The 1910 Chicago Leland Giants were really the predecessors of the American Giants (a name they would adopt the next season), Rube Foster having wrested legal control of the name from the former owner, Frank Leland.  It is commonly reported that Foster considered this team his greatest (or possibly the greatest of all time), and that the team finished with 123 wins and only six losses for the season. 

But when the Lelands visited Cuba that fall, Almendares alone beat them six times (losing twice, with one tie).  Here are the statistics for the series:

John Holway’s Complete Book omits this series entirely.  Figueredo’s Cuban Baseball lists ten games, while I’ve been able to find 13.  Figueredo lists one game I haven’t found yet, so there’s probably a total of at least 14 games.

Here’s where what I found differs from Figueredo:

October 16: Leland Giants 7, Almendares 0.  Figueredo incorrectly lists it as a victory over Habana.

October 21 or 22 (assuming Figueredo’s scores are in correct order): Almendares 3, Leland Giants 1, with Pedroso defeating Bill Lindsay.  I haven’t found it yet.

And Figueredo misses these games:

October 30:  Leland Giants 7, Almendares 6.

November 6: A doubleheader, with the Lelands beating Habana 6-1 in the first game, then losing to Almendares 1-0 in the second.

November 7: Almendares 4, Leland Giants 3.
