Fernando Valenzuela, the Mexican-born Dodgers ace who inspired ‘Fernandomania,’ has died at age 63

Fernando Valenzuela, the Mexican-born phenom for the Los Angeles Dodgers who inspired “Fernandomania” while winning the NL Cy Young Award and Rookie of the Year in 1981, has died. He was 63.

The team said he died Tuesday night at a Los Angeles hospital, but did not provide the cause or other details.

His death comes as the Dodgers prepare to open the World Series on Friday night at home against the New York Yankees.

Valenzuela had left his color commentator job on the Dodgers’ Spanish-language television broadcast in September without explanation. He was reported to have been hospitalized earlier this month. His job kept him as a regular at Dodger Stadium, where he held court in the press box dining room before games and remained popular with fans who sought him out for photos and autographs.

Valenzuela was one of the most dominant players of his era and a wildly popular figure in the 1980s, although he was never elected to the Baseball Hall of Fame. However, he is part of Cooperstown, which features several artifacts including a signed ball from his no-hitter in 1990.

This is a developing story.
