Batters in the 1990s are increasingly swinging for the fences (and also whiffing at air), and nowhere is that more evident than at mile-high Coors Field in Denver, where the Colorado Rockies play arcade baseball. But the Rockies aren't the only team hitting home runs and crossing the plate in record numbers; in fact, it's a league-wide trend. This unique reference compares the 1993-97 offensive surge with prior offensive peaks in the 1920s and 1930s. Combining baseball history with data not available elsewhere, it explains the origins of the 1993-97 increase in offense and follows the trend into the future. The work is divided into four parts: League Comparisons, Team Comparisons, Team Summaries and The Future. In 69 tables and 15 figures, league and team records for eight basic measures are ranked.
