This weekend’s Pennsylvania Derby is the focus of the Ron Flatter Racing Pod. Trainer Bret Calhoun discusses his four-time graded-stakes winner Mr. Money, a contender to win Saturday’s feature. Longtime Philadelphia sports writer Dick Jerardi handicaps the fields for both the Penn Derby and the Cotillion Stakes. Twitter feedback reacts to last week’s big stories about Justify’s positive drug test and the end of racing futures in Nevada. The Ron Flatter Racing Pod is available via Apple, Google, Stitcher and at VSiN.com/podcasts.
