Boulter vs Vekic Prediction 13 June 2026
🔊 Katie Boulter pulled off the biggest upset of her home tournament in London, knocking out world No. 2 Elena Rybakina in the quarterfinals. In the semifinals, the level of opposition drops noticeably, as she faces world No. 76 Donna Vekic. Still, the Croatian shouldn’t be underestimated-she owns a grass-court title herself, having triumphed in Nottingham. Even so, Boulter holds the edge with twice as many trophies on this surface. Can Vekic pose a real challenge to the local favorite?
Head-to-Head
📊 Katie Boulter hold the edge in their head-to-head, leading 2-0. Their most recent encounter took place on hard courts in San Diego, where Boulter secured a straight-sets victory.

Katie Boulter Player Overview
Katie Boulter is enjoying a strong stretch this season, having picked up six wins in her last ten matches and stringing together three straight victories in London, including a hard-fought quarterfinal against Elena Rybakina (7-5, 2-6, 6-4). Interestingly, Boulter had to work even harder in the opening round against the less heralded Leylah Fernandez (3-6, 7-6, 7-5), who nonetheless ranks inside the world’s top 30. Clearly, the level of opposition for the Brit has been formidable. On serve, Boulter wins 69% of her points, even though her first-serve accuracy sits at a modest 65%. However, she more than makes up for it with her return game, regularly converting break points at an impressive 43% rate.

Donna Vekic Player Overview
Donna Vekic is also enjoying a strong run of form, having claimed seven wins in her last ten matches. Notably, she reached the main draw of the WTA 500 event in London as a lucky loser, after falling short in the qualifiers. Compared to Boulter's path, the draw has certainly favoured the Croatian: she faced two players ranked outside the top 100 (Stojsavljevic and Pliskova), along with world No. 28 Marie Bouzkova. Vekic boasts an impressive 67% set-winning rate and consistently converts 47% of her break point opportunities. On serve, Donna wins 64% of her points, although her first-serve accuracy lags behind at 63%.

Key factors
- Seven of Katie Boulter’s last eight matches have featured over 22.5 games.
- Both players are in strong form and consistently pick up sets.
- Boulter’s matches average 26 games, while Vekic’s come in at 19.5.
- Their stats for sets and games won are closely matched, suggesting a high probability of a lengthy contest.
Expected scenario
The clash between Katie Boulter and Donna Vekic promises a high game count, with both players coming into the match in strong form and posting similar records in sets and matches won. An important factor to consider is that Vekic finished her previous match later, so fatigue could play a role for her this time. While Vekic are seen as the favourites heading into this encounter, a straightforward win is far from guaranteed.
⭐ Editorial Prediction
Both players come into this match in solid form, each navigating the main draw in London with confidence. Vekic did stumble during the qualifiers, failing to advance directly, but has since recovered her composure. Their stats for sets won and service holds are nearly identical, highlighting how evenly matched they are. With neither player dominating the key metrics, this semi-final looks set to be a tightly contested battle rather than a one-sided affair from the favorite.It’s also worth noting that Katie’s previous match wrapped up in the final slot yesterday and ran so late that the last quarter-final against her compatriot Raducanu couldn’t even be played. While it would be foolish to downplay the Brit’s edge-both in terms of grass-court pedigree and her performances at this tournament-this won’t be a walk in the park for her. We’ll take a cautious approach and back Boulter -1.5 games on the handicap.
