Well that's not very sportsmanlike.
College Outfielder Tricks Batter Into Thinking He Caught His Home Run

This is a video from a recent Indiana State vs Iowa college baseball game in which an Indiana State outfielder pretends to catch a Iowa batter’s home run ball, convincing him enough that the hitter stops running and begins to walk off the field. As he does, his teammates urge him back, and the outfielder reveals that he, in fact, did not catch the ball. Now I’m not saying that outfielder is almost certainly a dirtbag and a cheater, but I wouldn’t play cards with him. Not even go fish. *flipping table* I KNOW YOU HAVE THREES.
