Scary scene during Wednesday's matinee matchup between the Twins and the Mets ... first base umpire Hunter Wendelstedt was drilled in the head by a line drive -- and was forced to leave the game.
It went down in the top of the seventh inning as Tyrone Taylor was up to bat. The New York centerfielder roped a 0-0 pitch foul -- right at Wendelstedt's head.
The collision was so disturbing, the Mets' first base coach immediately waved for trainers to come over.
