Chase Field

Construction on Chase Field began in 1996 and was finished in 1998, just before the Diamondback's first season began. It was the third Major League Baseball stadium at the time to have a retractable roof. It was the first ballpark to use natural grass in a retractable roof stadium.

The retractable roof is opened or closed depending on the game-time temperature. Even when the roof needs to be closed for a game, it is left open for as long as possible before the start of the game to keep the grass alive. Even when the roof is closed, the design of the park allows enough sunlight to come in without overheating the stadium.

The roof is closed three hours before game time, and a massive HVAC system drops the inside temperature by 30 degrees by the time the gates open. Originally, this system didn't work above row 25 of the upper level. However, recent changes keep virtually the entire stadium comfortably air-conditioned.

The stadium hosted games 1, 2, 6, and 7 of the 2001 World Series between the Arizona Diamondbacks and the New York Yankees. The Diamondbacks won all four home games, winning the World Series in seven games.

Chase Field was originally named Bank One Ballpark, gaining the nickname "BOB". After Bank One merged with Chase, the stadium was renamed. The change was announced on September 23rd 2005.

Chase Field is slated to be home to the 2011 All-Star Game.
