Jannik Sinner to win at least a set v Stan Wawrinka
1pt 4-7 Betfred

Preview

The seeds have been falling like skittles in the European Open in Antwerp this week and it's just possible the surprises could continue in the semi-finals.

Stan Wawrinka is playing pretty well but even the super Swiss may not be totally safe against promising young Italian Jannik Sinner, who was a 100-1 chance for the title earlier in the week.

It's a huge match for anyone on Sinner each-way but given the record of big names capitulating in Belgium in recent days, there is hope for anyone on the outsider at big prices.

Sinner, who has already ousted Kamil Majchrzak, top seed Gael Monfils and Frances Tiafoe this week, could have the legs to outrun Wawrinka. But a safer way of punting could be to back him to win at least a set.

In Stockholm Filip Krajinovic will meet Pablo Carreno Busta for a place in the final, while in the women's singles in Moscow Belinda Bencic could take a lot of stopping in her semi-final rumble with Kristina Mladenovic.
