Top seed Stan Wawrinka headlines second round action in Marseille on Wednesday, with no. 4 seed Marin Cilic and Belgium's David Goffin also in the mix.
Playing for the first time since a shock Australian Open fourth round exit, Wawrinka will be hoping to return to his winning ways in Marseille. Benefiting from a first round bye, the Swiss no. 2 opens his title campaign against Sergiy Stakhovsky – who infamously beat Wawrinka's compatriot Roger Federer at Wimbledon a few years ago. That is not the only scalp the Ukrainian has achieved, and one of them came against Wawrinka himself. Not only that, but it was right here in Marseillelast year. After Stan Wawrinka began their rivalry on the more positive note with a 6-7(6) 7-6(2) 6-4 6-2 win at the 2012 US Open, Stakhovsky rebounded for a 6-4 3-6 6-4 victory in the 2015 Marseille quarterfinals. Without a doubt, the world no. 4 will be on his guard when he takes to Court Central on Wednesday in France.
No. 4 seed Marin Cilic will be following him on, the former US Open champion scheduled to take on Robin Haase in Court Central's last match of the day. Cilic has had a mediocre start to the year, with an especially disappointing third round showing at the Australian Open, but carries a 4-0 head-to-head record into his encounter with 28-year-old Haase. The two have played their last three meetings on clay, however, and Robin Haase puched the Croat to go the distance in their only hard-court encounter.
David Goffin is the only other singles seed in action on Wednesday, and will kick off play on Court Central. The Belgian completed an impressive 6-3 6-1 win over fast-rising South Korean Hyeon Chung in the first round here, setting him up for another dangerous clash. Mischa Zverev – older brother of uprising Alexander Zverev – qualified for the event in Marseille, and also scored a 6-3 6-1 win in round one. He leads his head-to-head with David Goffin by one win to none, having beaten him 1-6 6-4 7-5 on the grass of Halle in 2013.
Two all-French clashes are also set to delight the Court Central crowds on Wednesday, with Rotterdam semifinalist Nicolas Mahut taking on world no. 196 Vincent Millot, and 19-year-old Quentin Halys facing David Guez, 33, in a battle of youth and experience.
