Greg Maddux notes

In 1994 Greg Maddux posted the best season WHIP (walks + hits per inning pitched) ever for a pitcher who hit Craig Biggio with a pitch that same year, with .896. Pedro Martinez is the runner up with his 1997 season WHIP of .932.
Maddux also leads all Biggio plunkers in career wins (307), strikeouts (2950), shutouts (35), and innings pitched (4,236). He is only 6 losses behind Danny Darwin's career total for second place on that list (Maddux: 176, Darwin: 182), but isn't likely to match Frank Tanana's 236 losses.
Maddux plunked Biggio on 7/31/1993 and 6/12/1994.
