Baseball by the Numbers
Sabermetrics — the statistical analysis of baseball — adds a fascinating layer to live viewing. Japanese stadiums are increasingly displaying advanced stats, and understanding them transforms your experience.
Ballpark Factors
Each NPB stadium plays differently. Koshien's famous "hamakaze" (sea breeze) blows from right to left field, affecting home runs. Understanding these factors explains why teams play differently at home versus away.
Stats to Watch
For Batters
Watch for exit velocity (EV) and expected batting average (xBA) displayed on stadium screens. A hard-hit out is actually a better sign than a weak-hit single.
For Pitchers
Spin rate, pitch velocity, and pitch mix tell you about a pitcher's strategy. Watch how pitchers adjust their approach to different batters.
