Last Friday, at an airplane hangar turned into a pitching lab somewhere in Arizona, the Cubs’ most modern pitching prospect did the thing that modern pitching prospects do: he PR’d. Max Bain, who has been a member of the Cubs organization for 14 healthy months without logging a professional inning, hit 98.8 mph on a Rapsodo. Bain, who works as a pitching trainer at former Cub Luke Hagerty’s X2 Athletics facility in Scottsdale, is the walking definition of a prospect in 2021. The 23-year-old righty is the guy other prospects trust for pitch design advice. His weekly live AB’s are more focused on the tunneling and the design of his four secondaries than the number on the radar gun. He weaves seam-shifted wake and vertical approach angle into casual conversation. He’s vlogging the journey on YouTube.
