The Ripken Brothers joint stint in Baltimore, while managed by their father Cal Sr. from 1987 to 1988, marked the first time a father has managed two of his sons on the same team in the bigs.
• September 15, 2003: With his 2,063rd career base on balls, Barry Bonds passes Babe Ruth on the all-time walks list. The Giant left fielder now only trails Rickey Henderson, who has 2,190 free passes.
