What are baseball double-play combos and how do they work?

Answer 1

The term 'double play combo' refers to the second baseman and the shortstop. The law of averages says that most balls hit in the infield are going to be hit to either the shortstop or the second baseman since they are playing towards the middle of the field. So most of the double plays a team makes are with the second baseman, shortstop, and first baseman.
