Incredibly gross scene at Yankee Stadium on Monday ... Angels pitcher Dylan Bundy was so bothered by the New York heat, he straight-up blew chunks all over the mound!!
It all went down in Los Angeles' tilt with the Yankees ... where temperatures in the 90s had Bundy REALLY not feeling so hot.
The 28-year-old struggled to pitch to his first few batters of the night -- giving up four hits and two runs -- and then late in the 2nd inning, you can see he really wasn't doing well physically.
