Must Read: The Story of Masahiro Tanaka’s Splitter

April 28, 2014 by Mike 18 Comments

The somewhat complicated infield rotation
Monday Night Open Thread

In his worst start of the season last night, Masahiro Tanaka struck out eleven and held the best offense in baseball (by runs per game) to two runs in 6.1 innings. He did that thanks in large part to his trademark splitter, which has generated an insane 58.02% swing-and-miss rate so far. That’s unreal. Johan Santana’s changeup peaked at a 50.86% whiff rate in 2007, for comparison.

How did Tanaka learn that splitter? Jorge Castillo looked into the pitch’s history and it turns out a magazine article about a journeyman American-born pitcher you’ve probably never heard of was the inspiration. I don’t want to give away too much (read the article!), but Tanaka modified the forkball he had been throwing into his current splitter and his career took off. “I probably might not even be here,” he said when asked what would have happened had he never seen the magazine. Here’s the link again. Make sure you check it out. Castillo’s article comes with RAB’s highest recommendation.
