The Giants' ability to produce impact players from within has been central to their impressive success in recent years. The evolution of the Brandons from solid regulars to stars, and the development of another not very widely heralded prospect, Joe Panik, into a very solid starter are the most recent examples of this. The Giants have also gotten a bit lucky with their farm system. For example, although it is unlikely to look this way at the end of the season, Matt Duffy, a player about whom a year ago all but the most intense Giants fans had heard nothing, is quietly having a better year (.279/.324/.388) than the major star, Pablo Sandoval (.251/.317/.371), who he replaced. In an era that is more competitive, with more teams, and more safeguards against dominance by wealthier teams, the Giants continue ability to produce quality players from within is an extraordinary accomplishment and one that goes a long way towards explaining those three rings.
