Today, Edwin Escobar will become the 100th starting pitcher used by the Diamondbacks. But even among the hardcore fans here, many people are asking, who is this guy? The pitchers who get promoted from Triple-A to fill rotation spots for the Diamondbacks usually fall into two categories: rising young prospects whom we've been following through the farm system, or experienced veterans who have had a significant track record over their careers. Escobar is neither: Just 22 years old, he was originally a Rangers signing out of Venezuela in 2008, only joined the D-backs last month, and has two innings of major-league experience.
