Just four singles come off that set from Johnson, whose bowling figures are now 15 runs conceded off as many deliveries.
Will Jacks is coming in for another five, having only gone for three with his first set.
Phoenix 74-3
Smith currently sits on 33 runs off just 18 balls with the bat, bringing up almost half of Phoenix's runs so far.
After several consecutive sets of spin, left-arm pace bowler Spencer Johnson is recalled to the attack.
Phoenix 73-3
Another six!
Smith is motoring here, smacking Sowter over the rope in a shout almost identical to how he dispatched Narine in the previous set.
Phoenix 67-3
Jamie Smith is getting in the groove here, a great drive through the covers for four. Smith is targeting Sowter.
Phoenix 62-3
That's more like it!
A brilliant shot from Jamie Smith, who takes on Narine again and smashes the ball straight over his head. To make it even better, it is met by a great catch in the crowd.
10 runs off the final two balls of Narine's set accelerates the Phoenix's score at the halfway stage.
Phoenix 52-3
A wait for a boundary from the Phoenix finally ends as Jamie Smith hits Narine straight down the ground for four.
Phoenix 50-3
Another set that only goes for three runs. More economical bowling from Jacks, with both Smith and Moeen struggling to really get going with the bat.
The 50 is up for the Phoenix, but they would have wanted that to come much sooner.
Phoenix 47-3
Just three runs off the latest set, two of which coming from Moeen Ali who came into the crease after Livingstone was removed. Good bowling there from Narine.
More spin up next, this time it is Will Jacks.
WICKET
Livingstone 3 c Klaasen b Sowter (Phoenix 44-3)
What a catch!
Klaasen out on the boundary with a great catch as Liam Livingstone goes cheaply for three.
Nathan Sowter is now 2-4 off his 10 balls. A great start for the Invincibles.
Phoenix 42-2
Jamie Smith gets his first boundary with a good cut shot off Narine for four, whose first set is a largely tidy one.
Spin proving to be very economical for Phoenix so far.
Phoenix 36-2
A brilliant first set from Sowter, who goes for just two runs and takes the big wicket of Ben Duckett.
That is the end of the powerplay and the Phoenix find themselves without both of their opening batters and Sunil Narine next to bowl.
WICKET
Duckett c Cox b Sowter 23 (Phoenix 35-2)
The gamble on Sowter worked. Just two balls into his first set and Duckett, looking to smash the ball, skies the delivery and it's a solid catch from Cox to remove Duckett on 23.
Liam Livingstone is next in.
Post update
Nathan Sowter comes into the attack...
How's stat?!
According to CricViz's captaincy grid Sam Curran is a good option to his England white-ball team-mate Ben Duckett.
Leg-spinner Nathan Sowter is a bad option to bowl at Duckett.
The problems of being a captain.
Phoenix 34-1
After starting his second set with three singles, Johnson is pulled for four by Duckett, who looks in real control early on inside this innings. A dot ball from Johnson follows Duckett's boundary.
WICKET
Smeed c Sowter b Chappell 6 (Phoenix 27-1)
Instant reply from Chappell who gets the breakthrough. Smeed did not get a hold of that ball and chips one up to Sowter who is gifted an easy catch.
Jamie Smith is next in to bat.
Phoenix 27-0
Will Smeed gets in on the boundary action, driving Chappell through the covers for four. Chappell has given away three boundaries from four deliveries so far.
Phoenix 22-0
Back-to-back fours for Duckett, a very clever tickle down the off side for his latest boundary. Duckett is already 17 off nine here.
Phoenix 18-0
In the same way that Duckett disposed of Curran's first ball, Duckett cracks Chappell's first delivery for a four.
Phoenix 14-0
Just one more from the final two balls for Phoenix as Curran goes for nine off his first set.
