Check out this Baseball Reference post passed along from the Inquirer's Matt Gelb.

Longest Streak with BB=0 From 1916 to 2013: Results – Baseball-Reference.com
The 1919 Phillies did not walk in seven straight games; "modern baseball history", Gelb notes usually is consider to have begun around 1919, the end of the dead ball era.
Without baserunners, one does not have a difficult time understanding why the Phillies cannot score any runs.
