Disclaimer: This video will make you never want to take off your cup again, even if you aren't playing baseball.
In the video above, a pitch deflects right onto an umpire's, um, baseballs during a Korean Baseball Organization game between the SK Wyverns and the Lotte Giants at Sajik Baseball Stadium in Busan, South Korea. Giants pitcher Josh Lindblom hurled the ball that bounced off Park Jae-sang's bat.
The umpire was removed from the field on a stretcher and take to a local hospital for treatment. Ouch.
