Fernando was basically Mark Fidrych with greater longevity. The Dodgers used up his arm and released him by the time he was 30.
He was exactly what the Dodgers needed to win over the Mexican-American fans - there was a lot of hard feeling for the way the city of LA used emminent domain and cleared out the neighborhoods in Chavez Ravine. The Dodgers weren't directly responsible for it, but they were the beneficiaries of it, so many of the Chicanos living in LA had a long memory and bore a grudge.
Fernandomania was something we got to experience secondhand here in Phoenix since the Dodgers games were broadcast on KTAR for years. After his brilliant start he was a dependable workhorse for the Dodgers, throwing 107 complete games for them (about every third start) and averaging about 35 starts a year in his prime.
