A Hall of Fame trainer and a television icon are the guests on the Ron Flatter Racing Pod. Bill Mott helps preview Saturday’s Fountain of Youth Stakes, where his impressive maiden winner Hidden Scroll is expected to be the favorite. Former horse breeder and “Tonight Show” bandleader Doc Severinsen talks about his longtime love of horses and the Kentucky Derby winner that he could have owned – but he let it get away. The Racehorses by the Letters feature looks at the best horse starting with the letter “Q,” and Twitter feedback gets a reading, and a commentary is offered on the recent fatal injuries at Santa Anita. The Ron Flatter Racing Pod is available at Apple, Google Play, Stitcher and VSiN.com/podcasts.
