Newly elected Hall of Famer Joe Mauer was the first-ever No. 1 prospect when MLB.com started rankings back in 2004. On this week's edition of the MLB Pipeline Podcast, Jim Callis, Jonathan Mayo and Jason Ratliff take a look at Mauer and the other 'greatest hits' from 20 years of rankings, while also looking at guys who were top prospects who didn't quite live up to billing. The guys are then joined by former long-time Twins general manager Terry Ryan for a look back at how Minnesota decided to draft Mauer No. 1 overall in 2001. Then talk turns to the others in this year's Cooperstown class, Todd Helton and Adrian Beltre, before the trio discusses recent trades involving Top 100 prospects Joey Ortiz and Gabriel Gonzalez and finishes up with a question from the Mailbag.
