Eno Sarris of The Athletic stops by to discuss his latest article that looks at the correlation between launch angle and strikeouts. He discusses the differences between practice testing vs live games, the dual importance of swing angle and plate discipline, the financial impact of the high home run/high strikeout era, and the potential future impact on the game as a whole. Greg and Josh also discuss the returning velocity of Aaron Sanchez, J.A. Happ's strikeout ways, Curtis Granderson turning back the clock, a couple of performing rookies, and the latest update on Troy Tulowitzki's health and what it means for the roster. Finally, they answer listener questions and look at Gregg Olson's written-down "unwritten" rules of the game.
