The U.S. Open first round is the day's main attraction, with the men's and women's draws in action from early to late.
The U.S. Open is the centrepiece of the day. Both the ATP and WTA draws are in their first round in New York, with most of the singles fields still to play. A handful of Challenger events are also on the schedule, on hard courts and clay.
The matches the model rates highest are spread through the day, from the early session into the evening. The picks it calls near-even are among the more interesting openers on the card. Earlier, the tournaments in Winston-Salem and Monterrey finished for the day.
In Canada, TSN and RDS are the home of the US Open. Challenger matches are on Challenger TV.

Model: 79% M. Andreeva · 21% J. Tjen
M. Andreeva is favoured by the model, but J. Tjen is ranked closely enough to make this a genuine test. It is a first-round match with more substance than the usual opener.
Model: 66% I. Jović · 34% M. Frech
I. Jović is the model's pick and holds the higher ranking. M. Frech is the outsider, but the gap is not enormous and this should be a watchable contest.
Model: 37% D. Snigur · 63% D. Shnaider
D. Shnaider is slightly favoured, yet D. Snigur is close enough to keep the match alive. Another of the day's tighter first-round calls.
Model: 28% A. Fery · 72% L. Musetti
L. Musetti is the clear model's pick and the higher-ranked player. A. Fery will need to produce more than expected to turn the match around.
Model: 33% N. Borges · 67% L. Tien
L. Tien is the model's pick and the higher-ranked player. N. Borges is the underdog and will have to find something extra to compete.
Model: 46% A. Potapova · 54% T. Valentová
The model splits this match almost down the middle, making it one of the closest calls of the day.
Model: 72% B. Shelton · 28% T. Griekspoor
B. Shelton is the model's pick and a clear favourite. T. Griekspoor is ranked behind and starts with the underdog's role.
Model: 47% Y. Hanfmann · 53% A. Tabilo
Y. Hanfmann and A. Tabilo are another near-even pairing for the model, with neither side holding a meaningful edge. The match should be tight and competitive.
The first round of a Grand Slam is the stage where the draw is at its most open, and today's card reflects that.
