A spot in the next round is at stake on Thursday, when Gael Monfils goes up against Learner Tien in the Montreal round of 64. Learner Tien is searching for form, having lost 2 in a row (6 of the last 10). Gael Monfils is 4-6 across recent matches.
Learner Tien simply rates much higher on hard, and our number follows from it. A tiebreak or two would surprise nobody, with Tien fractionally more likely to land the big points.
