The first clearly documented match between two baseball clubs under these rules took place on June 19, 1846, at Elysian Fields in Hoboken, New Jersey. In this match, the Knickerbockers lost to the "New York nine" (probably the parent Gotham Club) by a score of 23 to 1. Some authors have also questioned the supposed "first game" under the new rules. The Knickerbockers' scorebook shows intra-club games during 1845; the New York Base Ball Club played at least three games against a Brooklyn club in 1845 also, but the rules used are unknown. Those who have studied the score-book have concluded that the differences in the games of 1845 and 1846, compared with the specifications of the Knickerbocker rules, are minimal.
