Who is Billy Meyer? His may be baseball's most mysterious retired number. Join Zach and Leo as they also banter about Danny Murtaugh, Pie Traynor, Ralph Kiner, and Bill Mazeroski.

Nolan Ryan, Bill Wagner, and the Killer Bs give us more than enough to talk about. This episode is long but is rich with fun baseball trivia and banter.

Neither Roy Oswalt nor Lance Berkman have their numbers retired, but the Astros have no shortage of players to whom they've given the honor. Zach and Leo discuss six players all of whom they, more or less, just learned existed (Jim Umbricht, Don Wilson, Mike Scott, Larry Dierker, Jimmy Wynn, and Jose Cruz).

Zach and Leo discuss four Cleveland greats, including recent-ish star Jim Thome, and three players (Doby, Boudreau, and Feller) whose greatness aligned to bring about Cleveland's most recent world series title (1948).

If you aren't a Guardians fan you probably haven't heard of Earl Averill, Mel Harder, or Bob Lemon. You also may wonder why Cleveland has retired the number of Orioles and Reds legend Frank Robinson.

Who is the most iconic Minnesota Twin? It's a four-horse race between Joe Mauer, Kirby Puckett, Rod Carew, and Harmon Killibrew. Zach and Leo break down the numbers and lore behind these four Hall of Famers.

Long-reigning manager Tom Kelly, homegrown first baseman Kent Hrbek, and three hall of famers who had to fight for recognition (Tony Oliva, Jim Kaat, and Bert Blyleven) are the subject of today's episode.

Zach and Leo discuss the Oakland Athletics' ownership history, including the legacy of retired "number" holder Walter Haas Jr. Then they move on to two of baseball's biggest personalities: Reggie Jackson and Rickey Henderson.
