1989

The commissioner's office announces that Reds manager Pete Rose is under investigation for unnamed "serious allegations."

I wonder how that turned out.

1973
In a special election held by the BBWAA, the late Roberto Clemente receives 393 of 424 votes to earn entry in the Hall of Fame. The Hall's Board of Directors had earlier waived the 5-year-wait rule for Clemente.

I wonder who the 31 guys were that didn't vote for Cemente.

1915
The Braves break ground on Commonwealth Avenue and begin construction of Braves Field. Owner Gaffney wants a large enough park so that inside-the-park homers can be hit in three directions. The field will open on August 18th.

I wonder if there are any pictures of Braves Field.
