1854 Unified Knickerbocker-Eagle-Gotham Rules
In November 1853 the Eagle Club sent a letter to the Knickerbockers, asking for guidance in the rules of the game. The result was a three-way conference the following spring at Smith's Tavern between representatives of the Eagles, Knickerbockers and Gothams, where they agreed upon a joint set of rules for all three clubs. It will be seen that in most respects they duplicate the Knickerbocker gameplay rules, but with three key additions: the first ever specification of the pitching distance in Rule 1, the first rule governing the size and weight of the ball in Rule 17, and Rule 8 which established the modern force-out: under the original 1845 KR, a baserunner could be put out by touching the base ahead of him whether he was forced or not; the 1848 revision restricted this to first base only and (by implication) required a tag at any other base.
Adopted April 1, 1854
1st. The bases shall be from “Home” to second base, forty-two paces; and from first to third base, forty-two paces, equidistant; and from Home to pitcher not less than fifteen paces.

6th. A ball being struck, or tipped, and caught, either flying or on the first bound, is a hand out.

8th. Players must make the bases in the order of striking, and when a fair ball is struck and the striker not put out, the first base must be vacated as well as the next base or bases if similarly occupied; players may be put out, under these circumstances, in the same manner as when running to the first base.
