The Giants purchased Seymour from the Reds on July 12, 1906 for $10,000 ($ in current dollar terms), the largest monetary transaction in baseball to date. Seymour attempted to hold out from the Giants in order to obtain a portion of this transfer fee, claiming that Herrmann had promised him this money if the sale was completed. McGraw convinced Seymour not to hold out, which could have set a precedent for players obtaining money in player transactions. He batted .286 in 1906 for the Reds and Giants, finishing eighth in the NL.
