T-20: Chase Field (Arizona Diamondbacks)
Aside from the huge jumbo-tron and pool in right center, Chase Field is kind of bland. Also, the lack of an actual fence in center field, and use of a line to judge a home run is kind of strange.
It was opened in 1998, and has seen the D’Backs capture a World Series here, as well as host an All-Star Game. It is also one of two ballparks to feature a dirt strip from the pitchers mound to home plate, the other being Comerica Park.
