Belt is out of the lineup for Sunday's game against the Brewers.
Since returning from the injured list Thursday, Belt started in each of the Giants' past three games, going 4-for-12 with three home runs and five RBI. The lefty-hitting Belt should be locked in as a strong-side platoon player the rest of the way, but he'll give way to the right-handed Darin Ruf at first base with the Brewers bringing southpaw Brett Anderson to the hill for the series finale.
