Pete Rose played for the Cincinnati Reds way back in the '70s and '80s. He was probably best known for his head-first slides. He had a .303 batting average and holds multiple Major League Baseball awards.
The S.O. plays recreational softball. He has not learned the art of the head-first slide.
The photograph to the right shows Rose executing a picture-perfect head-first slide.
The photograph below shows what happens to your hand when you attempt a head-first slide and you're not a 17-time MLB All-Star.
The finger is broken "in several places" and will require a specialist. On the upside, the S.O.'s team won the game.
It's a very small upside, in my opinion.
