What does the baseball term "Golden Sombrero" mean?

The game of baseball is full of terms. A "golden sombrero" is a player's inglorious feat of striking out four times in a single game.

For those not familiar with the game of baseball here is an explanation of the term " striking out".

A batter steps into a batting zone either to the left or right of a marker called "the plate". A pitched ball is ruled a ball by the umpire if the batter did not swing at it and, in that umpire's judgement, it does not pass through the strike zone. Any pitch at which the batter swings unsuccessfully or, that in that umpire's judgement passes through the strike zone, is ruled a strike. Each ball and strike affects the count, which is incremented for each pitched ball with the exception of a foul ball on any count with two strikes. That is, a third strike may only occur by the batter swinging and missing at a pitched ball, or the pitched ball being ruled a strike by the umpire with no swing by the batter. A pitched ball that is struck by the batter with the bat on any count, and is not a foul ball or foul tip, is in play. A batter may also strike out by bunting if the ball is hit into foul territory. Three strikes is an out and is called "striking out." Four balls is a walk and the batter walks to first base.

The term was coined by San Diego Padres player Carmelo Martínez in the 1980s and first appeared in print when Leon Durham was quoted as using it in 1984.
