Getting hit in the face/neck by a cricket ball moving at 150mph can cause serious injuries, even death.

Minor nit: Fastest ever recorded ball bowled was 100 mph. I believe you were thinking 150 kmph.

Also, if we're talking about street/amateur cricket, or even higher-level cricket a couple of levels removed from international, you are rarely going to have rockets hurled at you. Most will be 120 kmph tops.
