We're taking a trip in the wayback machine on this week's episode of the Purple Dinosaur Podcast.

Matthew Repplinger, president of the Rocky Mountain chapter of the Society for American Baseball Research (SABR) joins the show. We'll talk Denver baseball history, from the origins of the sport around the Mile High City to the Denver Post tournament glory days between the world wars and up to SABR's mission to mark home plate from Bears Stadium at Sports Authority Field at Mile High (which Tyler calls "Invesco Field at Mile High" in this episode because corporate naming rights are stupid.)

Plus, we chat about the similarities between the Rockies and Royals with Mike Vamosi of KingsofKauffman.com, from the difficulties of graduating top prospects, frugal ownership, and more.

We'll also discuss the Rockies' impending rotation decision on a struggling Franklin Morales, but that's depressing. Do with it what you will. Download and subscribe on iTunes and Stitcher, and tune in on PurpleRow.com!
