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.
