 something that we have mentioned before but have never really gone into detail about is something called an appeal play. And an appeal is a way for the defensive team to kind of bring to light something that the offensive team has done incorrectly but that it's not an automatic out. So it's not the umpire's responsibility to catch it and calling out. The the defensive team must specifically bring this to the umpire's attention and then he has the the opportunity to make a play or make a call on the play. So how do appeals work? Well first they must be made before another pitch or play takes place. So it must take place before another pitch play or or attempted play. An attempted play would be something like a a pick-off attempt on a base runner by the pitcher and then the rules also say that if it occurs at the end of a half inning then the appeal must be made before the players leave the field. So if the end of a half inning must be made leave and and and another guideline that it gives us is that multiple appeals cannot be made on the the the same runner at the same base. So so only one one appeal per situation or runner base and this this means basically if if well let's get into to how an appeal is made. So and then we'll come back and look at what that means specifically. So if we have an appeal say in the first way the the rules say the first situation is that if a fly ball is caught the runner fails to retouch his original base before the base is tagged and so this is something that we'll see a lot on on sacrifice flies. So if we have our our our fielder out here and we have a base runner here on third base and the the batter is up and he hits a fly ball there's less than two outs and he hits a fly ball out to the left fielder and this runner on third base waits until the the the ball is caught he and then he would he would run home for for the sacrifice fly he'd tag up and and complete the sacrifice fly. But if in the event the runner he tries to get too much of a head start and he actually leaves the base and runs home before the the left fielder has caught the ball then in that situation it this this is a play where the defensive team can make an appeal and so so what would happen is that the the pitcher usually is the pitcher would get the ball and the we'd have the third baseman and so the maybe the ball came back in here and the the pitcher would throw the ball to the third baseman and this runner here the this runner on third base you know right here he ran home so he's maybe in the dugout the the pitcher would throw the ball to the third baseman the third baseman would step on third base and they would they would ask the umpire for an appeal and in that situation if the umpire who should have during the play been watching the runner to make sure he was he was you know leaving at the appropriate time if the umpire deems that the runner left early then he's going to call that runner out on the appeal or if the umpire feels that that he did wait long enough and he would he would call him safe in the play would just it would just be the normal sacrifice fly so so that would be the appeal plays basically the the player getting the the ball and stepping on the base that they would like to appeal at so this this one appeal per runner at base that means that if we had this situation and the ball maybe in the the pitcher went to throw the ball to the third baseman and and something happened and say the ball he made a horrible throw and he threw the ball out of play into the crowd or something then that means the defensive team would not be given another chance another opportunity to appeal that play and then the the runner just he would have scored so so let's write this this one down so we can say say that the runner is out after appeal if he fails to retouch his original base before base this tag so that's that's that's one way and so that that that example there with the sacrifice fly that's only one of of quite a few situations where where that that will come into play but that's probably the most common or where you'll see that
