Ana gets her U.S. Open campaign underway on Monday when she takes on Slovakian world No.58 Dominika Cibulkova. The match will take place at 11am local time on Arthur Ashe Stadium, meaning it will be the tournament's first match on its marquee arena. Ana and Cibulkova have met four times before, with the head-to-head series tied at 2-2. Ana has won the last two meetings, including their only clash on outdoor hard courts, which occurred in Carlsbad two years ago. Cibulkova began the year ranked 10th but has been hampered by injury and missed four months of the season. She is in decent form, however, having beaten top 50-ranked players Sloane Stephens and Kristina Mladenovic during the past month.
