66

After years as a respected power/speed threat with a rocket arm in right field, he emerged during the 1998 as one of baseball's greatest. It was in this season that both Sosa and Mark McGwire were involved in the "home run record chase", when both players' prowess for hitting home runs drew national attention as they attempted to pass Roger Maris' single season home run mark of 61 home runs that had stood since 1961. Sosa ended the season with 66 (still a team record), behind McGwire's 70. However, Sammy had become the first Major League batter ever to hit 65 homers in a season. Then, McGwire passed him late in the season to become the first ever to hit 70. It was during that season, that Cubs announcer Chip Caray nicknamed him "Slammin' Sammy," a nickname that quickly spread.
