Katie Boulter v Donna Vekic Prediction, Tips and Bet Builder

Katie Boulter will be hoping to make a memorable week even better when she takes on Donna Vekic in the semi-finals of the Queen's Club Championships on Saturday afternoon.

The British number three won two matches on Friday to book her spot in the last four, first overcoming Jaqueline Cristian in straight sets before claiming arguably the standout victory of her career when seeing off world number two Elena Rybakina 7-5, 2-6, 6-4.

A sixth WTA Tour level final is now within touching distance for the 29-year-old, but standing in her way is former Wimbledon semi-finalist Vekic, who has taken full advantage of earning a lucky loser spot following Marta Kostyuk's withdrawal from the tournament due to an ankle injury.

Vekic also had to come through two matches on Friday, as she followed a straight-sets victory over Marie Bouzkova with a hard-fought 6-4 4-6 6-3 win over former world number one Karolina Pliskova.

Katie Boulter v Donna Vekic Prediction

Best Bet: Katie Boulter to win @ 4/5

As far as Fridays go it was a pretty special one for Boulter, who needed just over an hour to see off Cristian before showing plenty of grit and determination, including saving 12 of the 14 break points she faced, to beat two-time Grand Slam winner Rybakina.

While those efforts may have taken a lot out of the word number 73, she will arguably be the fresher of the two players when she takes on Vekic, who spent 25 minutes longer on court on Friday with both her matches lasting over two hours.

Boulter will also have the advantage of a rapturous home support behind her at Queen's Club, while she has fond memories of facing Vekic, triumphing in their only previous meeting on the WTA Tour at the quarter-final stage of the 2024 San Diego Open - an event she went on to win.

Vekic is not the same player that reached the semi-finals of Wimbledon in 2024 and broke into the world's top 20.

The Croatian currently sits below Boulter in the world rankings and it is the Brit that is fancied to make it through to her first final at Queen's.

Alternative Bet: Total sets - 3 @ 11/10

Boulter may just about have the edge in this semi-final but this is unlikely to be a stroll in the park for the former world number 23, with the likelihood being this match goes to three sets.

Both players were pushed to a deciding set in their respective quarter-final successes against Rybakina and Pliskova, while Boulter, who earned a wildcard into the event, had to battle back from a set down in her first-round match against Leylah Fernandez.

With just four places separating these two players in the current world rankings, there is obviously not much between them and, with tiredness also expected to be a factor given their exploits on Friday, it is unlikely either player will be able to blow the other away in straight sets.

Katie Boulter v Donna Vekic Bet Builder Tip

• Over 22.5 games
• Over 5.5 breaks of serve
• Katie Boulter 8+ double faults
  
  Pays 5/1

With this match expected to go to three sets, it makes sense to assume that more than 22.5 games will be contested.

That threshold was passed in both players' quarter-finals contests, with Boulter's win over Rybakina featuring 30 games and Vekic's defeat of Pliskova requiring just one fewer at 29.

A high game total could also mean plenty of breaks of serve, with Boulter unlikely to be able to save as many break points as she did against Rybakina (12 of 14), while Vekic faced four break points against Pliskova, saving just one.

Complete the bet builder by backing Boulter to serve at least eight double faults, as despite her run to the semi-finals, she has produced 23 in the tournament, including nine each in her victories over Fernandez and Rybakina.
