Instant replay for the MLB has changed the game of baseball in some what of a dramatic way especially the base running part of the game. Most calls that were missed ether helped or hurt teams by ether giving them momentum or taking it away from them. Before instant replay when a call was missed it normally meant the out come of a came it meant wether you won or lost that game. Now with this instant replay it has changed it and has corrected these mistakes now when ever an umpire misses a call normally the call that helped out the other team and usually gave them momentum now takes that away because now they can go back see that they screwed up. This helps out the teams that it goes against and gives them the momentum and ether helps them win or keeps them ahead. It has also made tag plays more physical in the sense that you kinda have to tag them so incase the umpire misses the call you can't fake a tag play anymore your going to have to have proof that you did indeed tag them out. Most players back them would just swipe and make it look like they tagged them when instead came no where close to them and this is going to make the game more physical because now players are going to have to stay in front of the bags and act like a catcher on close plays. So this might lead to more injuries with these tag plays but not really since you can't take out the catcher at the plate. Which it doesn't make the game as interesting any more. But in reality instant replay has somewhat helped the game of baseball it has helped umpires fix their mistakes and lead to less ejections and less controversy.
