Boulter starts her clay-court swing on Tuesday when she plays Katerina Siniakova of the Czech Republic in the Madrid Open first round.

The Briton's experience on clay is still limited, having only played four top-level main-draw matches on the surface.

After winning one and losing one of her BJK Cup singles matches last week on indoor clay in the Netherlands, Boulter went to Alicante - where her fiancé Alex de Minaur has long been based - for a training week.

She decided that was the sensible option - instead of squeezing in another WTA clay-court event before Madrid - as she continues to manage a foot injury.

The issue has left her only able to play five tournaments this season, missing almost two months of the WTA Tour between the Australian Open in January and Indian Wells in March.

"I want to see the girls going higher and higher [in the rankings], but personally I have my own goals and try to focus on those a lot," added Boulter, who secured GB's place in the BJK Cup Finals alongside Jodie Burrage in the deciding doubles.

"For me I just need to try and stay healthy. That's that most important thing and then the ranking will take care of itself.

"Obviously I've dropped a little bit from last year but due to the fact I've not been able to play.

"It's not like my level has gone anywhere. I feel like my level is great so now it's about keeping myself healthy for the most important tournaments."
