RIO DE JANEIRO -- Its match point at the Copacabana beach volleyball venue, and a spike catches the line for the winning point.Or does it?While one side celebrates an apparent victory, the would-be losers turn to the first referee and form a C with their fingers to challenge whether the ball was in or out. The ref signals to the replay booth by tracing out a TV screen with his index fingers and everyone -- the players, the fans, the viewers at home -- waits for the result.The Olympics are using a replay system in volleyball and beach volleyball for the first time in Rio de Janeiro, and so far it has accomplished the goal of cleaning up calls that have the potential to influence the outcome of a match.We want the game to be more transparent, said Angelo Squeo, the director of beach volleyball for the international federation. We want the players to be happy with the decisions. We want the game to reflect what happens on the field of play.Although in use for a couple of years in indoor volleyball, the challenge system was first brought to the beach at the Rio de Janeiro test event last year. This is the sixth FIVB beach event with the Hawkeye system, the same one used at major tennis tournaments.I cannot imagine now for a moment going back, Squeo said on Monday. For sure, players are happy, spectators are happy, because the match doesnt end on a mistake. Its an essential device.While replay challenges have been known to slow other sports to a crawl -- imagine a major league baseball manager on the top step of the dugout, waiting for the signal from his video people -- volleyball seems to have it under control, for now.Teams get two unsuccessful challenges per match. They have five seconds to challenge, and only a handful of line and net calls are eligible. (Notably excluded are judgment calls, like whether a player has lifted or double-hit the ball on a set.) The decision is made by an official with a monitor in a booth behind the players benches.We think its great, Dutch player Madelein Meppelink said after beating Costa Rica 21-16, 21-16 on Monday to improve to 2-0 in pool play. For the referee, its hard to see everything.Squeo said about 25 percent of calls are overturned; the average time for a review is about 30 seconds. While they wait, the fans at the indoor volleyball in Maracanazinho arena chant and clap in unison and then cheer or boo the decisions.Meppelink said her only complaint is that the system could go even faster. But there also have been a couple of times where the replay took some of the excitement out of a finish.On the first day, China called for a review on a net fault on a match point against Switzerland in the third set and appeared to win the challenge. The Chinese women celebrated and took the microphone to thank the crowd, but the Swiss continued to argue with first referee Lucie Guillemette.After several minutes, the officials called everyone back to the court and resumed play because the Chinese had finished out the point instead of stopping play to challenge the call immediately.I didnt think she (the referee) was going to listen to us, but we knew we were super-right because it had happened to them before, said Switzerlands Isabelle Forrer, who lost the match to China anyway a couple of points later.When Casey Patterson and Jake Gibb played Austria on Monday, Gibb hit the net on the final point, a spike that went out and otherwise would have kept the Americans alive. Gibb appealed to the referee that the ball had hit the sand before he faulted, to no avail.Thats just us not giving up, Patterson said after the 21-18, 21-18 dropped them to 1-1 in pool play.Patterson hasnt had the opportunity to use the challenge system yet, because its only been at a half-dozen events, and even then only on the championship court thats wired for it. Those are usually reserved for the hometown favorites and other marquee teams.Squeo said the FIVB plans to expand the system to a dozen or more of the top-tier events next year. It costs about $30,000 per tournament to have the system, and the FIVB is looking for a sponsor to pay for it.But they wont be able to do what Meppelink wants: go back in time and fix some of the calls that went against her in the past.I can think of points that I wished we had the challenge system, she said.---AP Sports Writers Janie McCauley and AP Tennis Writer Howard Fendrich contributed to this story.---Jimmy Golen also covered beach volleyball in Beijing and London.

Adam Vinatieri Jersey .ca looks back at the stories and moments that made the year memorable.Jonny Bairstow reveals which caped hero he would dress up as, plus reflects on Englands Headingley victory, his second Test ton and Leeds Rhinos struggles… Headingley was a great Test match for myself and the team - and I also had a lot of fun chuckling at the crowd!There were loads of people in fancy dress - I saw foxes, plus Zippy from Rainbow and much, much more, and it just goes to show how great a place Headingley is to play and watch cricket. Jonny says he fancies dressing up as Robin If I attended I would probably come as Ron Weasley from Harry Potter - I have the hair for it - but having been to university I am no stranger to fancy dress, while I have pretended to be Batmans sidekick Robin in the past.Liam Plunkett would probably be my Batman - thats who he turned up as at a Yorkshire end-of-season do and as he is a bit taller than me we would probably look the part.Im sure there will be plenty of fancy dress up at Durham, too, with it being Bank Holiday Weekend, and I expect there will be people wanting to outdo the Yorkshire folk in those stakes. Im sure the Durham fans will be disappointed that Ben Stokes is out injured and so are we - we know the qualities he possesses in all departments.Hes our fourth seamer, a destructive batsman at No 6, and is superb fielding either in the slips or in the outfield, so it will be a big loss.Stokesy, too, will be frustrated that he wont be out there - thats the sort of competitor he is - but as he has two kids Im sure he will be kept pretty busy!We wish him a really speedy recovery, and we know that whoever comes in will do a sterling job. Jonny Bairstow’s return to the England team came about in the fifth ODI against New Zealand last summer SpecialI now have two Test centuries to my name after my 140 at Headingley, and although they have come in completely different scenarios, both were very special.The first one, my 150 not out against South Africa in Cape Town, was huge because it was my first in an England shirt but the second was big, too, as it was on my home ground with the side in a more difficult position.I didnt tell myself too much when I came in at 83-5 - you dont want to change too much about the way you have been playing so I didnt consciously adapt anything. Bob Willis and The Verdict panel praise Jonny Bairstow’s hundred against Sri Lanka at Headingley and look at the strides he has made since his early Tests I was slightly nervous in the nineties - if youre not in that situation then I think theres something wrong with you - but thankfully I was able get over the line.ddddddddddddI enjoyed my partnership with Alex Hales - the runs he scored and the length of time he batted was imperative for us as we set a total that helped us win the game.Steven Finn played his part, too - his flick for four off sixth stump was an epic shot! He was delighted and we had a real laugh about it, but we quickly told him to get back in his box! Steven Finn, perhaps surprisingly, played some glorious shots at Headingley TurnaroundI didnt get to see much of Magic Weekend with the Test overlapping with it but it was obviously disappointing to see my side, Leeds, beaten by Wigan.Its been a real tough start for the team and they are currently bottom of the table, but they are a tough unit and have a brilliant fan base which will stand them in good stead.We must not forget that they won the Super League and Challenge Cup double last season and that over a long period of time the club has achieved a huge amount of success. Highlights from the Magic Weekend match between Leeds and Wigan The quality in the side is unbelievable and it will only take one or two games and for one or two things to go their way and then they will be on a roll - thats the nature of sport.Its like my golf game - Im hitting it really well at the minute but no doubt it wont be too long before it turns around and I am playing a few more shots than I would like!Watch live coverage of Englands second Test with Sri Lanka, from 10am, Friday, Sky Sports 2.
