Garbiñe Muguruza (ESP)  vs. Simona Halep (ROM) 
Simona Halep will replace Karolina Pliskova as World No.1 if she beats Garbiñe Muguruza on Sunday. She would be the first Romanian to top the rankings and the 24th woman overall.
Garbiñe Muguruza takes part in her first Cincinnati final - indeed, her first American final - while Simona Halep has reached the showpiece for the second time in three years. The Romanian was beaten by Serena Williams in straight sets two years ago.
Garbiñe Muguruza is the first Spaniard to ever make the Cincinnati final, whereas Simona Halep has followed in the footsteps of predecessor Magda Rurac, who won in 1949 before losing in both 1950 and 1951.
The last three finals have been won in straight sets, with the four before that all going to a third (2010-2013).
Garbiñe Muguruza hopes for a 39th match victory of 2017 - as Simona Halep seeks her 40th. Only Caroline Wozniacki (48), Elina Svitolina (45) and Karolina Pliskova (41) have more.
Both players are seeking a second WTA title of 2017 - Garbiñe Muguruza having won Wimbledon last month and Simona Halep already having won the Madrid crown.
Simona Halep has one win in the three previous meetings of the pair. The second seed prevailed on the Stuttgart clay in the pair's most recent meeting, in 2015 - following Garbiñe Muguruza's wins in Wuhan in 2014 and in the Fed Cup a year later - both on hardcourts.
Garbiñe Muguruza has dropped two sets on her way to the final - losing the second set in both her third round and quarterfinal victories over Maidson Keys and Svetlana Kuznetsova respectively. Simona Halep, however, is yet to drop a set in the tournament.
