In a battle of the top two seeds and former French Open champions, it was the second-seeded Latvian who came out on top, winning 7-6 (8), 6-4.
Krejcikova hadn’t dropped a set all week coming into the championship match. But it was Ostapenko who secured a tight opening set at her fourth opportunity in the tiebreaker.
Ostapenko then raced to a 5-1 lead to leave her on the brink of victory before Krejcikova responded by winning three games in a row.
“I was really close from 5-1 to 5-4 but then I managed somehow and I’m really, really happy about it,” said Ostapenko, who had four three-set matches before the final.
“I was fighting every match. I played five great matches, this was the only match in two sets. It’s a great preparation for Wimbledon and there’s still a couple of things I can do better.”
It was Ostapenko’s sixth singles title and her second on grass after triumphing at Eastbourne in 2021.
