Times Have Changed

The highest career strikeout-to-walk ratios in baseball history, given an admittedly embarrassing minimum of 150 innings pitched:

↵1) Koji Uehara, 7.0
↵2) Sergio Romo, 5.4
↵3) Edward Mujica, 5.0
↵4) Rafael Betancourt, 4.6
↵5) Kevin Slowey, 4.6

↵All of these pitchers are active. The highest inactive pitcher on the list is Curt Schilling, at #6. The highest inactive pitcher from another era is Cy Young, at #15, and then either Tom Henke (#39) or Juan Marichal (#50).
