Correct.

ATP has a radar system they use for major events, allowing them to go back and replay a shot in dispute...

The reason they have a limited allowed number of "challenges" - or complaints if you will - per player is to save time.

Between 10 and 20% of the challenges turn out in favor of the challenging player, most of them by far prove a correct umpire decision.

What another glorious day in the history of one of the least competitive major sporting events around today. Managed to miss it all and won't be going on the BBC website to see Roger's crocodile tears either (he surely must have burst into tears did he?) *rolls eyes*. Oh well, hopefully in the next cycle of grass court tennis we won't see domination like that of Sampras and Federer and maybe some feel-good stories will come out of Wimbledon for a change (the last one was Ivanisevic), that is after all what sport is all about

Don't think Roger burst into tears I think he was feeling a lot of sympathy for Roddick - after all, most people do.

Hopefully over the next year or two other players start to really challenge Federer and Nadal - good possibilities being Murray, Djokovic, Wawrinka, Soderling, Roddick, Hewitt, maybe even Haas and Karlovic.

Karlovic is a joke. Never seen such a poor tennis player once he has his serve returned.

Ermm, what about Cilic Mr Yoda? Sure Cilic will be up there soon.

But farcical ain't it, Roddick wins more games, yet loses 16-14 in the final set.

Breaks: 2-1 to Roddick
Games: 29-28 to Roddick
Sets: 3-2 to Federer

Cilic as well Warns

That's always been the case though. It's only because it's a final they've suddenly came out with that statement.

I think the current system is good enough. It is very sad to see Roddick being broken once, which ended up as the winning game, but that's what happens.

I'm no tennis fan Yoda but the guys that you've mentioned as competition to Federer have already been around for a few years so I can't see them breaking Federer's domination of Wimbledon any time soon.

What I meant by the next cycle, is the next generation of players after Federer retires, so I'm guessing these players are currently competing in the boys singles I just hope that 4 or 5 players come through who are all capable of beating each other on their day so it becomes exciting to follow

Djokovic, Murray and Nadal are only somet like 22/23 compared to Federer who is 28.

So they all have 6 years on him, Nadal and Roddick took Federer to 5 sets in last two Wimbledons, so no competition? Nadal beat him as well last year.

Federer only claimed his FIRST French this year, so total dominance and no competition, you sure Walker?

Yes I'm sure

Also, Nadal AND Murray have better head-to-head records to Federer when they play him

Out of interest how many sets had Federer lost in the rounds leading up to the final this year?

How many sets has he lost in the last 7 years at Wimbledon?

Three players at the top doesn't make a sport competitive (and even Murray has won next to nothing), no matter how you want to sugar coat it.

Hendry dominated snooker in the 90's which spoiled things for me as a viewer growing up interested in snooker. And even though he won the world championship a string of times he was still getting beaten in the UK championship, B & H Masters etc. and yet he was still viewed as the dominant force. So, just because Federer has poorer head to head records versus Nadal and Murray doesn't mean much if he's winning the tournaments that really matter.

I'm off out now, will argue later

So what? sets win matches, matches win the championship..Roddick was 6-2 up in the 2nd set tie-break and lost 6 points in a row...as much as i hate to say it...the chaps an absolute bottler!

2003: Federer (1 set to Fish (R3)) = 1
2004: Federer (1 to Hewitt (QF), 1 to Roddick (F)) = 2
2005: 1 to Kiefer (R3) = 1
2006: 1 to Nadal (F) = 1
2007: 1 to Ferrero (QF), 2 to Nadal (F) = 3
2008: 3 to Nadal (F) = 3
2009: 1 to Kohlschreiber (R3), 2 to Roddick (F) = 3

Overall sets lost: 14

Didn't win the title in 2008. And if he was soooooo dominate in every major tennis tournament, how come he wasn't number 1 until he won this year's Wimbledon?

Federer doesn't dominate every tournament, but he dominates Wimbledon which is the topic of the thread and to what I was referring to. On a broader scale mens tennis is dominated by two people, unfortunately each of these guys has a preferred surface and dominates on that surface. Therefore for any given tournament one of the two will be massive favourite to win. As there is a long clay court season, Nadal has more tournaments from which to win points (although he also has to defend them in subsequent seasons which can be a disadvantage). Ranking systems in general are prone to anomalies anyway so not much should be read into them.

The system for the challenges should be used for the likes of football.

Hawk-Eye is coming into football, challenges is in some forms of cricket when appeals of OUT.

Unsure how that can be further used in football to be honest. Hawk-Eye will give the referee a bleep for whether the ball goes over the goal line for a goal to count

It would be good to challenge the awarding of certain free-kicks in football. For instance, if somebody has blatantly dived to win a free kick or is holding their face pretending they have been elbowed, everything can be cleared up using video evidence. It would inevitably stop so much cheating in the game. I don't think it would slow the game down that much either, as alot of the time the game is stopped for a bit so that the physio can come on. The main problem is that you could probably only use video evidence in the top division for financial reasons. In the lower leagues you may be able to get away with diving more, but since there are less foreigners in these divisions, there isn't as big a problem with cheats (probably).

And not out it wont be put in place for the Ashes tho.

I'd love it if video evidence arrived in Scotland. Some of the cheating in the SPL is abysmal at times, I've watched St Mirren been done over by poor refereeing decisions time and time again against Celtic especially. The only problem we'd have would be the referees not wanting to deny Celtic their opportunities, as they seem very happy to always help them.

No matter what, video evidence does need introduced. For problems like the Zidane headbutt, and the Egypt handball against Brazil in the confeds cup when the Egypt player pretended to have cracked his head off the post, proves how useful it can really be.

Hawk eye has been a great success in tennis, it can work in other sports.

this is my first post here but i always want murray to win wimbledon and i know he can do it so go murray!!!
