Djokovic's break points problem
Throughout Novak Djokovic's career, what has made the Serb so successful has been his ability to raise his level on the most important points. However, starting with his quarterfinal against Rafael Nadal in Rome, Djokovic has had to find a way to win without winning a high percentage of break points.
This problem doesn't apply to just break points on return, but also on serve, meaning Djokovic is neither saving nor converting break points at a high rate.
In his career, Djokovic saves about 65% of all break points he faces, which is almost equal to his rate of winning non-break points on serve (67%). However, in his last seven matches, Djokovic has only saved 52.5% of all break points he has faced, which is drastically lower than how well he is doing on non-break points.
Djokovic is facing a similar problem with his return. In his career, he has converted 45% of all break points he has faced and in 2011, he won 49% of break points on hard courts. Even in 2009, which was Djokovic's worst year, he was winning 42% of break points. Yet since his match with Nadal at Rome, Djokovic has only converted 36% of break points.
Earlier this year, Djokovic won 17 of all 21 break points against Dominic Thiem to win 6-3, 6-4 despite being thoroughly outplayed on non-break points. There is a chance Thiem will play Djokovic in the semifinals and if Djokovic does not raise his level on break points, he will have no chance against the Austrian.
The way the Serb has been able to survive so far is that he is producing far more break opportunities on his return than he is facing on his serve. However, continuing to do that will become significantly more difficult in the later rounds of Roland Garros as the level of his opponents rises. In order for Djokovic to win the only major that he is lacking is to improve his level of play on the break points, which seems to be the only hole in his game of late.

诺瓦克·德约科维奇的破发问题
在诺瓦克·德约科维奇的职业生涯中，一直以来是他提升对关键分把握的能力使这位塞尔维亚人获得了成功。然而，自从在罗马面对拉斐尔·纳达尔的四分之一决赛开始，德约科维奇需要找到在没有高破发率的情况下获胜的方法。
这个问题不仅表现在破发回球上，还有发球，这意味着德约科维奇不能高效的挽救以及转化破发点。
在职业生涯中，德约科维奇挽救了大约65%他所面对的破发点，这与他在非破发点的得分率（67%）差不多。然而在过去的七场比赛中，德约科维奇只挽救了52.5%他遭遇的破发点，这大大的低于他在非破发点上的得分。
德约科维奇在回球上也遭遇了相似的问题。在职业生涯中，他转化了45%手握的破发点，2011年他在硬地的破发得分达到了49%。即使是在德约科维奇表现最糟糕的2009年，他在破发点的得分也有42%。但是自从他在罗马和纳达尔的比赛开始，德约科维奇对破发点的转换率仅有36%。
今年早些时候，德约科维奇在与多米尼克·蒂姆的比赛中赢得了21个破发点得分中的17个，从而以6-3/6-4赢得了比赛，尽管他在非破发得分上被对方击败了。在半决赛中德约科维奇可能会遭遇蒂姆，假如德约科维奇无法提升他在破发点上的表现，面对奥地利人时他可能会失去机会。
塞尔维亚人能够打到现在的方法是在回球中创造出比发球局更多的破发机会。但是在罗兰加洛斯的往后几轮当对手实力增强时，继续这样做回变得困难。为了赢得唯一缺少的大满贯，德约科维奇需要提高他的破发点得分能力，这看起来是他在比赛后程唯一的缺陷。
