Mets manager Gil Hodges emerged from the dugout, walked past Nolan Ryan on the mound and all the way to left field. A few minutes later, Hodges walked back to the dugout, with Jones a few paces behind him, and replaced Jones in left with Ron Swoboda. According to Jones, he pointed down to the water-filled turf. Hodges then said that something must be wrong with Jones' ankle and pulled him for that reason (Jones was kept out of the lineup for the next two games and was used only as a pinch hitter in the two after that). Newspapers report that Jones was removed for failure to hustle, and Hodges decided to do so publicly to show that he would not tolerate lack of effort on his team, even from its star player.

Holtzman survives a scare in the seventh as Hank Aaron's fly ball to deep left field leading off the inning appears to be going over the wall for a home run; however, a stiff wind cuts into the ball and enables Billy Williams to catch it at the warning track.
