How often are the tennis stars on Hawk-Eye-
Challenges richtig?
Hawk-Eye has now become a permanent part of the game on the main courts at major tournaments. Players can challenge officials’ decisions and have them corrected when successful. A look at the success rates of the top players shows that not all players are equally successful with their challenges. Another technical aid to be used at the 2019 Australian Open is the shot clock. Prize money has also increased by ten percent.

Hawk-Eye success rates and favorites
The Hawk-Eye system was introduced in 2006 and has now become a permanent feature of professional tennis. Several cameras arranged at different angles can determine the position of the ball. Players can challenge the decisions of the chair and line judges. In addition to giving players the chance to correct a potentially wrong decision, the reviews also add an element of suspense for spectators. It is therefore interesting to see how often the Spieler richtig liegen. Since 2009 the ATP has kept statistics on Hawk-Eye challenges. The first interesting finding is that Roger Federer is wrong more often than his fiercest rivals — Novak Djokovic and Rafael Nadal. Accordingly, only exactly one third of Federer's challenges are correct. Spain's Nadal, at 34.4 per cent, does not fare much better. In Djokovic's case, at least 37.4 per cent of all challenges are right. Federer's chances of triumphing at the 2019 Australian Open should nevertheless have nothing to do with his Hawk-Eye success rate. According to Sportwetten According to Betfair, the Swiss is not the favourite to win in Australia. With odds of 2.37 (as of the end of October), Serbia’s Djokovic holds that role. Federer is second, closely followed by Nadal. Among the women, Serena Williams is unsurprisingly favourite. Germany’s Angelique Kerber has respectable chances at odds of 11.0 and ranks third with bookmakers behind Simona Halep. Federer was critical of the system when it was introduced; some joked that this was due to his poor odds.

Higher prize money and a shot clock at the Australian Open
Winning or losing a point can be decisive for the outcome of a set or match depending on the score and situation. A great deal of prize money is also at stake, especially at Grand Slam tournaments. At the Australian Open in January, this is ten percent higher than in Vorjahr. This raises the total to 37,39 million euros. The highest-paying tournament this year was the US Open, with the equivalent of more than 46 million euros. Another change is the so-called shot clock, used in all matches in Melbourne. It ensures that players take no more than 25 seconds between points before the next serve. This is intended to make the match faster and more attractive. There is also consideration of allowing coaching during matches in the future. For women, this is already permitted at all tournaments outside the Grand Slams.
