ATP tournament history
The San Diego Open was an ATP 250 tournament from 2021 until 2022. In August 2021, after the cancellation of the Asia Swing due to the COVID-19 pandemic, the Barnes Tennis Center was allocated a two-year 250 tournament license. Prior to that, it was exclusively a WTA event which was last held as a WTA Challenger in 2015 in Carlsbad, California.
Billie Jean King accepted the role of honorary tournament chairperson. Daniel Vallverdú took on the position of managing director. Ryan Redondo was named the tournament director.
In 2022, with the Asia swing still cancelled due to COVID, Vallverdú again instigated the collaboration between the ATP and the San Diego Barnes Tennis Centre which was then allocated a second one year 250 tournament license to be held post US Open 17–25 September.
