Another two champions were crowned at WTA International-level events last week, which has led to movement in the top 20 in a crowded Porsche Race to Singapore as the month of July comes to an end. 

The biggest mover in the top 20 for the week is China's Peng Shuai, who moves up five spots to No.18 on the back of her second career WTA title in Nanchang at the Jiangxi Open.

Peng has never qualified for the BNP Paribas WTA Finals presented by SC Global in singles, but won the doubles event in 2013 and again reached the final in 2014. 

After reaching the semifinals at the Ericsson Open in Bastad, falling to eventual champion Katerina Siniakova, France's Caroline Garcia moves up three places to No.13 on the singles leaderboard, while Kiki Bertens, who was also in action in Bastad, moves up the same amount to No.17. 

Ericsson Open champion Siniakova, who claimed her second title of the season after winning the Shenzhen Open in January, zoomed up 16 spots to No.39, while the other losing semifinalist in Bastad, breakout Belgian Elise Mertens, moved up nine places to No.34. 

The top 10 remained unchanged in personnel, but Caroline Wozniacki swapped places with Roland Garros champion Jelena Ostapenko to No.7 in the race after reaching her fifth final of 2017 in Bastad. 

Here's how the Porsche Race to Singapore Leaderboard in singles stands as of July 31.
