A spot in the next round is at stake on Wednesday, when Daniel Altmaier goes up against Zachary Svajda in the US Open first round. Daniel Altmaier comes in at 5 wins from the last ten. Zachary Svajda is searching for form, having lost 4 in a row (4 of the last 10).

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. A tiebreak or two would surprise nobody, with Altmaier fractionally more likely to land the big points.
