Kevin Towers made it a priority to add depth to the Diamondbacks' minor league system when he arrived in late 2010 and he has. The infusion of young talent should help the D-backs make the trade of their choosing this winter.

The system is especially rich in starting pitching prospects and in capable shortstops which many consider the two most desirable market commodities. Add in a couple of third basemen and a couple more hard-throwing relievers and there is ample quality.

While it takes two to make a deal the Diamondbacks could use their young talent as a way to either land a bigger fish or as options to plug holes if a veteran is moved. It is a comfortable place to be.

Some of the up-and-comers will be harder to reach than others. Top right-hander Archie Bradley for example is not going anywhere. Bradley who just turned 21 in August was the D-backs' minor league pitcher of the year and many scouts believe he can be a top-of-the-rotation starter in the major leagues.
