We're back! After a holiday hiatus, the PDP returns with Baseball Prospectus swing guru Ryan Parker. We'll discuss what makes Raimel Tapia such an elite offensive prospect, David Dahl's continued development and return from injury, Class A second baseman and Tyler man crush Forrest Wall, the problem with hitting at Coors Field, and much more.

Plus the Rockies make a push to get Troy Tulowitzki to the All-Star Game in Cincinnati. You enraged local media members with your willingness to vote on Twitter, so that makes us happy. Finally, we'll chat about Nick Groke's latest story on the team's feelings regarding Jon Gray still kicking around Triple-A.
