The Rockies overcome a 7-run deficit to defeat the visiting Giants, 17 – 13, as 3B Jeff Cirillo slugs a double and three home runs, drives home six runs, and scores five himself. Cirillo’s third homer, a 2-run shot off John Johnstone, breaks a 12 – 12 tie. The Rockies draw their 20 millionth fan to one ballpark faster than any other team in major league history. Taking less than six years, Colorado eclipses the Dodgers’ mark of taking nine years in two stadiums to reach the milestone.
