Who is best/worst at Challenges

[veran]

I'm curious since the introduction of the challenge system, who have you seen that consistently gets it right on challenges, and who is worst.

I read that one of the male players only got 4-17 on challenges at the US Open (don't recall the name) since 2006. That is really bad. Statistically you should in general be 50/50 on these calls, so whoever that player is he is really getting it wrong. I think Rafa is generally good on his challenges, slightly above 50/50. Federer has openly questioned the challenge system many times and is often on the wrong side of the result. Anyone keeps track of this?

serena...lol

I don't think I've ever seen Federer win a challenge! He always calls balls that are like 3 inches out at least.

 

[Cloudy]

Safin is not good at challenges

 

[jamesblakefan#1]

Murray isn't either. He challenges everything.

 

[alucard123]

Why does Federer hate the challenge system so much? He uses them for no reason sometimes

 

[jgreen06]

davenport is by far the best

federer won every challenge at the australian open 2007 semis and us open final.

Here's an article about Hawk-Eye's usage at the '06 Open:

From what ive seen:
Federer sucks at it. He's better off not challenging anything, though his challenges tend to be off by a fraction of an inch Murray has many bad calls as well.

Nadal's pretty good with challenges. Tipseravic is good too, since he tends to stare at the line for 20 whole seconds and comes up for a close up.
Nadal's pretty good.

 

[lovecr717]

djokovic and nadal are pretty good in challenging

That's not really true, because players challenge some calls even when they think they're correct but they have a very slight doubt. So it's not 50/50. Ljubicic used to win a lot of challenges (and matches too)

I'm talking statistically, since these are very close calls, if you randomly challenged, you are just as likely to get it wrong as you are to get it right, hence a 50% chance for the average person. If you are much better or worse than this percentage, then it is worth looking at and seeing why that is the case.

 

[scineram]

Wrong. They do not challenge randomly, so it depends on the player.

 

[ear_lobe]

Worst in Vince Spadea by far. Best is probably someone who doesn't challenge and gets it maybe a few times in a tournament.

 

[veran]

Wrong. They do not challenge randomly, so it depends on the player.

I didn't say anything about challenging randomly, this is purely a statistical term that says if you are the average person challenging calls, you should get it right 1/2 the time and wrong 1/2 the time. If there is a marked deviation from this, then it merits a look to see why.

 

[Dina Hamdan]

Well, I don't know he's the best or worst, but once I saw Jurgen Melzer playing maybe against Nadal, not sure, but Jurgen was winning every challenge, like he did 4 or more consequent true challenges...

 

[davidsmartin]

50-50 is an over-simplification since line judges get more than half the calls right and challenges are not random. Among the variables is who can make the better calls when it is close, the line judge or the player. If I were doing the challenging myself, I would be lucky to win much more than 10% of my challenges since I can never see the close ones (except on clay courts!) I am confident that many players have great eyes and when they have reasonable position can see the ball better than the players. And some players seem to challenge because they are mad at themselves for (barely) missing and need a minute to recover!

The deviation from 50/50 is what I'm interested in. If one person is markedly better than 50/50 or worse, then it says something about the way they challenge, as you've mentioned.

..

I remember Agassi having alot of successful challanges in his last U.S Opens.

 

[PROTENNIS63]

Fed used to be 100% accurate but that mono ruined his vision and now he is 70% wrong.

 

[Andres]

I once saw Safin trying to challenge an already-proven-wrong challenge

 

[tin]

the worst challenger is the one who doesn't ask his/her bench whether to challenge or not....=)

 

[FlamEnemY]

Janko Tipsarevic is the best there is

 

[veran]

Wow I wish there was a clip of that. Hilarious!

US OPen - Safin 1/12...that is hilarious.

Wow, guess he does get the crown. Djoker isn't much better...

Heh, it is about time.

Yeah, at Wimbledon this year Safin got the record for the worst challenge ever (seriously)

He challenged a serve that was 50 something centimetres in :shock:

 

[kelz]

Safin's challenge against Federer's second serve at Wimbledon this year. It was in by 50cm.

 

[tangerine]

Federer is the worst at challenges. :lol:

5-for-23
Roger Federer's success rate in video replay challenges, by far the worst percentage of any player in the tournament.

 

[pow]

Worst in Vince Spadea by far. Best is probably someone who doesn't challenge and gets it maybe a few times in a tournament.

I didn't know Vince Spadea was allowed on courts that had Hawkeye.

 

[Conquistador]

Worst: Bobby Ginepri--its soo funny when he pouts at the call

Both Spadea and Ginepri were 100% on their challenges at USO.

Andy Murray is one of the worst, getting only 3 of his 17 challenges correct. :lol:

^^^^ definately safin.

 

[superstition]

The Williams sisters tend to be good at it. I predict that Venus has the edge.
