While the team at bat is trying to score runs, the team in the field is attempting to record outs. In addition to the strikeout, common ways a member of the batting team may be put out include the flyout , ground out , force out , and tag out . It is possible to record two outs in the course of the same play. This is called a double play . Three outs in one play, a triple play , is possible, though rare.
