The 5’8″ 160-lb Arano didn’t impress big league scouts but nonetheless became the only pitcher ever to win over 300 games in a single minor league, setting Mexican career marks for games, innings, wins, losses, hits, runs, earned runs, and strikeouts. His totals are complete only through 1984, as 1985 records were lost in the Mexico City earthquake. Except for three games with Oklahoma City at the end of ’62, Arano never pitched outside of Mexico. Breaking in with Aguascaliente, he spent 11 years with the Mexico City Reds and eight with Cordoba, where he twice won 19 games. Arano also pitched for Poza Rica, Veracruz, Saltillo, Reynosa, and Coatzcoalcos.
