As we overlook the fact that the 2025 MLB playoffs kicked off at the end of September and could conclude by early November—recognizing it’s always October for playoff baseball—let’s pose a question: Who is this year’s Mr. October?
What if I mentioned it’s a notable Japanese pitcher on the Los Angeles Dodgers known for his exceptional splitter? While that may not be as precise as expected, I suspect that the name that came to mind is Shohei Ohtani. However, the current frontrunner is Roki Sasaki.
This conclusion is drawn from Win Probability Added (WPA), a valuable statistic that provides insight into the narratives that unfurl throughout the postseason.
As the only remaining wild-card team, the Dodgers have endured an additional round, with Sasaki currently holding the top playoff WPA at .706 among the final four teams. Here’s a breakdown of his performance:
Oct. 1: .015 (He ended the final inning of an 8-4 victory over the Cincinnati Reds, showcasing his skills despite a less critical situation.)
Oct. 4: .099 (He secured the final moments in a 5-3 Game 1 win against the Philadelphia Phillies. Excitement is definitely in the air.)
Oct. 6: .208 (Although he faced just one batter, he significantly impacted the game by securing the last out, leading the Dodgers to a favorable series position.)
These statistics embody the evolving stories throughout the playoffs, as we consistently monitor these numbers moving forward. Keep an eye out for updates on our leaderboards.
