Watch Shohei Ohtani strike out 17 during a middle school game

Major League GMs are salivating at the thought of signing 23-year-old Shohei Ohtani to be both their ace and slugger this offseason. But Ohtani didn't emerge out of nowhere -- he's been decimating batters his entire life.

Though there is not full footage from Ohtani's middle-school game, you can watch the Japanese documentary that features the scorecard. Even if you don't speak Japanese, there are some great highlights and cartoons in the video. And that's a language we can all speak. Check it out below:
