對，一般都說第一壘不要滑，但是:

As you run to base, your body's mass combined with your speed creates momentum, which changes into angular momentum as you slip into a slide, so the friction created with the ground doesn't slow you down as much as you might think. You may lose a little speed, but keeping your body stretched out may enable you to touch base sooner than if you kept running the whole way.

Before you get a brain cramp, here's how running can put you behind. If you stay on your feet, your momentum will try to keep powering you forward as you near the base, so you'll slow your speed to stay upright when you stop on base — adding time to your sprint.

• 這個就像Phelps在奧運會放棄最後一個stroke,改滑行，結果率先觸壁，打敗對手，奪金，願賭服輸唄。 -Francine- ♀ (0 bytes) () 10/30/2014 postreply 08:29:13
