Quick Take

Pre-match view

Context last updated 19 Jul 2026, 23:28 · Europe/Bucharest

Costoulas is favored after a straight-sets qualifying win over Aksu and a 3-1 H2H lead, but Aksu's competitive hard-court form makes a close match likely.

Best bets include Aksu +4.5 games, over 9.5 games in set one, and over 7.5 total double faults.

- She then played Aksu on July 19, winning in straight sets but still expending energy.
- Aksu also played on both days, but her July 18 win was a quicker 6-3, 6-3 victory.
Aksu has 70 double faults in her last 15 matches (4.7 per match).
