Unfortunately there are a several date errors in the Boomtown Sport article. It contains some good research, so the date errors are a pity.
In one case, the article states that the Earps left San Diego and relocated to San Francisco in 1891.

I have no doubt that Earp and Rickabaugh were in San Francisco by November-December of 1892 to see the horse, "Lottie Mills," win 4 consecutive races. These wins prompted the duo to then purchase the horse, and on December 10, 1892 the filly won its first race for Earp & Rickabaugh in San Francisco. According to Boomtown Sport, Wyatt was then listed in the 1893 San Francisco City Directory.
None of this assists with the original question, but it does prompt a warning about some dates in the Boomtown Sport article. (other date problems relate to the Idaho and section.)
