无论你有没有打过高尔夫,想必你都听说过这个词:标准杆。标准杆的意义并不在于它能直接决定一场比赛的胜负,可它简化了比较各个参赛选手的实力和发挥水平的办法。那么,网球有没有这样的标准杆呢?答案是有的,至少在硬地球场上,我们找到了属于网球的标准杆——二发得分率。也就是说,下次你要想再简单点比较运动员的实力或者近期水平的发挥状况,只需看看他们的二发得分率就可以了。对本届美网官方所提供近200场(男女均包括)数据进行了统计汇总后,经过分析发现,在各项统计数据中,二发得分率与一场比赛胜负的关系有着最为紧密的联系。结果如下:男子方面,如果某位选手的二发得分率达到50%以上,那么数据显示,他赢得这场比赛的概率将超过75%。要再通俗一点, Whether you have played golf or not, you’ve probably heard the word: par.
