1.  What are the two most used ways to defend the push bunt?  Which way do you think is more effective?

Answer:  A push bunt is any bunt toward the 1st base side of the infield.  The defense has 2 options for defending against a push bunt: (1) First baseman charges the baseball and the second baseman covers 1st base; or (2) the 2nd baseman charges.   Both of these plays are difficult, but they are both commonly used, just depending on who is comfortable with what.  In high school and college, the coach will usually decide who charges the baseball and who covers first base.  At the pro level, it will be up to the players to work it out.

I personally think that if it’s not where the first baseman can field it and touch the bag himself he should let the 2nd baseman field it.  It is more difficult for the 2nd baseman to race over to first base and stop on the bag.  If he goes past the bag he will collide with the runner.
