Late entrant Kiki Bertens stunned world No 1 Ashleigh Barty with a comeback three-set win at the WTA Finals in Shenzhen Tuesday.
All four players can still qualify from Red Group after Belinda Bencic's three-set victory over Petra Kvitova later in the day.
Bertens looked in trouble at a set and break down, but turned things around with ruthless returning and aggressive play at the net to overwhelm Barty, who could have sealed a spot in the semi-finals with a win. The world No.10 won 3-6, 6-3, 6-4 in two hours and nine minutes in a see-saw match featuring 12 breaks of serve.
"Of course you're always ready to play, but I did not see it coming today," Bertens said of her late call-up. "In the beginning I was struggling. As the match continued, I felt better and better."
