What happened: San Francisco was up 10-3 over St. Louis when Hill got his first big-league home run. He reached the milestone barely a month after making his MLB debut on Aug. 15.

Why it matters: The swing adds another data point to Hill's quick climb from debutant to September contributor. It also gives San Francisco another reason to keep looking at the same Turner Hill who had seven RBIs in six games earlier this month.

What to watch: Watch whether Hill's first homer turns into a larger role over the final weeks of the regular season. The next few lineup cards will show whether this was a milestone moment or the start of more everyday at-bats.
