The first half of September was likely the roughest stretch the 1998 Yankees had to endure. The fatigue of a long campaign was beginning to show, with the team going 6-8 in the first 14 games of the final month of the regular season. That culminated in a 9-4 loss to the Red Sox at Yankee Stadium, dropping the Bombers’ winning percentage below .700 for the first time since the third week of April.
