In November 2006, the future of the Oakland A's looked bright, as the team announced plans to build a new ballpark in Fremont, CA. Those plans have been derailed due to increased opposition from major retailers and the owner of the stadium site, west of Interstate 880, near the Pacific Commons shopping center. Upon announcing plans to build a ballpark, the Oakland A's sold the naming rights to the ballpark to Cisco Systems for $4 million/year over 30 years.

The ballpark design simultaneously mimicked classic ballparks of the past and contained some of the most advanced technology in the world. If constructed, it would have been the smallest in Major League Baseball, seating up to 34,000 fans. The main three tier grandstand would extend from the left field foul pole to homeplate, and down the first baseline to right field. Additional seating would be found in both right and left field. The break down of seating consisted of field level box seats, 66 four person mini seats 15 rows behind homeplate, lower reserved seats, 41 luxury suites and rooftop box seats. The main video/scoreboard would have been located beyond the left/centerfield fence. Early estimates had the ballpark originally opening in 2009 and later 2011. In April 2008, the A's announced the earliest Cisco Field would open is 2012. However, in 2009, opposition mounted against the A's proposal near Interstate 880 and Auto Mall Parkway from both citizens and businesses. The A's also proposed that their new ballpark be built in the Warm Springs area, near a future BART station. However, this proposal did not gain any support from the Fremont community. It unfortunately appears that the A's will have to develop a new ballpark plan that may lead the team to building a new ballpark in Oakland, near the coliseum or possibly in San Jose, CA.
