The bottom line for there being more no hitters is that over the last 10 to 15 years, batting averages are down.

没有击球手的原因是，在过去的 10 到 15 年里，击球率下降了。

The pitchers don't go and throw a complete game nearly as much as they did so you're seeing a lot more combined no hitters.

投手不会像他们那样去投一场完整的比赛，所以你会看到更多的无击球手组合。
