Repeaters

On August 28, 1992, Mark Gardner became the first pitcher to record his 2nd career plunking of Craig Biggio. Since then, Biggio has been hit by someone who had already hit him at least once in every season. In 2001, 9 of Biggio's 28 HBPs were thrown by someone who had hit him before - the most of any season. In 1999, Biggio collected his highest percentage of plunks by past offenders, with 5 of his 11 plunks coming from pitchers who had already hit him at least once.
In the 2004 season, 91 pitchers who had plunked Biggio pitched in the Major Leagues, but even though that number was at its peak, only 3 hit Biggio that season.
