The top eight qualifiers at the end of the season will be invited to the finale in Guangzhou in December.
Christie, who beat Indonesian compatriot Anthony Sinisuka Ginting in the CROWN GROUP Australian Open 2019 final, trails top-ranked Viktor Axelsen by 7,400 points midway through the season. Axelsen has had a good year so far, having won the Spain Masters and the India Open as well as finishing runner-up at the All England, and being a semifinalist at three other events.
Ginting – runner-up in Singapore and Australia – is at No.5, followed by Kidambi Srikanth, who was quarterfinalist in five of his six tournaments.
The biggest mover in Australia was Wang Tzu Wei, whose semifinal finish saw him jump five places to No.8, just ahead of HSBC BWF World Tour Finals champion Shi Yu Qi, who has played only five World Tour events so far. Shi won the Swiss Open and was semifinalist at the All England and the Malaysia Open.
In tenth place is Malaysia’s Lee Zii Jia, who has gained from being in five quarterfinals out of nine tournaments.
Prominent names who aren’t yet in the top ten are Anders Antonsen (No.15) – winner of the Indonesia Masters; Chou Tien Chen (No.22), who has yet to win a tournament this year, and Sameer Verma (No.30).
