The Houston Astros superstar was just DRILLED for the first time since he was revealed to be a cheater ... and it all begs the question -- HOW MANY MORE TIMES WILL IT HAPPEN THIS YEAR?!

The 3rd baseman stepped up to the plate in the 5th inning of Houston's spring training game against the Cardinals on Wednesday ... and he WORE one right in the back.

Bregman said afterward he didn't think it was intentional -- "It was a splitter. It just got away from him" -- but, COME ON!!!!!!

The HBP sure seemed fishy to us ... you can see the pitch -- on a 3-2 count, nonetheless -- plunked Bregman SQUARELY between the shoulder blades.

And, as you can tell from Bregman's reaction ... it wasn't exactly a lollipop!!

Of course, the 'Stros are likely going to face this all season long after the MLB announced it found they cheated their way to a World Series title in 2017.

In fact, ex-MLB star Aubrey Huff told us just a few days ago he sees this happening REGULARLY to the 'Stros in 2020.

And, according to the unofficial counter on Twitter ... Bregman's hit by pitch marked the SEVENTH time a 'Stros player has been plunked so far this spring.
