Fernando Valenzuela, the impetus behind "Fernandomania" while winning National League Cy Young Award and Rookie of the Year honors in 1981 as the Los Angeles Dodgers won the World Series, has died at age 63.
The Dodgers announced the news, saying Valenzuela died Tuesday night at a Los Angeles hospital. They did not provide the cause or other details.
Valenzuela's death comes as the Dodgers prepare to open the World Series on Friday night at home against the New York Yankees. Major League Baseball commissioner Rob Manfred said Valenzuela would be honored during the Series at Dodger Stadium.
