Wong vs Vallejo Prediction 26 September 2026
🔊 Chak Lam Coleman Wong has reached the second round, matching his best result of 2024 at the ATP 250 in Hangzhou. He now faces fifth seed Adolfo Daniel Vallejo, who is making his debut at this tournament. The two players arrive with contrasting recent form: the Paraguayan only ended a losing streak upon arriving in China, while the Hong Kong player had been picking up wins consistently in qualifying for main-draw events and on the Challenger circuit. As a result, it is the lower-ranked Asian player who is the bookmakers' favourite. The question is whether he can live up to that billing.
Head-to-Head
📊 Chak Lam Coleman Wong and Adolfo Daniel Vallejo have no previous meetings on record.
Chak Lam Coleman Wong Player Overview
Chak Lam Coleman Wong is in decent form - seven wins from his last ten matches reflect a consistent run of results. At the start of the Hangzhou event he beat Zhizhen Zhang comfortably, 6-3, 6-3, and has generally produced solid results for a player ranked outside the top 100, even breaking into the top 100 for a period thanks to qualifying runs at major tournaments including Cincinnati and the US Open, as well as reaching the semi-finals of an ATP 250 in Los Cabos. His strengths include a high sets-won percentage (64%) and a good hold rate. Wong also tends to take control early in matches, having won the first set in six of his last seven.
Match Results: Chak Lam Coleman Wong
Adolfo Daniel Vallejo Player Overview
Adolfo Daniel Vallejo has won 5 of his last 10 matches, pointing to inconsistent form. Recent results have been mixed: there were wins over top-40 player Ignacio Buse in the Davis Cup (5-7, 7-5, 7-6) and over Jie Cui in the first round in Hangzhou (6-1, 6-7, 6-4), but heading into the current tournament the Paraguayan had lost three in a row. His best result on the summer hard-court swing was reaching the round of 16 in Cincinnati. His sets-won percentage (46%) is noticeably lower than his upcoming opponent's, and his games-won percentage is also below - just 47%. On serve, Vallejo has not dominated either, as reflected in a slight but visible gap in hold percentage compared with Colman Wong - 77% against 78%.

Key factors
- Chak Lam Coleman Wong has won 7 of his last 10 matches.
- Chak Lam Coleman Wong's set-winning percentage is 64%, compared to 46% for his opponent.
- In recent matches, Chak Lam Coleman Wong has shown a high percentage of games won.
Expected scenario
Despite sitting lower in the rankings, Chak Lam Coleman Wong looks the favourite here, on the back of more consistent form and a higher percentage of sets and games won. Adolfo Daniel Vallejo has the quality to make things competitive, so close sets are possible. That said, the Hong Kong player's more dominant style - particularly on serve - suits the fast hard courts in Chengdu, and he also spent less energy in the first round than the Paraguayan.
⭐ Editor's Pick
Chak Lam Coleman Wong is in noticeably better form: seven wins with a high set-winning percentage support his advantage ahead of the second round, which is reflected in the odds. He consistently starts matches strongly and wins games more often on both serve and return. Even if Adolfo Daniel Vallejo manages to compete in individual sets, the overall level of the higher-ranked Asian player is currently superior. With that in mind, we side with the bookmakers and back Coleman Wong to Win.
