MY STORY:

BASEBALL MY FAVORITE SPORT

Baseball is a sport in which skill is combined with physical abilities and athleticism. Baseball is my favorite sport because it is fun and a good form of exercise. Most of the players see it as an amazing sport even though some might just do it as a hobby. Sometimes adults and even kids play baseball to get some sort of relief from the stress we are exposed to on our daily life. Baseball is a great form of getting into shape and also enjoying fresh air and even socializing as it is a team sport.

    Baseball is a sport for everyone, if you cannot play you can sit on the bleachers and watch the game. To me and others watching a baseball game is very entertaining. I love not just watching but playing it as well. Participating in a sport such as baseball can be so amazing, seeing your team’s efforts, your team’s victories and even your team’s losses is a great feeling knowing it was all done together as one. Baseball is sometimes called the “National Pastime” of the United States. As online research confirms Baseball is considered a big part of the United States history and culture, it has been around for a long time. Baseball rules can be confusing sometimes but once you get the hang of it, you can see the grace and beauty in each and every game.

    Baseball to me is overall an amazing sport. I feel like baseball promotes many good things like team work, and also the understanding of winning and losing. Baseball is not just a sport it’s a passion, a hobby and a great form of entertainment. I and many others believe Baseball is a great sport. Baseball is a sport that will continue growing and getting better with time. Baseball will always remain my favorite sport as I share the love for this game as many Americans do.
