Atlanta Braves outfielder Nick Markakis just went SCORCHED EARTH on the Houston Astros -- saying he feels the cheating players "needs a beating" for tarnishing the sport he loves.
"It's damaging to baseball," Markakis told WSB's Zach Klein ... "I feel like every single guy over there needs a beating."
Markakis also went off on Commissioner Rob Manfred ... saying he should be "embarrassed of himself" for the way he handled the scandal.
This clip is straight fire -- and it seems like a BUNCH of MLB stars agree with him.
Mark Cuban is ripping MLB commissioner Rob Manfred -- essentially saying Rob's the laughingstock of pro sports for the way he's handled the Astros cheating scandal.
