3 matches are on Monday's card at US Open, and we have a pick for every one of them. The headline act: Arthur Gea against Botic Van De Zandschulp in the round of 16. Our calls: Gea over Zandschulp, Blockx over Cerundolo, Tien over Khachanov.

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

Karen Khachanov vs. Learner Tien

✗ Pick wrongA miss: Learner Tien at 61% lost to Karen Khachanov (7-5 4-6 6-7 6-1 6-4).

Pick: Tien

Win probability: 61% Tien · Market: -167 · Sets: 4+ (64%) · most likely score 3-0 (23%)

Karen Khachanov and Learner Tien meet in the round of 16 at US Open on Monday. Learner Tien comes in at 7 wins from the last ten. Karen Khachanov is rolling — 3 straight wins, 5 of 10 in recent play.

There's a wide gap in our ratings on hard, and our number follows from it. The edge belongs to Tien — real, but not the kind you take for granted at this level.

Alexander Blockx vs. Francisco Cerundolo

✓ Pick rightNailed it. We had Alexander Blockx at 55% before the match, and Alexander Blockx won 6-3 4-6 7-5 7-5.

Pick: Blockx

Win probability: 55% Blockx · Market: -147 · Sets: 4+ (74%) · most likely score 3-1 (21%)

Monday's US Open round of 16 pits Alexander Blockx against Francisco Cerundolo on hard. Alexander Blockx comes in at 6 wins from the last ten. Francisco Cerundolo has won 6 of the last 10.

Blockx's 74.8% behind the first serve (against 66.8% for Cerundolo) means break chances should be scarce in one direction. This one is close to a coin flip, and the lean toward Blockx is exactly that — a lean.

Arthur Gea vs. Botic Van De Zandschulp

✗ Pick wrongA miss: Arthur Gea at 54% lost to Botic Van De Zandschulp (3-6 6-7 7-6 7-6 6-4).

Arthur Gea simply rates much higher on hard, and our number follows from it. This one is close to a coin flip, and the lean toward Gea is exactly that — a lean.
