Cincinnati Open: A Guide to the Tournament

The Cincinnati Open is one of the most important stops on the North American hard-court season, bringing together the leading men's and women's players in the sport just weeks before the US Open. Held annually in the Cincinnati area, the Cincinnati Open tennis tournament has built a reputation as one of the toughest tests on the calendar heading into the year's final Grand Slam.

What Is the Cincinnati Open?

The Cincinnati Open is a combined professional tennis tournament held in the Cincinnati, Ohio area, featuring both men's and women's draws in the same week. The men compete at ATP Masters 1000 level and the women at WTA 1000 level, making it one of only a handful of events on either tour to host both top-tier fields simultaneously. It is played on outdoor hard courts as one of the final tune-ups before the US Open.

Why Is the Cincinnati Open Important in Professional Tennis?

The tournament's timing, prestige, and depth of field make it one of the most closely watched events of the summer.

A Major Stop Before the US Open

The Cincinnati Open is played on hard courts in the weeks immediately before the US Open, giving players their last major opportunity to test form, movement, and match sharpness on the same surface as the season's final Grand Slam.

Valuable ATP and WTA Ranking Points

As a Masters 1000 event on the ATP Tour and a WTA 1000 event on the WTA Tour, the Cincinnati Open offers some of the largest ranking-point rewards available outside the four majors, directly influencing US Open seeding.

A Strong Test Against Elite Fields

Because of its 1000-level status, the tournament typically draws much of the top of both tours, making deep runs in Cincinnati a genuine measure of which players are peaking at the right time.

One of Tennis's Historic US Tournaments

The Cincinnati Open dates back to 1899, making it one of the longest-running tennis tournaments in the world and the oldest US tournament still played in its original metropolitan area.

Cincinnati Open History and Evolution

The tournament has evolved considerably since its 19th-century origins.

The Tournament's Beginning in 1899

The event began in 1899, placing it among a small handful of tennis tournaments that have run continuously since the sport's early professional era in the United States.

Growth Into an ATP and WTA Event

Over the decades, the tournament grew from a regional competition into a combined stop hosting both the men's ATP Tour and the women's WTA Tour, with the women's event reaching WTA 1000-equivalent status in 2009.

Expansion of the Tournament Format

A $260 million campus transformation at the Lindner Family Tennis Center doubled the venue's footprint, allowing the tournament to expand to 96-player singles draws on both tours and a longer competition window running into late August.

Cincinnati Open Recognition and Growth

Following its 2025 edition, the Cincinnati Open was named ATP Masters 1000 Tournament of the Year, the first time the event has received this recognition, alongside WTA 1000 Tournament of the Year honors for the same season.

• Women's Singles and Doubles

The women's event carries WTA 1000 status, with a 96-player singles draw and a 32-team doubles draw contested alongside the men's event during the same fortnight.

Seedings are based on current rankings and are used to keep the leading players apart in the draw until later rounds, with some seeded players receiving opening-round byes under the tournament's expanded 96-player format.
