O'Sullivan 5-1 He
Amazing end to that frame.
Watch. These. Pots. To be 5-0 down and knock these in, fair play.
Now will it be a one-off or can He Guoqiang get back into this match against the seven-time world champion?
This is a player who beat Jack Lisowski in the final round of qualifying to get here. 10-5 no less. If he's settled now, it will be interesting to see what happens.

That will give He Guoqiang a little bit of confidence. Eventually he has got his first frame on the board this afternoon. He waited a long time but it was worth waiting for.
O'Sullivan 5-1 He
He can!
Absolutely unreal long pots on yellow, green and brown earn the Chinese 25-year-old his first frame on the board.
The Crucible crowd responds with a rapturous reaction.
O'Sullivan 5-0 He
He Guoxiang wears a glove more associated with a pool player.
And he leaves a shot associated with a pool player on the last red - a reverse double into the middle pocket. And he gets it!
But there's no colour to follow - 18 points the lead so he puts the black safe and snookers Ronnie O'Sullivan on the yellow.
O'Sullivan 5-0 He
He Guoqiang just cannot string anything together though.
Two reds left and He has a 10-point lead but this frame is in the balance just like the previous one was.
O'Sullivan 5-0 He
Tell you what, He Guoqiang doesn't lack for bottle.
Takes on a very risky pink and nails it in the middle, then pumps in a mid-distance red.
O'Sullivan 5-0 He
Image source, PA MediaBut, as has happened throughout, it's Ronnie O'Sullivan who gets something going.
Well, he does until a 31 break ends with another really unexpected miss on a red.
O'Sullivan 5-0 He
Very, very scrappy start to frame six with both players throwing in some pretty poor misses.
O'Sullivan 5-0 He
We've been asking the question if all top 16 seeds will get through the first round (nine out of nine so far).
The experts/number crunchers on TV tell us the most seeds through was 15 seeds in 1983 when Jimmy White lost to Tony Meo and 1993 when Doug Mountjoy beat Alain Robidoux?
By the way, 1993 was the year of Ronnie O'Sullivan's Crucible debut.

It's horrible for He Guoqiang and it's starting to get the 'can't even win a frame'. You start to feel the match is lost and it's a case of 'can I get a frame on the board'.
The one thing Ronnie has always done well is the players are supposed to be beaten easily he beats easily. He always does it. Some players struggle through the first round but Ronnie dominates the players he's supposed to dominate.
O'Sullivan 5-0 He

He Guoqiang hit that [blue] too hard and has to face the consequences. You play the top players and they don't just want to beat you, they want to absolutely drill you.

O'Sullivan 5-0 He
O'Sullivan pounces - long blue dispatched as is a missable pink to the middle pocket.
That seals the frame. That will hurt He.
O'Sullivan 4-0 He

Don't forget to pot the blue! A chance missed for He Guoqiang.
O'Sullivan 4-0 He
Some shot from He after finishing very close to that brown.
He was penalised for a push shot in a previous frame.
This time, He knocks it in but then misses the blue!
O'Sullivan 4-0 He
That red on the cushion proves O'Sullivan's undoing.
The 'Rocket' jaws it. Great chance now for He Guoqiang to get on the board. Only the brown trickily placed - but he'll need it.
O'Sullivan 4-0 He
He Guoqiang takes a leaf out of the Rocket's book and switches hands to cut in a black.
He's very unlucky not to finish on a red - tries a delicate swerve to make the potting angle but misses it.
A 44-42 lead for the Chinese player but O'Sullivan is back in after a red to middle. One red on the side cushion the main obstacle...
O'Sullivan 4-0 He

You never really settle until you get your first frame on the board.
O'Sullivan 4-0 He
Here's how Ronnie O'Sullivan wrapped up that fourth frame before the interval.

If He Guoqiang can gets some points on the board it will help to settle him down a little.
