I don't know if it was broadcast nationally, but there was an interesting feature on KPCC a day or two ago, about the future of the head-first slide in baseball.
It seems the Major leagues is looking into discouraging the practice, as it has the potential for season-ending injuries. The most common such injury is jammed fingers (owww!), but of course the player's eyes, nose, teeth, mandibles and orbitals are seriously imperiled when he hurls himself face first at the bag.
So why do they still do it? This was the question the reporters asked some guys who were running a youth baseball camp which had workshops on the face-first slide. The answer they gave seemed to keep with the notion that baseball is a metaphor for life: If you want something bad enough: Dive for it! If your finger gets busted along the way - so be it.
The guys who were giving the baserunning seminar where quick to point out that they are not neccesarily encouraging the head-first slide for the kids in the camp. Instead they want to teach them how to go about it safely (or at least the safest way possible). It was stressed that the most important factor in succesfully sliding face-first into the bag is confidence. The feet-first slide they pointed out, can oftentimes be adequate, but sometimes you have to be a little hungrier.

But on a more fundamental level, the trainer pointed out, the head first slide represents the true spirit of a champion. He mentioned players like Pete Rose and Len Dykstra; guys who weren't neccesarily born gifted with a graceful, athletic body. They're the guys who made the head-first slide famous, because they will put nothing ahead of scoring the run, and winning the game. These are the players who make up for their natural shortcomings with pure ferocity and will.
As far as Pete Rose goes, I always though *charlie hustle* was the best nickname in the history of baseball - and I still think basebal, above all other professional sports, manages to come up with the best nicknames. From "the bambino" to the "big unit", baseball players are the most folkloric figures in sport.

The guy who will risk broken bones in order to steal a base, according to the camp trainers, is the guy you want on your side.
