Documents describing some of the original "Laws of Base Ball" sold for $3.26 million early Sunday morning, marking a new record for the highest-priced baseball document.

A spokesman from SCP Auctions said the buyer wished to remain anonymous.

The price paid is the third-most for a piece of sports memorabilia. SCP sold a 1920 Yankees' Babe Ruth jersey for $4.4 million in 2012, followed by the Naismith Rules of Basketball ($4.3 million).

The documents relate to the foundation of the game and include a document that first defined how the game was played in 1856.
