Tuesday's Montreal first round pits Pablo Carreno Busta against Valentin Royer on hard. Pablo Carreno Busta comes in at 6 wins from the last ten. Valentin Royer is searching for form, having lost 2 in a row (5 of the last 10).

Busta's 68.2% behind the first serve (against 26.1% for Royer) means break chances should be scarce in one direction. A tiebreak or two would surprise nobody, with Busta fractionally more likely to land the big points.
