Fabian Marozsan vs James Duckworth — QF — Winston-Salem Open

The betting market made Marozsan a 60 percent pick, and the 15th seed leaves with his serve broken six times in 15 service games. Duckworth won 79 percent of his first-serve points to the Hungarian's 61, a split that stretched to 91 percent in a second set where he went 3 for 3 on break points. The third turned in game 9, a break for 5-4 after the two had traded breaks to open the set. Marozsan saved three match points before it closed at 2 hours 14 minutes, and the 34-year-old Australian moves on having dropped only the opening set all week, with wins over Navone and Sonego behind him.
