As a 27-year-old rookie, Jansen dominated the Pacific Coast League (PCL), leading in wins with an astounding 30 victories, boasting a minuscule earned run average (ERA) of 1.57, and achieving a winning percentage of .833. His ERA remains one of the best in the PCL, a league known for its hitter-friendly parks, underscoring the exceptional nature of his performance.
