US Open Series
series of tennis tournaments
The US Open Series was the name given by the United States Tennis Association (USTA) to a series of North American professional tennis tournaments leading up to and including the US Open. It was part of the "North American hard-court season".
History
The Series was initially organized in 2004 as a way to focus more attention on American tennis tournaments by getting more of them on domestic television. Until 2004, most summer North American tournaments were not on television, the exceptions being the prominent ATP Tour Masters 1000 events in Canada and Cincinnati. Since the inception of the series, Rafael Nadal is the only tennis player to win Canada, Cincinnati, and the US Open in a calendar year (2013), a feat referred to as the "Summer Slam" or the "North American Hardcourt Slam".
Since the Series' inception, North American tournaments have shifted in and out of the Series. In 2023, its final year, the Series was made up of six tournaments: Newport, Atlanta, Washington D.C., Winston-Salem, Cleveland, and the US Open itself. In 2024, the US Open Series website began redirecting to the US Open's official website, indicating the final end to the Series.
Under the US Open's broadcast rights, ESPN held domestic rights to all US Open Series events from 2015 to 2019. The eight non-Masters tournaments received about 50 hours of television combined – about two hours on each day of their final weekends, chiefly on ESPN2.

Why this record matters
“US Open Series” is worth following because a concise public description often conceals a longer documentary argument. Here, Series, series and tennis provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 5, 2026. The linked authority identifier is Q1193885. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2004, 1000, 2013 and 2023.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
