15 matches are on Sunday's card at US Open, and we have a pick for every one of them. The headline act: Toby Samuel against Tomas Machac in the first round. Our calls: Samuel over Machac, Djokovic over Navone, Atmane over Munar, Norrie over Assche, Medvedev over Gaston, Shapovalov over Kecmanovic, and 9 more.

Arthur Rinderknech vs. Sho Shimabukuro

✓ Pick rightThis one lands on the correct side of the ledger: 62% on Arthur Rinderknech, who won 6-7 6-2 7-6 6-2.

Pick: Rinderknech

Win probability: 62% Rinderknech · Market: -246 · Sets: 4+ (59%) · most likely score 3-0 (27%)

A spot in the next round is at stake on Sunday, when Arthur Rinderknech goes up against Sho Shimabukuro in the US Open first round. Arthur Rinderknech limps in on a 2-match losing skid, just 4 wins in 10. Sho Shimabukuro is searching for form, having lost 6 in a row (3 of the last 10).

Rinderknech's 74.8% behind the first serve (against 70.5% for Shimabukuro) means break chances should be scarce in one direction. The edge belongs to Rinderknech — real, but not the kind you take for granted at this level.

Jiri Lehecka vs. Pablo Carreno Busta

✓ Pick rightWe got this one right. Jiri Lehecka was our 62% pick, and won 6-1 7-6 4-6 6-2.

Lehecka's 72.7% behind the first serve (against 68.2% for Busta) means break chances should be scarce in one direction. Lehecka should have enough here, though Busta has the tools to make the scoreboard uncomfortable.
