Norm Duke had three consecutive 300s in a standard PBA Tour event in 1996, the PBA said Monday, but the performance didn't count as a 900 series because he ended one round with two perfect games and started the next round with the third.
Azarenka on the other hand, is 8-0, as her withdrawal from a tuneup event in Brisbane due to a pedicure-induced big toe injury, doesn't count as a loss.
