A Time To Learn

Recently, a news organization decided it would be interesting to see if Major League Baseball players knew the rules of their game. They composed 10 questions about various scenarios. On average, the players answered 5.5 of these true-or-false questions correctly.
Lack of knowledge of the finer points of baseball rules can sometimes affect the game. In 2003, a player on the Athletics did not understand baseball’s obstruction rule and made a crucial out in what could have been a decisive rally in a division series. Miguel Tejada was rounding third when he collided with third baseman Bill Mueller. The umpire ruled that Mueller obstructed Tejada, the runner. Tejada assumed the play was dead and leisurely jogged home, only to be tagged out. The umpires ruled that he was indeed out.
Obstruction only results in a dead play if the obstruction happens near the ball. Since the baseball was nowhere near third base, the play continues even after the obstruction call. The umpires then use their discretion to see if the obstruction affected the play. If Tejada had run home and been out by a step, the umps would have ruled him safe, based on the obstruction call.
