Lehecka vs Vallejo Prediction 4 October 2026
🔊 Adolfo Daniel Vallejo is playing his first ATP 500 tournament and has already reached the quarter-finals in Tokyo, where he faces Jiří Lehečka. Although the Paraguayan has played two more matches than his Czech opponent, his path through the main draw has been considerably smoother - Lehečka has played three-setters in consecutive matches. Meanwhile, Vallejo has yet to drop a set, with two upsets to his name along the way: victories over current and former top players Rafael Jodar and Matteo Berrettini. Let's assess Adolfo Daniel's chances of another upset.
Head-to-Head
📊 Jiří Lehečka and Adolfo Daniel Vallejo have no previous meetings on record.
Jiri Lehecka Player Overview
Jiri Lehecka enters the quarter-final as the favourite by ranking and odds, and carries a four-match winning streak this autumn that began at the Davis Cup with victories over Ben Shelton (6-4, 6-4) and Learner Tien (6-3, 7-5). His path in Tokyo has not been straightforward, though - he has gone the distance in both rounds so far, against Zizou Bergs (6-3, 6-7, 6-3) and Ugo Humbert (5-7, 6-4, 6-4). Lehecka has a varied and powerful serve that regularly earns him easy points. In rallies he prefers to play from the baseline, which he covers fully thanks to his quick first step, hitting through opponents with flat, penetrating two-handed groundstrokes.
Match Results: Jiri Lehecka
Adolfo Daniel Vallejo Player Overview
Adolfo Daniel Vallejo is also on a four-match winning streak, though entirely within the current tournament, which he entered through qualifying, dropping just one set along the way. In the main draw, despite a noticeably higher level of opposition, Vallejo has posted two straight-sets wins - over world No. 13 Rafael Jodar (6-1, 6-3) and former world No. 6 Matteo Berrettini (7-6, 6-1). The Paraguayan does not have as powerful a serve as Lehecka, but is extremely tenacious on return, converting around 40% of his break points. He also prefers to play from the baseline but does not look to finish rallies in two or three shots, though he uses both hands equally effectively.

Key factors
- Adolfo Daniel Vallejo has won more than 11.5 games in eight matches in a row.
- Adolfo Daniel Vallejo's matches average 26.3 games.
- Both players are on four-match winning streaks, but Jiří Lehečka has played two consecutive three-set matches.
Expected scenario
Jiří Lehečka will take on the aggressor's role from the opening games, looking to dictate play with a powerful first serve and flat, aggressive groundstrokes from the baseline. A confident Adolfo Daniel Vallejo will play the counter-puncher, becoming a near-impenetrable wall. The Paraguayan will deliberately extend rallies to draw the Czech into a run of unforced errors, which are likely to mount given the more aggressive style and physical fatigue from two gruelling three-set matches in the Tokyo main draw.
Total Games Prediction
A lengthy run of Vallejo's individual total going over the line suggests he consistently maintains a high level of game output regardless of the opponent's quality, something particularly evident in his two previous matches in the Japanese capital. This is relevant ahead of the match against Lehecka, who has dropped a set in each of his last two rounds, against lower-ranked opponents.
⭐ Editor's Pick
Both players are in winning streaks, though with one difference: Adolfo Daniel Vallejo has not dropped a set in his last two matches, while Jiří Lehečka has been going the distance in three-setters on the Japanese courts. Lehečka's consistency will be the key factor - and so far in Tokyo there has been little sign of it. That said, if the Czech's attacking shots stay free of unforced-error runs, he should have enough class to close out his opponent. Vallejo, for his part, has paid no attention to his opponents' status throughout this 500-level event, so there is little doubt he will make it a contest against another top player. We suggest taking advantage of his underdog status with Vallejo - Games Handicap +4.5.
