Siegemund has won all 3 of their previous matches. Their last one was in May this year. She won on clay in straight sets. All their matches were on clay.
Siegemund is inexperienced on grass and Brengle has a poor record on the surface. Siegemund has only played 7 matches and all her wins were in qualifying rounds. She won 4 of the 7. Brengle won 19 of her 39 matches on grass. She has won just 3 of her last 10 on the surface.
I would give a slight edge to Siegemund but this one could go either way. I think we see a bigger price on her.
Back Siegemund if she gets broken first.
