The Houston Astros paid their respects to George Floyd in a touching way Monday night ... lighting up their stadium's scoreboard with his picture and the words, "Rest In Power."
The scene was striking ... the 'Stros opened up their stadium so the photo was visible for miles -- and at the bottom of the pic, they typed out "Black Lives Matter."
The team also laid down flowers, a photograph and a candle for Floyd on the Minute Maid Park grass as well.
The Houston Texans also honored the 46-year-old the night before he was set to be laid to rest in his Texas hometown .
