Ken Rosenthal is revisiting his viral mishap from over the weekend ... saying he "felt awful" after knocking a photog to the ground in an attempt to dodge a postgame Gatorade celebration -- and apologizing for the whole ordeal.
Rosenthal addressed the matter on his "Fair Territory" podcast ... claiming the video making rounds after the Milwaukee Brewers celebrated a walk-off win against the St. Louis Cardinals wasn't as bad as it looked -- but his focus was on making sure he did his job.
"I must admit, though, when I looked at the video, I was surprised at how upset I appeared," Rosenthal said.
