Opening week at Saratoga is the focus of the Ron Flatter Racing Pod. Saturday's Grade 1 Diana Stakes features a showdown between defending winner Sistercharlie and her stable mate Rushing Fall, whose owner Bob Edwards discusses her near perfect career. Horseplayer and author Peter Thomas Fornatale talks about the year in racing and the evolution of some of his betting angles. The Diana gets a full preview, and there is Twitter feedback to be sampled. The Ron Flatter Racing Pod is available via Apple, Google, Stitcher and at VSiN.com/podcasts.
