Roush won his second batting title in 1919, when he led the league with a batting average of .321, and led the Cincinnati Reds to the World Series. The Reds won the 1919 World Series, known for the Black Sox Scandal, by winning five of the eight games. Throughout his life Roush would state that the Reds were the better team, and would have won the Series either way. Roush showed up for spring training in 1920, an occurrence rare enough that The Sporting News reported on it. Roush would hunt quail and rabbits at his home in Oakland City, Indiana right until a week before opening day. On June 8, 1920, a lengthy argument took place on the field, and Roush fell asleep in the outfield. After infielder Heinie Groh was unsuccessful at waking Roush up, Roush was ejected for delay of game. Roush hit .339, and set career highs in hits, doubles, triples, RBI, and total bases.
