What milestone did Taylor Townsend and Kateřina Siniaková complete at the 2026 US Open?
Answer
A career Grand Slam
Taylor Townsend and Kateřina Siniaková completed a career Grand Slam at the 2026 US Open.
They achieved the milestone by winning the women’s doubles championship in New York. A career Grand Slam means winning the Australian Open, French Open, Wimbledon, and US Open at least once during a career; it does not require winning them in the same calendar year.
The pair had previously won Wimbledon in 2024, the Australian Open in 2025, and the French Open in 2026. Their US Open victory over Ashlyn Krueger and Robin Montgomery supplied the only missing major title in their partnership record.
This achievement is different from a calendar-year Grand Slam, which requires winning all four majors in one season. It is also different from a Golden Slam, which adds an Olympic gold medal. Siniaková had already achieved major doubles success with other partners, but the 2026 result completed the four-event sequence with Townsend.
