Aubrey Huff says there's going to be A LOT of bruises on Astros players' backs this year ... saying the punishment for their cheating scandal is going to be all-out bean wars in 2020!
"I would suggest a lot of those guys -- especially Altuve and Bregman -- wear bulletproof vests up to the plate all year long!" Huff tells TMZ Sports.
Of course, ZERO Houston players were punished for their roles in the 2017 cheating scandal ... and a LOT of people are pissed off about it.
