His playing career last for 3 season with the Cardinals and 13 years total. For St. Louis, he played in 210 games with a .305 batting average, 111 RBI and 13 home run. He didn’t play in 1928 but was named player/manager in 1929.
Southworth’s Major League playing career reached the end of the road (1929), as he appeared in only 19 games, five in the outfield, and batted only .188 with six hits. He finished with a .297 batting average in 1,131 MLB games played, 52 home runs, 91 triples, and 561 RBI. He stole 138 bases in his career and had double-digit steal totals in eight seasons. As a big leaguer, Southworth had 1,296 hits in 4,359 at bats.
His 1929 MLB managerial debut was not much more successful than his playing stint. Only one year removed from being a teammate of his charges, he attempted to impose discipline on the Cardinals, banning them from driving their own automobiles. The team did not respond to his hard line and won only 43 of their first 88 games.
