Damm beats Medvedev in straight sets at Winston-Salem
Martin Damm produced the upset of the Winston-Salem round of 32, taking out Daniil Medvedev 7-5, 6-3 without dropping a set. The American's first delivery was close to untouchable: he landed only 54.5 percent of them but won 86.1 percent of those points, and backed it up with 8 aces and 56.7 percent behind the second ball. Medvedev, by contrast, found just 45.6 percent of first serves and won 69.2 percent of them, leaving too many openings despite 10 aces. For Damm, it was a statement win over one of the game's elite returners.
