We often call for fake bunts in various situations to see how the defense reacts. One play we have used numerous times this year is bunting with a runner on first and having that runner go directly to third without stopping. You would be surprised how many teams have the corners crash the bunt but then leave third base unprotected.
I quite like this option, as I believe the odds are good, given the left fielder is hustling in or the pitcher or third-baseman are getting back after the other goes for fielding the bunt. Odds of making it are fair.
