Ryan Day created a wonderful chance for himself - it's important to start off well against Ronnie because he's such a good front-runner.
You cannot afford to miss easy shots like the red Ryan missed because Ronnie's cue ball control is impeccable and he made that century look easy.
O'Sullivan 1-0 Day
It takes Ronnie O'Sullivan about seven minutes to punish that Ryan Day miss with a fantastic, flawless 123 clearance.

Seven-time world champion on BBC Two
Even someone who's had the success here that Ronnie has, it's nice to get an easy opportunity in the opening frame, to get your cue arm going.
And that's exactly what he's been gifted by his opponent.
This first session of four frames, Ryan Day has to get one of them - to be involved in this match. If he loses this mini-session 4-0, he's in big trouble.
Murphy 6-10 Maguire
Hard to believe it's almost 20 years since Shaun Murphy won the World Championship with a fantastic fightback to beat Matthew Stevens.
It remains his only Crucible crown despite reaching three finals since - losing to John Higgins in 2009, Stuart Bingham in 2015 and Mark Selby in 2021.
Making a fifth final this year though will be a tall order - his opponent and long-time rival Stephen Maguire needs just three frames this morning to make the Magician disappear from the 2024 edition.

Positive start from Ryan Day, who knocks in a long red off Ronnie O'Sullivan's break-off shot.
However, 16 points later, he misses a very routine red - he's left the 'Rocket' in with the reds split wide open.

Not bad numbers, eh?
He wants that seven to tick over to an eight though, absolutely no doubt.

Ronnie brings so much to the tournament, so much to the Crucible.
So much excitement, so much electricity and he's a great entertainer.
He's had a wonderful year, he looks in great form and he looks like he's really focused.

Seven-time champion Ronnie O'Sullivan believes he is capable of winning a world title in his 50s after he thrashed Jackson Page 10-1 to reach the last 16 at the 2024 event.
O'Sullivan, 48, is already the oldest snooker world champion after winning in 2022, aged 46, and would need to lift the trophy again in 2026 or later to become the first winner aged 50 or over.
"I know the ability is there it's just finding the right formula," O'Sullivan told BBC Two. "I've already broken the rules for snooker, I'm still going at 48, 49 and I'm seeing what's possible now.
"Can I win a World Championship at 50, who knows? I'm probably the only player able to do that but let's see, let's have an experiment."
