Frank Howard, a four-time All-Star who slugged 382 home runs during a lengthy major league career that included a World Series title with the Los Angeles Dodgers in 1963, has died. He was 87.

A spokesperson for the Washington Nationals said the team was informed of Howard's death by his family Monday. A cause of death was not provided.

"He was the ultimate teammate," Dick Bosman, who played six-plus seasons with Howard with Washington and Texas and remained friends with him for decades, told The Associated Press on Monday. "Next to my dad, he's the greatest guy I know."
