Jessica Pegula is back to defend her Canadian Open title in 2025, and could join a historic WTA 1000 club with victory this year.

Having lifted the title in 2023 and 2024, the world No 4 is looking to complete a ‘threepeat’ of titles in 2025.

Since the WTA 1000/Tier 1 format was first introduced in 1990, only five women have ever won 3+ straight titles at the same Premier event.

Here, we look at the legendary company Pegula will look to join over the next week.

Steffi Graf – Miami Open, Berlin OpenOne of the greatest players to ever pick up a racket, former world

No 1 Graf won 3+ straight titles at both the Miami Open and Berlin Open during her career.

Graf won three straight Miami Open titles from 1994 to 1996, defeating Natasha Zvereva, Kimiko Date, and Chanda Rubin to triumph in all three seasons.

Having won four straight Berlin titles before the Tier 1 format was introduced, Graf then again won four consecutive titles from 1991-94.
