Sloane Stephens has won both her previous meetings against Yulia Putintseva. She needed three sets to beat the WTA World No.93 in last year's Canadian Open, though.
Kateryna Bondarenko has already enjoyed clay court success over Heather Watson, beating the Brit in Strasbourg in 2016, 6-3, 0-6, 6-1.
Watson is aiming to snap an eight-match losing streak dating back to the semifinals of Hobart.
Andrea Petkovic and Sorana Cirstea have never previously met. The German was the runner-up in Nurnberg in 2013, when she lost in the final to Simona Halep.
Christina McHale has a 1-0 career head-to-head record against Johanna Larsson. Their only main draw meeting previously was at Wimbledon in 2015, but they have since met in Doha qualifying - a match also won by the American.
