15. Nolan Ryan (1973 California Angels)
While Nolan Ryan's career ERA might not stand shoulder-to-shoulder with some of the game's control artists, his 1973 season was a pure, unadulterated display of raw, overwhelming power. "The Ryan Express" shattered the modern single-season strikeout record, a mark that still stands today, and threw two no-hitters in the same year, showcasing an arm capable of feats few others could ever dream of. His ability to simply overpower batters with his blazing fastball made every start an event, even if his walk totals sometimes meant a few more runs than desired. It was a season that perfectly encapsulated Ryan's legendary, larger-than-life persona: a pitcher who would challenge you with his best, every single pitch.
