

RIO DE JANEIRO -- Its dynasty time on the opening two days of track and field at the Olympics.As of Friday morning, three athletes will each try to become the first woman to win three straight individual titles at the Summer Games.New Zealand shot putter Valerie Adams stands the best chance, while the odds dont look that great for 10,000-meter great Tirunesh Dibaba and 100-meter sprinter Shelly-Ann Fraser-Pryce. And if none of the three succeed, there still is Czech javelin double champion Barbora Spotakova on Aug. 18.Here is a look what opposition and odds they face Friday and Saturday:---VALERIE ADAMS/SHOT PUT -- She knows how to fight back. Two years ago, after being basically untouchable at major championships from 2007 to 2014, with four world and two Olympic gold medals to show for it, she underwent elbow and shoulder surgery. It is tough enough to return, but to come back with another Olympic gold would be outstanding.Recovery didnt come easy as the tall New Zealander struggled until early this year. Slowly though, she found her groove again and has championship experience. My preparations have been going really well, she said as she arrived in Brazil from her training base in Switzerland.Adams is the second-best performer of the season, behind Chinas Gong Lijiao. Christina Schwanitz of Germany, who took over Adams world title last year, could well be her toughest opponent on Friday.Adams knows how elusive Olympic gold can be. The London Games four years ago were already over when gold medalist Nadezhda Ostapchuk was caught for doping and Adams belatedly won her second title. This weekend, she wants to hold her third gold in the Olympic Stadium.---TIRUNESH DIBABA/10,000 -- Dibaba is already considered the greatest female distance runner in history with her five Olympic medals (threee gold) and five world championship golds.dddddddddddd. The 31-year-old has fought back from major injuries several times in her career and just finished a yearlong break after the birth of her son.Dibabas toughest opposition is likely to come from fellow Ethiopian Almaz Ayana, 24, who is doing the long-distance double in Rio after winning the 5,000 meters at the world championship last year and has the top 10,000-meter performance of the year so far.Dibaba is a massive celebrity in Ethiopia and leads a family of runners, including sisters Genzebe, who will compete in the 1,500 meters, and Ejegayehu, who won silver in the 10,000 meters in the 2004 Games.---SHELLY-ANN FRASER-PRYCE/100 -- For years, sprinting was a U.S.-Jamaican duel, but Fraser-Pryce will also have to keep an eye on Dutchwoman Dafne Schippers, who was already breathing down her neck when the Jamaican won her third world title in Beijing last year. And a toe injury has hampered Fraser-Pryce this year.Like Dibaba, she will need to heed her own compatriots. Eileen Thompson leads the charge with a seasons top time of 10.70 seconds. Three Americans have all run faster than Fraser-Pryce this season. None however, has proven it at major championships.Fraser-Pryce carried her nations flag at the opening ceremony, with her long hair dyed yellow and green, colors in both the Jamaican and Brazilian flags.---MEN -- Three men, all American, have won four individual golds in a row: Ray Ewry in the standing high and long jumps between 1900 and 1908; Al Oerter in the discus between 1956 and 1968; and Carl Lewis in the long jump between 1984 and 1996.---Follow Raf Casert on Twitter at http://twitter.com/rcasert ' ' '
