First off, thank you so much for translating this series. It's my favorite release on this website and I always look forward to the chapters.
Second off, it's really interesting that Shimizu thought of that. A good baserunner in real life can really disrupt a pitcher's rythm and mess with the catcher's strategy. Don't think that throw to the center fielder trick would work in real life though, it'd be very obvious considering how far the CF would have to move to get there. Also, leaving the CF spot abandoned is asking for big trouble but I'm sure Kaido don't have to worry about plebian batters actually making contact with the ball.
