These awful performances quickly removed the A's from contention. On May 31, they were already nine games out of first place; their position steadily worsened throughout the summer. In light of this, General Manager Sandy Alderson traded Mark McGwire (who, at the time, was on pace to break Roger Maris' single-season home run record) to the St. Louis Cardinals for T.J. Matthews, Blake Stein, and Eric Ludwick. McGwire would finish the season with 58 home runs (four shy of breaking the record). The trade was a disaster on the Athletics' end, as none of the three players received in the trade panned out. The A's ultimately finished twenty-five games behind the first-place Seattle Mariners. Their 65-97 finish (the club's worst since 1979) led to the removal of Sandy Alderson as General Manager on October 17; he was replaced by Billy Beane. Manager Art Howe, however, was retained for the 1998 season.
