Our good friend Harry Pavlidis of Baseball Prospectus joins the show to share the latest on pitch tunnels, why we will see more breaking pitches in 2018, and breakdown PECOTA's 2018 projection for the White Sox. Harry will also give a reason why the White Sox could be a .500 team, and why the White Sox could have a worse record than last year.  In the end, we answer your questions in P.O. Sox.
