The Giants scratched first baseman Brandon Belt from Sunday's Cactus League lineup due to an upper back injury, the San Francisco Chronicle reports.
Belt, who was spotted wearing a wrap on his back, is considered day to day. It doesn't appear to be a big concern for the Giants at the moment.
The 24-year-old Belt is batting .433 this spring over 60 at-bats with seven home runs and 17 RBI, not to mention two stolen bases. He figures to be the opening day first baseman for the Giants as long as he is healthy.
