The BBWAA was authorized to elect players active in 1950 or later, but not after 1964; the ballot included candidates from the 1969 ballot along with selected players, chosen by a screening committee, whose last appearance was in 1964. All 10-year members of the BBWAA were eligible to vote.
Voters were instructed to cast votes for up to 10 candidates; any candidate receiving votes on at least 75% of the ballots would be honored with induction to the Hall. The ballot consisted of 46 players; a total of 300 ballots were cast, with 225 votes required for election. A total of 2,302 individual votes were cast, an average of 7.67 per ballot.
Candidates who were eligible for the first time are indicated here with a dagger (†). The one candidate who received at least 75% of the vote and was elected is indicated in bold italics; candidates who have since been elected in subsequent elections are indicated in italics.
Sid Mercer (1880–1945) received the J. G. Taylor Spink Award honoring a baseball writer.[2] The award was voted at the December 1969 meeting of the BBWAA, and included in the summer 1970 ceremonies.
