You can check out a video of him being the first player in the KBO to hit the roof of the newly opened Gocheok Sky Dome (고척스카이돔). Everybody was a bit confused about what had happened because they didn't know if it should have been ruled fair and a ground rule double or if it should have been ruled foul. You see a couple of the umpires making different calls. The umpire at 3rd called it fair and the umpire at 2nd called it foul. After the replay it was ruled fair and a double.
