RONNIE O'SULLIVAN'S nemesis reached "God mode" ahead of the pair's clash at the Saudi Arabia Masters.
The Rocket progressed to the second round after beating Lei Peifan 5-1.
But the story of the day was Zhang Anda, who thrashed Ben Woollaston in devastating fashion.
The Chinese star won 5-0 and scored a century in four of those frames, scoring a massive 138 three times as Woollaston managed just 15 points.
Fans were blown away by the performance, which set-up a meeting with O'Sullivan in round two.
One fan said: "Always hear Zhang Anda described as solid, but this is just outrageous scoring."

Another added: "Sometimes you just come across a player in 'God' mode. Anda played flawless snooker."
A third wrote: "Zhang Anda's performance tonight was unbelievable."
And another commented: "Zhang Anda what have you just done 😅😅 Three 138 breaks is insane 😂
Round two could prove to be a tasty affair with Zhang in fine form, while O'Sullivan has not won a tournament since March after losing in the Shanghai Masters for the first time in eight years in July.
