Arthur Fils vs Valentin Vacherot

Pick: Fils

Win probability: 65% Fils · Market: -336 · We call it in 2 sets (62%) · single likeliest score 2-0 (41%)

Arthur Fils and Valentin Vacherot meet in the quarterfinal at Tokyo on Sunday. Arthur Fils comes in at 8 wins from the last ten. Valentin Vacherot is 6-4 across recent matches.

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

Jaume Munar vs Kyrian Jacquet

✗ Pick wrongMissed it. We had Kyrian Jacquet at 52%, but Jaume Munar won 6-4 6-2.

Pick: Jacquet

Win probability: 52% Jacquet · Market: +139 · We call it in 3 sets (48%) · single likeliest score 2-0 (26%)

Sunday's Tokyo quarterfinal pits Jaume Munar against Kyrian Jacquet on hard. Kyrian Jacquet comes in at 6 wins from the last ten. Jaume Munar is 6-4 across recent matches.

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

Carlos Alcaraz vs Denis Shapovalov

Not gradedThis match ended in a retirement, advancing Carlos Alcaraz. It is excluded from our graded record — no pick is counted as right or wrong.

Pick: Alcaraz

Win probability: 81% Alcaraz · Market: -615 · We call it in 2 sets (69%) · single likeliest score 2-0 (59%)

A spot in the next round is at stake on Sunday, when Carlos Alcaraz goes up against Denis Shapovalov in the Tokyo quarterfinal. Carlos Alcaraz comes in at 8 wins from the last ten. Denis Shapovalov is 7-3 across recent matches.

Carlos Alcaraz simply rates much higher on hard, and our number follows from it. Shapovalov needs several things to break right at once; the percentages say they usually don't.

Daniel Vallejo vs Jiri Lehecka

✓ Pick rightThis one lands on the correct side of the ledger: 74% on Jiri Lehecka, who won 6-1 6-1.

Pick: Lehecka

Win probability: 74% Lehecka · Market: -241 · We call it in 2 sets (62%) · single likeliest score 2-0 (48%)

Daniel Vallejo and Jiri Lehecka meet in the quarterfinal at Tokyo on Sunday. Jiri Lehecka brings a 3-match winning streak into this one, 7-3 across the last ten. Daniel Vallejo is 5-5 across recent matches.

Lehecka's 73.1% behind the first serve (against 65.2% for Vallejo) means break chances should be scarce in one direction. Anything other than a Lehecka win would rank among the bigger surprises of the week.
