Belt (neck) is starting at first base and batting second Tuesday against the Rockies, Amy Gutierrez of the Giants' official site reports.
Belt was listed in the lineup each of the past two days before ultimately being scratched with neck stiffness, and he's once again in the starting nine. Assuming the 34-year-old actually plays Tuesday, it will be only his second appearance since being activated off the COVID-19 injured list Saturday.
