For now, SF Giants first baseman Brandon Belt isn't really holding up anything at all.
During regular times, we'd be holding out hope for him to show some improvement after a couple of years of decline, but aside from somebody we probably don't know personally paying him a very large amount of money to play baseball, it doesn't affect us much.
The Giants aren't expected to do much of anything in 2020. It's a rebuilding year. The Dodgers are going to run away with the division (ick). Buster Posey's going to spend time at catcher.
