To scribe their names onto the roll of honour they’ll have to topple the defending champions Timea Babos and Kristina Mladenovic on Sunday.
Guarachi, who has battled back from a career-threatening ACL injury five years ago, is a product of the US college tennis system and so is her partner Krawczyk.
The likes of US Open semi-finalist Jennifer Brady and Roland-Garros quarter-finalist Danielle Collins have also taken the college tennis route, emphasising the benefits of that path to the top.
“I think there are a ton of us that are rising in the rankings and doing well. For me personally college was the perfect route, especially in doubles,” explained the 26-year-old Krawczyk, who played for Arizona State University.
“I learned so much, how to really be a team player, how to enjoy myself out there. I think it’s definitely helped me raise my level and to be able to play with different players.”
The signs for success in Paris were there last month. An early exit at the US Open prompted a last-minute trip to Turkey, where the duo lifted the trophy on the clay in Istanbul to propel themselves into title contention in the French capital.
