during the 86th MLB All-Star Game at the Great American Ball Park on July 14, 2015 in Cincinnati, Ohio.

MLB Network suddenly announced a third new edition of MLB Network Presents this week, featuring a roundtable discussion with the Franchise Four Greatest Living Players, as announced prior to the All-Star Game on Tuesday.

Bob Costas sat down with Hank Aaron, Johnny Bench, Sandy Koufax, and Willie Mays to talk about their careers, each other, and some of their most memorable moments.

This looks pretty fantastic, and isn’t a situation that pops up every day. How often do you get four of the greatest athletes ever in *any* sport in the same room for a discussion?

Koufax’s inclusion is noteworthy, because while Aaron, Bench, and Mays have made their share of public appearances, Koufax doesn’t exactly seek out the spotlight and give many interviews.

The episode will be preceded by Randy Johnson, The Big Picture, which focuses on the 2015 Baseball Hall of Fame inductee.
