Mike Trout described his first major league grand slam as "just another home run." Teammate Garrett Richards was pretty grateful just the same for the nine-run first inning to support him against Detroit's Rick Porcello. Trout's second homer of the season capped the Angels' most productive first inning in almost 18 years, and Richards pitched two-hit ball over seven innings in a 10-0 romp over the defending AL champion Tigers on Saturday.
