- 1873 - Utilityman Tom O’Brien was born in Verona. O’Brien played just two seasons for his hometown club (1898, 1900), hitting .274 for Pittsburgh before meeting an untimely death in 1901.
- 1877 - The International Association (so-called because it had a pair of Canadian clubs) was formed in Pittsburgh with the Alleghenys as one of the charter teams. Some baseball historians consider it to be the first minor league; others think the league was conceived to rival the National League. It was fairly short lived, folding after the 1880 season. It really didn’t have much a schedule; Alleghenys’ ace Pud Galvin tossed 18 of the 19 IA games played that first year.
- 1920 - All-Star infielder and restaurateur Frankie Gustine was born in Hoopeston, Illinois. He played 10 years (1939-48) for the Bucs, hitting .268 as a Pirate and earning three All-Star spots. Gustine later became the head coach at Point Park College from 1968-74, and operated a bar/restaurant on Forbes Avenue in Oakland a few steps away from Forbes Field.

- 1928 - The Baron of the Bullpen, ElRoy Face, was born in Stephentown, NY. He pitched fifteen years (1953, 1955-68) for the Bucs, going 100-93-188/3.36. Face was the first major leaguer to save 20 games more than once, leading the league three times and finishing second three times; in 1959 he set the still-standing major league record for winning percentage (.947) at 18-1, winning 22 games in a row over two seasons (19548-59). He held the NL record for career games pitched (846) from 1967-86, and the league record for career saves (193) from 1962-82. Face still holds the NL record for career wins in relief (96), and he held the league mark for career innings pitched in relief (1,211-1/3) until 1983.
- 1999 - The Pirates signed free agent SS Pat Meares to a $1.5M contract. In April, they extended the deal through the 2003 season for $15M. He broke his hand early in 1999, had surgery, and was out of baseball by 2002, having played 240 games for the Bucs while hitting .238.
