It's a guest-packed episode of The SIS Baseball Podcast as Mark Simon welcomed in Pirates coach and player development director Michael Chernow as well as three finalists for the SABR Analytics Conference Research Awards, Zach Crizer (The Bandwagon), Maddie Landis (Talk Sox), and Michael Rosen (FanGraphs). Michael Chernow explained how his job compares to that of a farm director, and shared how the Pirates organization works to build good habits in players and good habits in its coaches, such that both can get promoted to the major league staff or (in the case of coaches) pursue other areas within their baseball interest. Zach Crizer talked about his article for Opta Analyst, "Evolution in the Outfield: Is Center Fielder Morphing Into A Defensive Specialist Position" and cited the decline of center field OPS as players like Brenton Doyle, Kyle Isbel, and Tyrone Taylor become priorities for their teams. We also looked at his story from last season about right-handed batters and their lowered success vs left-handed pitching. Maddie Landis shared her article on "Baseball's Gatekept Pitching Metric: Inside Vertical Approach Angle" and explained what can be learned from knowing the angle at which a pitch crosses home plate. She also discussed what she wrote about baseball player success by shoe type and which hitters are primed for breakout seasons in 2026 based on a stat she created. Michael Rosen detailed what he learned from "How Much Do Trail Runners Matter? An Investigation" including which teams gained the most run expectancy from their successes. We also explored his articles on relief pitcher signings and also Wyatt Langford's defense. Thanks as always for listening.
