The baseball world mourns the passing of legendary closer Willie Hernandez, who died on Monday at the age of 69.

Hailing from Puerto Rico, Hernandez was one of the best relief pitchers of his 1980s. The dominant left-hander crafted a stellar 13-year MLB career from 1977-1989, making three All-Star teams while pitching for the Chicago Cubs, Philadelphia Phillies and Detroit Tigers.

Hernandez began his career with the Cubs, who drafted him from the Phillies in the Rule 5 Draft in 1976. He debuted for Chicago the following year at age 22 and enjoyed immediate success, going 8-7 with a 3.03 ERA in 110 innings as a rookie.
