On July 7, 1993 In Philadelphia, the Phillies defeat the Dodgers, 7 – 6, in a 20-inning marathon when Lenny Dykstra hits a bases-loaded two-run double off Rod Nichols. The game takes 6 hours and 10 minutes, and concludes at 1:47 AM. The Phils’ Mitch Williams blows a 5 – 3 lead in the 9th, allowing a hit and walking three before being ejected by umpire Jim Quick. Afterwards, John Kruk says, “I came here and I wanted to kill Mitch, but they told me it was against the law.” Phils rookie Kevin Stocker makes his major league debut, playing all 20 innings.
