On this episode of the SI Media Podcast, host Richard Deitsch interviews pair of guests: Yahoo Sports MLB columnist Jeff Passan, the author of "The Arm: Inside the Billion-Dollar Mystery of the Most Valuable Commodity in Sports," and The New York Times horse racing writer Joe Drape, the author of "American Pharoah: The Untold Story of the Triple Crown Winner’s Legendary Rise."

Passan discusses how why he wrote the book, how to get year-long access to subjects, what it was like interviewing Sandy Koufax, the most interesting single story in baseball this year, why Barry Bonds and Roger Clemens should be in the Hall of Fame and more.

Drape discuses why we should still care about American Pharoah, his experience inside a thoroughbred breeding shed, the personalities of trainer Bob Baffert and owner Ahmed Zayat, the favorites for the 2016 Kentucky Derby and more.
