Record-Breaking 382 Strikeouts in 1965
Koufax’s 382 strikeouts in 1965 set a modern-era National League record that stood for over five decades. Achieving this across 335.2 innings pitched, his strikeout rate of 10.2 per nine innings was revolutionary for an era when strikeouts were far less common than today.

Career 2.76 ERA Showcases Long-Term Excellence
