How do they stack up?

Saturday will be the 11th career meeting between the two, with Swiatek leading the head-to-head record 7-3. Swiatek has won their past two meetings. 

Sabalenka's three wins have all gone a full three sets. Her most recent win came last year in the Madrid final, where she beat Swiatek on clay for the first time. This is the first time she has made back-to-back WTA 1000 finals in her career. 

In the past 40 years, only five duos have faced each other on more occasions as the World No.1 and No.2 than Swiatek and Sabalenka (5): Navratilova-Evert, Navratilova-Graf, Seles-Graf, Sanchez Vicario-Graf and Davenport-Hingis.

Since 1990, only Stefanie Graf and Arantxa Sanchez Vicario have faced each other more often in clay finals (10) than Swiatek and Sabalenka (5).

What milestones are at stake on Saturday?

Swiatek goes into Saturday's final leading the tour in match wins this season (37-4) and tied for the lead in titles with Elena Rybakina (3). She is bidding to win her fourth WTA 1000 of the season and 21st career title on the Hologic WTA Tour. 

Only two women have swept Madrid and Rome in a single season. Swiatek is bidding to become the third, joining Dinara Safina (2009) and Williams (2013). Only Williams has been able to win Madrid, Rome and Roland Garros in a single season. A win in Rome would put Swiatek in position to match the feat at Roland Garros where she is already a three-time champion. 

Swiatek could become the second player in the Open Era after Gabriela Sabatini to win three titles at the Italian Open before turning 23.

Sabalenka is the reigning Australian Open champion and bidding to win her second title of the season. Victory would deliver her a 15th career title. She is looking to join Rybakina as the only players to have beaten Swiatek twice on clay. If she does so, she would be the third player in the past four decades to beat the reigning No.1 in the final of Rome, joining Sabatini and Svitolina.

What are they saying?

Swiatek: "I think this match gave me confidence that I can win even though I'm not feeling the best way or I'm stressed at the beginning. I can still get the score back.

"Maybe I'm less worried before matches because I know even if I'm going to be in trouble, I'll be able to recover from it maybe if I'm going to work hard. This is the kind of feeling that I have."

Sabalenka: "After Madrid, I didn't feel great. I had illness, then I got injured. I was kind of surprised that with so much stuff going on I was able to make it to the final. Kind of surprised.

"At the same time I knew that the level is there. If I start feeling better, I can go to the finals."

Swiatek: "Honestly, I don't think it makes sense to think about these two matches [Madrid and Rome] as one continuing story because it's a totally different tournament. Well, different week, as well. It's not like it's going to be the same.

"I'll try to be in the present, not really think about Madrid. Obviously I need to analyze this match in terms of the tactics. Not too much, as well, because it was pretty tight. I think we both could have done some things better."

Sabalenka: "If I'm going to get to the point when I'm going to stay there with the match point, I'm going to go a little bit more aggressive. I'll just go. I'll trust myself and go for shots instead of trying to keep in the point, just keep the ball back in. Instead of play safe, I would just go for it.

"I think the level is there, the tennis is there, that I got everything to get this win. I just have to focus on myself, I guess, and not rush things, wait for the right shot to finish the point."
