Quick Take

Pre-match view

Context last updated 2 Sep 2026, 03:31 · Europe/Bucharest

Ivashka's superior recent form and serve/return stats make him the likely winner, but the 1.29 odds overestimate his chances.

Santillan's hard-court comfort and Ivashka's low first-serve percentage create upset potential. Betting value lies in over 21.5 total games and possibly over 7.5 aces, while avoiding the match winner market.

Context

Ivashka, 32, is a former top-50 player now ranked 393 and rebuilding on the Challenger tour. Santillan, 29, is ranked 331 and has a one-handed backhand.
Ivashka's 73.3% win rate in the last 15 matches, all on hard courts, includes wins over players ranked inside the top 250. Santillan's 60% hard-court record in the same window is decent but includes losses to players ranked 528 and 356. This suggests Ivashka has been more consistent against similar opposition, though Santillan's recent win over Omar Jasika shows he can compete.
- Ivashka last 15 overall record: 11-4 (73.3%), all on hard courts.
- Santillan last 10 hard-court record: 6-4 (60%), with losses to Sanhui Shin (rank 528) and Antoine Ghibaudo (rank 356).
- Ivashka's recent wins include Yi Zhou (rank 248) and Ergi Kirkin (rank 657).
Ivashka's game is built on a strong first serve and solid baseline play. Santillan relies on his one-handed backhand and can be aggressive but has been less consistent on serve.
Ivashka wins 75.1% of first-serve points and 57.2% of second-serve points, compared to Santillan's 70.6% and 47.6%. Ivashka also wins 41.1% of return points versus Santillan's 36.7%. These gaps suggest Ivashka can hold serve more comfortably and create more pressure on Santillan's serve, though Santillan's higher first-serve percentage (62.6% vs 58.6%) may help him stay in rallies.
- Ivashka first-serve points won: 75.1% vs Santillan 70.6%.
- Ivashka second-serve points won: 57.2% vs Santillan 47.6%.
- Ivashka return points won: 41.1% vs Santillan 36.7%.
- Santillan first-serve in: 62.6% vs Ivashka 58.6%.
Santillan's one-handed backhand can produce winners but also leads to more errors under pressure. His second serve has been a vulnerability.
Santillan's 2.9 double faults per match on hard courts is higher than Ivashka's 3.3 overall, but Ivashka's double faults are spread across all surfaces. On hard courts, Santillan's second-serve points won is only 51.3%, so if he misses first serves, Ivashka can attack. This could lead to break opportunities for Ivashka, especially in tight games.
- Santillan hard-court double faults per match: 2.9 (last 10 matches).
- Santillan hard-court second-serve points won: 51.3%.
- Ivashka overall double faults per match: 3.3 (last 15 matches).
Ivashka needed 2:18:26 to beat Yi Zhou in three sets, while Santillan finished his opener in 1:37:56. Ivashka enters this match after a longer first-round workload, but the extra 40 minutes is unlikely to be decisive in a best-of-three Challenger match.
- Santillan completed his opening match in straight sets, while Ivashka played a three-set match lasting 40 minutes longer.
