Rudolph Christian Schwenck (April 6, 1884 – November 27, 1941) was a pitcher in Major League Baseball who played briefly for the Chicago Cubs during the 1909 season.

Prior to the 1909 season, Schwenck, who had been pitching for the Memphis Turtles of the Southern Association, told manager Charlie Babb that he would not be returning to baseball that year and would instead be sticking with his job at a distillery outside of Cincinnati.

[2] An Alabama newspaper article speculated that Schwenck was simply "a sensitive chap at best, and maybe his feelings were hurt" and further argued that, by sticking to the whiskey business, he was passing up on "a golden opportunity to get to the big leagues.

[4] Despite joining the team midseason, Schwenck started the season with a streak of 57 scoreless innings.

[5] His success earned him the attention of several big league clubs including the Cubs, who purchased his services from Memphis for $2,000.
