Daubert hit .261 in 1917, but the following year he hit .308 and led the NL in triples. When the season was cut short due to World War I and the Spanish flu epidemic, major league owners prorated player salaries. Daubert, who had been among the founding members of the Players' Fraternity, sued for the balance of his salary. Eventually, Jake recovered most of the $2,150 he was due. After the dispute started, Brooklyn owner Charles Ebbets traded him to Cincinnati for outfielder Tommy Griffith. Once in Cincinnati, Daubert served as the Reds' captain for the remainder of his career.
