It's a 1:08.414 for Muroya and we will have to wait to see what Sonka can do
Sonka is cleared into the track and it's a 178.39kts entry speed, so he's all good
The first split is over a second faster... and it's an easy green!
This is great flying, green again and no issues – he's got his eye on the win here in Porto and this is a great start!
1:07.991 for Sonka and he is in the Porto Final 4 with ease!
Bad news for Muroya, who will fall behind Sonka in the overall standings with just two races to go after this weekend
Next head to head is the second of the Czech pilots
Petr Kopfstein flies against the current standings leader, Kirby Chambliss
178.44kts and Kopfstein is in the track
This is very steady and disciplined flying...
His time will be the marker for Chambliss and this is a clean and pretty perfect performance
It's a 1:08.452 for Chambliss to beat – this could go either way
Realistically Chambliss will have to pick up a penalty for Kopfstein to progress and he's been on good form already today so we're not expecting that
Will Chambliss make it three in a row today?
179.53kts for Chambliss into the track
And he's green from the off... this is the calibre of a former World Champion
And he's green all the way and secures his place in the Final 4 – taking him closer to that third win!
It's a 1:07.835 for Chambliss and he's through!
Two remaining head to heads – McLeod V Dolderer and Brageot V Hall
