The Athletics dedicated the Coliseum's playing surface "Rickey Henderson Field" in honor of MLB Hall of Famer and former Athletic Rickey Henderson as part of Opening Day on April 3, 2017. RingCentral placed a bid for the naming rights on May 14, 2019, for a $1 million annual payment. The Oakland–Alameda County Coliseum Authority gave its approval of the new naming-rights deal on May 31, 2019 pending formal approval from Major League Baseball. New signage was in place by the time that the Golden State Warriors hosted the 2019 NBA Finals at the neighboring Oracle Arena on June 5. In August 2019, the head of the Coliseum Authority, Scott McKibben, abruptly resigned his position after allegations emerged that he had requested a $50,000 fee from RingCentral in exchange for negotiating the naming rights deal. McKibben was subsequently charged by the Alameda County district attorney's office with violating conflict-of-interest laws, including one felony and one misdemeanor count. On January 17, 2020, the RingCentral naming rights deal was rescinded by the Coliseum Authority. In late 2020, a new three year naming rights deal with RingCentral was agreed to.

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. This, combined with the hill that was built around the stadium to create the upper concourse, means that only the third deck is visible from outside the park. Configurations In its baseball configuration, the Coliseum has the most foul territory of any ballpark in Major League Baseball. Thus, many balls that would reach the seats in other ballparks can be caught for outs at the Coliseum. The distance to the backstop was initially , but was reduced to in 1969. From 1968 through 1981 and in 1995, two football configurations were used at the stadium. During Raider preseason games and all regular season games played while the baseball season was still going on, the field was set up from home plate to center field (east/west). Seats that were down the foul lines for baseball games became the sideline seats
