Answer
Pedro Martínez's career strikeout rate per nine innings is 10.04, an exceptional statistic that ranks him among the most dominant pitchers in baseball history. This means that for every nine batters he faced, Martínez struck out an average of more than 10. This remarkable ability to generate strikeouts was a key factor in his success, as he consistently overpowered opposing hitters with his devastating fastball and changeup combination.
