Anaheim's Kevin Gregg threw four wild pitches—count 'em—in the eighth inning today, tying the "modern" record set by Walter Johnson (1914) and previously tied by Phil Niekro (1979). That is the last time you will hear Gregg's name mentioned with two Hall-of-Famers.

The most wild pitches by someone throwing less than 100 innings was 22 by Ed Crane (Not Kranepool) in just 70 innings for the Washington Nationals in 1886. 1886 was the National's inaugural year, and they went 28-92.
