He was a member of the Orioles' Kiddie Korps pitching staff in the early '60s and had an amazing rookie season in 1960, when he tied for the league lead in Wins with 18 and had a very respectable 3.58 ERA. He was rewarded by being named to the All-Star team, receiving MVP votes and coming in 2nd place in ROY balloting. (Side note-3 Orioles players received all of the 1960 AL ROY votes; Ron Hansen won the award, and Estrada and Jim Gentile tied for second place with 1 vote each. Maybe the 2009 or 2010 O's can sweep the ROY voting again!)
Estrada always had some control problems (think Daniel Cabrera) and things started to unravel for him quickly after his great rookie season. He was among the league leaders in wild pitches, walks and hit batters in 1961 & 62 and led the AL with 17 losses in 1962.
Chuck was out of baseball by age 29 in 1967 , but served as a pitching coach for the Rangers (1973) and Indians (1983) since his playing days ended.
Since his playing career ended, he has started the Don Ferrarese Charitable Foundation which helps California youths obtain school scholarships. Way to be, Don.
He is the father of current Red Sox manager Terry Francona.
