Overview
A double play records two outs on a single play, with the most common being the 6-4-3 (shortstop to second baseman to first baseman) ground ball double play. It typically occurs with a runner on first when a ground ball is hit to the infield. Double plays can instantly kill a rally, making them one of the worst outcomes for a batter. NPB records 1,200-1,400 double plays annually. Fast runners tend to ground into fewer double plays, while slower power hitters tend to hit into more.
