- 1887 - Per Wikipedia, the National Colored Base Ball League, the first attempt at a professional Negro League, was organized at a meeting in Baltimore. Eight clubs were represented, including the original Pittsburgh Keystones. The league quickly folded (the Keystones finished 3-4), but set a foundation that would eventually allow the Pittsburgh Crawfords and Homestead Grays to enter the baseball scene.
- 1975 - LHP Damaso Marte was born in Santo Domingo, Dominican Republic. He pitched from the Buc bullpen in 2001 and again from 2006-08. He went 7-8-5 with a 3.52 ERA and struck out 200 batters in 186-⅔ IP.
