Fenway Park (Boston Red Sox)
	This stadium is so old. It was built in 1912,so almost 100 years! Because Daisuke Matsuzaka became a member of Red Sox, this stadium would be more famous for Japanese people. However, this has been already very famous for Americans and other Major League Baseball (MLB) fans for some reasons!!!! 1. Green Monster As you can see in left picture, the left-side fense is very high! This fense is called "Green Monster" because it often prevents home-runs. Its height is about 11.2 meters.   2. Rivality Red Sox and NY Yankees has had very huge rivality, so many fanatic fans visit and cheer for Red Sox's victory, especially the game against Yankees.
Minute Maid Park (Houston Astros)
	This stadium has one of the most complicated structures in all ballparks. 1. Slope Surprisingly, this staduim has the slope that is 30 degree within the field. Maybe you can find it in the left picture. The slope is located on the back of the outfield. 2. Pole On the slope, one pole is standing anytime. I think it is meaningless, but players  should care about it when they are playing. 3. Train There is a train railroad. It is on the bridge-like structure in the picture. It does not affect the play, but trains always appear and run when players hit the home-run.
Angel Stadium of Anaheim (Los Angeles Angels)
	This stadium was owned by Disney before, so There is an attractive  structure  left. 1. Waterfall As you can see in the left picture, there is a rocky hill within the outfield stands. When Angels players hit the home-run, the water starts to fall like a waterfall from the top of the hill. Also, this Stadium is located near Disney Land, so it is very good course for dating with your boyfriend or girlfriend!!
Citizens Bank Park (Philadelphia Philies)
	This is the ballpark in the city of independence, so sometimes the president throw out the first pitch as a ceremonial first pitch. Although it does not have very unique struture,  it is the staduim that is the most easiest park for hitting home-runs because of its size and structure. 1. Home-run heaven There is more possibility to see the big home-runs than other stadium! If you want to see slugfest, it is the best place to go!
