Daniel Vallejo and Gael Monfils meet in the first round at US Open on Tuesday. Gael Monfils has dropped 2 straight and sits at 4-6 over the last ten. Daniel Vallejo is searching for form, having lost 2 in a row (5 of the last 10).
Monfils's 70.8% behind the first serve (against 64.9% for Vallejo) means break chances should be scarce in one direction. A tiebreak or two would surprise nobody, with Monfils fractionally more likely to land the big points.
