Since no one can agree on what a straight steal of home is, it doesn't exist as a statistic on its own. Just three days before Mondesi's act, Preston Wilson of the Florida Marlins had a so-called straight steal of home with no other players on base. He had almost reached home plate and the ball was barely out of Randy Keisler's left hand. It's something that happens once every five or six years. He picked the right time to go.
Teams are afraid of wasting a scoring opportunity.
