This week, I conclude my recent rundown of notable developments at the full-season affiliates in the A's system. In the first half of the show, I examine the factors that led to Jonny Butler's June breakout that saw him recently promoted to Midland, then look at five talented Lansing players looking to follow suit and conquer the High-A level more fully. In the second half, I turn to the complicated issue of analyzing the position players at Triple-A Las Vegas in a way that removes the inflation provided by the Aviators' extremely hitter-friendly home park and the Pacific Coast League as a whole. I go into detail about the exit velocities and swinging strike rates of every player on the Las Vegas roster and how they compare to those of the players above them in Oakland, before turning to more detailed breakdowns of the team's top prospects both in the field and on the mound.
