Don't know the rules of baseball, then? The hitter probably had two strikes and then fouled off a couple of times while avoiding the third strike and accumulating four balls, which allowed him to walk to first.
Totally weird if you don't understand it, much like suddenly landing in, say, Thailand and being subjected to all that totally weird gibberish all over the place. Right?
As for stats, the American fascination with such has always amused me, but I see now soccer (and don't get me started on the canard that "soccer" is an Americanism) is just about as bad.
