Where did the baseball term 'around the horn' come from?

In Baseball terminology, an "around-the-horn" double play occurs when the third baseman fields a ground ball and throws it to second for an out. The ball is then relayed by a middle infielder to first base for the second out. Since it is the longest way to make a double play, the term is derived from the nautical route from England to India via the horn of Africa.
