Dodgers legend and six-time All-Star Fernando Valenzuela died Tuesday evening, Major League Baseball announced.

He was 63.

A cause of death was not given.

“Fernando Valenzuela was one of the most influential players of his generation,” MLB Commissioner Rob Manfred said in a statement Tuesday night. “With his distinctive pitching style, the Dodgers left-hander’s rookie season caused so much excitement in the United States and his native Mexico that it was widely referred to as ‘Fernandomania.'” His 1981 season ranks as one of the most successful pitching years of all Times when Fernando was the National League Rookie of the Year, NL Cy Young Award winner, Silver Slugger and World Series champion.

After beginning his professional career in Mexico, Valenzuela signed with the Dodgers in 1979 and made his MLB debut in 1980 at the age of 19.

He really came into his own a year later when he won the National League’s Cy Young, Rookie of the Year, and made his first All-Star team, thanks to his dominant nature and unusual pitching style in “Fernandomania.” Los Angeles took over where he looked to the sky in the middle of his winding up.

In the 1981 season, in which he was also awarded the Silver Slugger, he helped the Dodgers defeat the Yankees in the World Series.

Valenzuela went 3-1 in the postseason and earned a nine-inning win in Game 3 of the World Series.

He spent 17 years in the major leagues, including 11 years with the Dodgers, winning 173 games and recording 2,074 hits with a 3.54 ERA.

The southpaw led the NL in complete games three times during his career, including the 20 he threw in 1986, which was the highest point total in the majors.

He served as the Dodgers’ Spanish-language broadcaster for the past 22 years, but left the job in September and was hospitalized in early October, the Associated Press reported.

“He is one of the most influential Dodgers of all time and belongs on the Mount Rushmore of franchise heroes,” Stan Kasten, president and CEO of the Los Angeles Dodgers, said in a statement. “He thrilled the fan base with the ‘Fernandomania’ season in 1981 and has been close to our hearts ever since, not only as a player but also as a presenter. He left us far too soon. Our deepest condolences go out to his wife Linda and his family.”
