Katie Boulter – Solana Sierra 02-07-2025

This year's Wimbledon on the men's side has delivered surprising results so far. Few would have thought that Zverev, Medvedev, Musetti, Rune and Bublik would be eliminated in the 1st round. But they did. Fortunately, none of these were on our odds list, but our tips have also been a victim of the fact that even the tennis ball is round.

But on the women's side, things have gone more as expected. And then it will also be easier to hit the odds. We have 6 out of 7 bets in, and we are stepping up the pace with four new bets today. No guarantees, but it would be wrong not to continue when things have gone so well, so far.

Katie Boulter – Solana Sierra

Today's main match from us will be the match between the home hope Boulter, against the inexperienced Sierra. Since Raducanu could soon be finished with this year's tournament by the end of the day, Boulter could easily be the one the British must rely on. And at Wimbledon, the audience knows how to cheer on their own.

Katie Boulter

2025 has not been a particularly good year for Boulter. One title, and 16-10 overall, has meant that she is no longer Britain's best tennis player. That is now Emma Raducanu. But there is something about Brits and grass. Especially on home turf. It's like these are the conditions they are bred for. Circus horses that can smell sawdust. And what Boulter showed in the first round was certainly worth seeing.

Because she doesn't really have very impressive statistics against the top 10 in the world. That has been her Achilles heel. 16 of 19 matches have been lost, which is why the victory against Badosa was so impressive. Because when it clicks, Boulter has a game that can challenge the best. She was as high as No. 23 in the world last year, and her serve-and-forehand combination is perfect for these conditions. And the quarter-finals in Nottingham (grass) last week prove it. A tournament she won in both 2023 and 2024.

But then there was this thing about stability. Because she is often down to 55-57% on her 1st serve, and she often plays with a small margin from the baseline. And in many ways she is reminiscent of Ostapenko, Kvitova and Sabalenka. And that is exactly why it was so nice to see that she served 68% of her 1st serves against Badosa. On the other hand, we do not think we should emphasize her 23 unforced errors too much. Against Badosa she got far more balls back than she will here, and it is natural that the number of errors was higher against a player of such high quality. In addition, the match went over three long sets. Against Sierra, who is also an aggressive player, the exchanges will be shorter.

Solana Sierra

Sierra is only 21 years old, but she has already become the best female tennis player in Argentina. And unlike most South Americans, she plays an aggressive style of tennis, rather than the more patient type that suits the red clay. So basically she should be in her element here.

But she was actually supposed to be on the plane to the next tournament. Possibly sightseeing in London. Because Sierra lost the last qualifying round for this year's Wimbledon, but was still allowed to join due to an injury to another player. She thanked, bowed and just as well won the 1st round against Gadecki. And thus she set a new personal record in a Grand Slam context, as she has never won a 1st round before.

Sierra has nothing to show for it at WTA level. She has won a bunch of clay tournaments at Challenger and ITF level, but on the biggest stage she is terribly inexperienced. And against Boulter, on her home court, on the next biggest court in Wimbledon, she could quickly get serious. But her aggression from the baseline, and the way she attacks the net, could knock Boulter off the stick if the Briton is not at work. But if there are two weeks a year that British tennis players work overtime, it is these two weeks.

God save the Queen

Of course, you should be careful of players who have been given the gift of life. In a figurative sense. Because Sierra should have been out, and tennis history is full of these people who come in as lucky losers with nothing to lose, and make it far into the tournament. But we think Boulter was triggered by no longer being the highest ranked player in Britain, and that the home crowd will send her on safely. She has the experience on grass, and the experience from the big stage, and Sierra will probably be affected by the seriousness. And if Boulter manages to avoid too many double faults (7 in the 1st round) and keep the errors to a minimum, then the following bets should be in place;
