I don’t see many, if at all, national endorsement deals for baseball players, beyond Ohtani. I never see Judge, Trout, etc.. in any commercials or sponsorships.
Skubal is the best pitcher on the planet, and he’s schlepping local Cure Insurance.
I don’t think endorsements will factor in much for a guy like Bregman, who at best, will get a local car dealership, regardless of the market he selects.
