Oakland Coliseum

As early as 1961, the American League (AL) publicly indicated that it wished to include Oakland in its West Coast expansion plans. , though these expansion plans seemed to fade by the middle of the decade.
After approval from the city of Oakland as well as Alameda County by 1962, $25 million in financing was arranged.

Plans were drawn for a stadium, an indoor arena and an exhibition hall in between them.
The architect of record was the San Francisco office of Skidmore, Owings & Merrill and the general contractor was Guy F. In 1965, it was rumored that the Cleveland Indians might leave Cleveland for a West Coast city (such as Oakland) but the Indians ended up remaining in Cleveland.

Charlie Finley, owner of the Kansas City A's, unhappy in Kansas City, impressed by Oakland's new stadium and personally convinced to consider Oakland by Nahas , eventually got permission after several unsuccessful attempts, and amid considerable controversy, to relocate his American League franchise to the Coliseum for the 1968 season (for details on the controversy, see the separate articles for the A's and the Kansas City Royals, the expansion franchise created to replace the A's in Kansas City).
The Raiders played their first game in the Coliseum on September 18, 1966. In 1968, the Kansas City Athletics became the Oakland Athletics and began play at the new stadium.

The stadium complex cost $25.5 million to build and rests on 120 acres (0.5 km²) of land.
The Oakland-Alameda County Coliseum Complex consists of the outdoor stadium and the indoor arena. For many years the outdoor stadium was commonly called "the Coliseum", while the arena was called "The Coliseum arena." More recently, only the stadium is called the Coliseum.

The arena, which was extensively renovated in 1996-97, is now called Oracle Arena, and since the early 1970s has been home to the Golden State Warriors basketball team of the NBA. Consequently fans entering the stadium find themselves walking on to the main concourse of the stadium at the top of the first level of seats.Wolff and Cisco Systems conducted a Press Conference at the San Jose-based headquarters of Cisco Systems on November 14, 2006 to confirm the deal, and showcase some details of the future plan.
Under any such replacement proposals, the Oakland Raiders would continue to play football in the Coliseum.
Mount Davis


The Mount Davis structure; during baseball season the seats are not sold and are covered with a tarp.

One feature of the 1996 expansion was the addition of over 10,000 seats in the upper deck that now span the outfield in the baseball configuration (and face the setting sun late in the day during NFL games). The effect of these new stands, comprising sections 335–355, was to completely enclose the stadium, eliminating the spectacular view of the Oakland hills that had been the stadium's backdrop for 30 years.
The stands are very narrow and steeply pitched, bringing the back row of its upper-most tier to a height rarely seen in modern stadiums.

Due to the stands' height and the loss of the Oakland hills view, A's fans have derisively nicknamed the structure Mount Davis or the AL-ps, in (dis)honor of Raiders owner Al Davis.
It has been criticized as an area which has made the Oakland-Alameda County Coliseum look ever more like a football stadium, and not at all one for baseball. From 1997 through 2004, the A's left the section open, but it was rarely filled except for fireworks nights and the postseason. For the 2008 season, Sections 316–318 of the 3rd deck behind home plate were re-opened as the A's introduced their own "All-You-Can-Eat" seating area, similar to the right field bleachers at Dodger Stadium.

This has increased the Coliseum's capacity for baseball to 35,067 - still very small. Prices for these seats are $30/game for season ticketholders, $35/game for most series, and $38/game for series against the New York Yankees, Boston Red Sox, and San Francisco Giants.
