His obituary in Sporting Life called him "Anson's Understudy", saying that he was an all-around player who played both in the infield and outfield and finally succeeded Anson at first base. He died after several years in an asylum. As early as 1899 he said he had been sick all season and not been himself. In 1900 he was reported to have gone insane at his ranch in Compton, CA but had supposedly recovered from "brain fever, not insanity". He played some minor league ball in 1901 and was expected to continue in 1902.
