7 matches are on Saturday's card at US Open, and we have a pick for every one of them. The headline act: Alexander Blockx against Flavio Cobolli in the round of 32. Our calls: Cobolli over Blockx, Shelton over Shapovalov, Fritz over Cerundolo, Zandschulp over Bergs, Gea over Zheng, Khachanov over Bonzi, and 1 more.

The boldest call on the card: Gea over Zheng — the market disagrees with us there.

Ben Shelton vs. Denis Shapovalov

✓ Pick rightNailed it. We had Ben Shelton at 69% before the match, and Ben Shelton won 7-6 6-7 6-3 6-4.

Pick: Shelton

Win probability: 69% Shelton · Market: -321 · Sets: 4+ (58%) · most likely score 3-0 (34%)

A spot in the next round is at stake on Saturday, when Ben Shelton goes up against Denis Shapovalov in the US Open round of 32. Ben Shelton comes in at 8 wins from the last ten. Denis Shapovalov comes in at 7 wins from the last ten.

There's a wide gap in our ratings on hard, and our number follows from it. Expect resistance, but the match-level math tilts clearly toward Shelton.

Dane Sweeny vs. Luciano Darderi

✓ Pick rightNailed it. We had Luciano Darderi at 72% before the match, and Luciano Darderi won 6-4 6-3 6-3.

Pick: Darderi

Win probability: 72% Darderi · Market: -330 · Sets: 3 (51%) · most likely score 3-0 (40%)

Saturday's US Open round of 32 pits Dane Sweeny against Luciano Darderi on hard. Luciano Darderi has won 6 of the last 10. Dane Sweeny has won 5 of the last 10.

Hold strength tells the story — 69.9% versus 66.2% on first-serve points in Darderi's favor. Anything other than a Darderi win would rank among the bigger surprises of the week.

Francisco Cerundolo vs. Taylor Fritz

✗ Pick wrongWe got this one wrong. Our final number was 67% on Taylor Fritz; Francisco Cerundolo won 3-6 4-6 6-3 6-4 6-4.

Pick: Fritz

Win probability: 67% Fritz · Market: -500 · Sets: 4+ (59%) · most likely score 3-0 (31%)

A spot in the next round is at stake on Saturday, when Francisco Cerundolo goes up against Taylor Fritz in the US Open round of 32. Taylor Fritz has won 8 of the last 10. Francisco Cerundolo has won 6 of the last 10.

The serve is where this match separates: Fritz has been winning 74.6% of first-serve points to Cerundolo's 66.8%, and on hard that gap compounds fast. Expect resistance, but the match-level math tilts clearly toward Fritz.

Arthur Gea vs. Michael Zheng

✓ Pick rightNailed it. We had Arthur Gea at 60% before the match, and Arthur Gea won 7-6 3-6 4-6 6-3 6-2.

Pick: GeaUpset call

Upset call: the market makes Zheng the favorite; our numbers say Gea.

Win probability: 60% Gea · Market: +140 · Sets: 4+ (76%) · most likely score 3-1 (25%)

Saturday's US Open round of 32 pits Arthur Gea against Michael Zheng on hard. Arthur Gea has won 6 in a row and 9 of the last 10 overall. Michael Zheng comes in at 6 wins from the last ten.

Arthur Gea simply rates much higher on hard, and our number follows from it. Expect resistance, but the match-level math tilts clearly toward Gea.

Botic Van De Zandschulp vs. Zizou Bergs

✓ Pick rightThis one lands on the correct side of the ledger: 51% on Botic Van De Zandschulp, who won 3-6 7-6 4-6 7-6 6-3.

Pick: Zandschulp

Win probability: 51% Zandschulp · Market: -194 · Sets: 4+ (65%) · most likely score 3-1 (19%)

Saturday's US Open round of 32 pits Botic Van De Zandschulp against Zizou Bergs on hard. Botic Van De Zandschulp has won 7 of the last 10. Zizou Bergs comes in at 6 wins from the last ten.

Botic Van De Zandschulp is clearly higher-rated on hard — our number puts Zandschulp around 51%. Little separates them; Zandschulp gets the nod on the finest of margins.

Alexander Blockx vs. Flavio Cobolli

✗ Pick wrongMissed it. We had Flavio Cobolli at 51%, but Alexander Blockx won 6-7 6-3 6-0 6-3.

Pick: Cobolli

Win probability: 51% Cobolli · Market: -102 · Sets: 4+ (69%) · most likely score 3-1 (21%)

A spot in the next round is at stake on Saturday, when Alexander Blockx goes up against Flavio Cobolli in the US Open round of 32. Flavio Cobolli has won 6 of the last 10. Alexander Blockx has won 5 of the last 10.

The underlying stats are tight across the board — this is a matchup decided by a handful of points. This one is close to a coin flip, and the lean toward Cobolli is exactly that — a lean.

Benjamin Bonzi vs. Karen Khachanov

✓ Pick rightThis one lands on the correct side of the ledger: 51% on Karen Khachanov, who won 6-3 6-2 6-4.

Pick: KhachanovUpset call

Upset call: the market favors Bonzi; our numbers say Khachanov.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. Little separates them; Khachanov gets the nod on the finest of margins.
