1. Begin outside New York
The men's national championship began at the Newport Casino in Rhode Island. Its early entry conditions were tied to clubs belonging to the national tennis association. Richard Sears dominated that opening chapter. The women's championship developed separately at the Philadelphia Cricket Club, rather than starting as another draw at the same Newport event.
This separate geography matters. A combined list of national champions can make the early tournament look more unified than it was. Check the discipline and venue attached to each result. Men's singles, women's singles and doubles competitions did not always share a site or the same path towards consolidation.
2. Find the Forest Hills chapter
The West Side Tennis Club at Forest Hills became a principal home of the championships, although the men's singles also spent an intervening period at the Germantown Cricket Club in Philadelphia. The route from Newport to New York was therefore not a single uninterrupted move.
Forest Hills hosted the first US Open after the admission of professionals. Arthur Ashe won the men's singles and Virginia Wade won the women's singles at that inaugural open edition. “US National Championships” and “US Open” mark an eligibility transition within the event's history, rather than two unrelated competitions whose records should never be connected.
3. Track all three surfaces
The championship was played on grass before Forest Hills adopted green clay. The later move to Flushing Meadows brought hard courts. Green clay, often associated with Har-Tru, differs in material from the red clay at Roland-Garros. Grouping both under “clay” can be useful, but it should not imply that their playing characteristics are identical.
Jimmy Connors won US singles titles on grass, clay and hard courts. That established achievement makes him a particularly clear example of success across the tournament's surface changes. It also shows why a US title total cannot automatically be described as a hard-court total: earlier editions require their own surface labels.
4. Understand the Flushing Meadows move
The relocation to the National Tennis Center in Flushing Meadows gave the competition a different setting from the private-club environment at Forest Hills. The complex in Queens developed around a larger public-facing tournament, with expanded spectator facilities and a succession of changes to its show courts.
The venue later received the name USTA Billie Jean King National Tennis Center. Arthur Ashe Stadium became its principal stadium, while Louis Armstrong Stadium belongs to both an earlier structure and a replacement bearing the same name. When locating an old match, identify the relevant stadium period rather than relying on a familiar name alone.
5. Read innovations as separate decisions
The US Open was the first major to introduce the tiebreak. A tiebreak is a points-based procedure used to decide a set once a specified game score has been reached. Its early format differed from later versions, so an old reference to a tiebreak should not automatically be read using modern scoring assumptions.
The tournament also became the first major to award equal prize money to men and women. Billie Jean King's advocacy is central to that history. This was a decision about championship remuneration; it should not be expanded into a claim that every part of professional tennis became financially equal at the same moment.
6. Compare the right kind of record
Night sessions, stadium expansion and changes to scoring all affected the event's presentation and operation. They are distinct from a player's achievement on court. If you want to compare champions, begin with a defined category such as women's singles in the Open Era or men's titles at Forest Hills.
Then ask what changed inside that category. Chris Evert's US championship record spans the clay and hard-court chapters, while later champions competed entirely within the hard-court period. The official archive lets you connect a title to a draw, venue and surface. That is a stronger foundation than treating every edition as an identical test.
