These are the two wickets to fall so far. Oval Invincibles will be hoping for two more though, as Lee and Sciver-Brunt are looking in good touch.
Lizelle Lee is not just about power, she also shows great technnique to open the face and guide the ball down to third for four.
Rockets reach 71-2 at the halfway stage, with 85 runs needed.
They are well and truly in this contest.
Lizelle Lee is at it again.
She smashes a length ball from Nadine de Klerk through the leg side for her second six of the innings.
Nat Sciver-Brunt survives. The ball was going on to miss leg stump.
Not the best review by Invincibles, but shows how much they value Sciver-Brunt's wicket.
Marizanne Kapp is convinced she has Nat Sciver-Brunt lbw after the ball clatters into her back leg.
The umpire says no but Kapp persuades her skipper to send it upstairs.
Brilliant shot from Lizelle Lee as she nails the ball almost nonchalantly over deep mid-wicket for a huge six!
She made that look effortless.
111 runs needed

A lot rests on Sciver-Brunt and Lizelle Lee you feel.
Harmanpreet lbw b Gray 9 (Rockets 42-2)
Harmanpreet Kaur goes!
It is a full, straight delivery from Eva Gray and Harmanpreet goes for a rather ugly hoick across the line, with the ball missing the bat and smacking into her back leg.
She has a brief chat with Lizzelle Lee about a review, but wisely decides against it.
114 runs needed
Five runs from the latest set by Ryana MacDonald-Gay, but it could have been more as Lizelle Lee failed to take full advantage of a couple of juicy half-volleys on leg stump.
Lee looks visibility frustrated after she could only run through for a single.
120 runs needed
Time for a bit of spin as Sophia Smale comes into the attack.
We saw how this pitch took some turn earlier but Smale is a bit too full in her opening set, allowing Lizelle Lee the chance to negate any spin and smash back-to-back boundaries.
130 runs needed
Harmanpreet Kaur is the new batter. She gives herself a couple of sighters before dispatching a ball from Nadine de Klerk over deep mid-wicket for four.
Lovely shot.
Smith c Bates b Kapp 9 (Rockets 19-1)
Breakthrough!
That attacking intent brings risk and it has done for Bryony Smith, who skips down the track but can only launch the ball straight to Suzie Bates at mid-off.
Bryony Smith also looks in good touch early on, pulling Nadine de Klerk through the leg side for another boundary.
This has been a positive start by Rockets.
Fortune for Lizelle Lee as she attempts to hit her first delivery into the leg side, but it hits a leading edge and flies in the air down to deep third for four.
No luck needed there, though, Kapp offers Lee some width and she clatters the ball through point to the rope.
Lizelle Lee and Bryony Smith are powerful hitters up top for Trent Rockets. They will have little time to get their eye in.
Marizanne Kapp will open the bowling for Invincibles.
Thanks, Ffion.
What a comeback that was from Invincibles, who looked on the ropes midway through their innings on a surface that was turning sharply.
Instead, mainly thanks to the big hitting of Nadine de Klerk, 155 looks an imposing score.
The pressure will be on the Trent Rockets batters from the off.
Can the defending champions finish their campaign with a win in front of their home fans, or can Trent Rockets produce some brilliance to chase this target down?
To take you through the second half of this game is Tom Mallows.
Nadine de Klerk, speaking to Sky Sports: "We are more than happy with that score. There was a bit of turn in the pitch for the spinners but I think good cricket shots have good value on a ground like this. The outfield is really good as well so hopefully we can give it a good crack and defend the score.
"Once I got to the middle I just tried to get myself in. It was a bit harder to take on the spinners on because of the turn so I always knew when the seamers came back on I would try and take them on. Luckily it came off today."
It was a tough finish for the Rockets' bowlers, who started brilliantly by reducing Invincibles to 85-5 and it looked really tough for batting.
Alexa Stonehouse took two early wickets but was hit for 27 from her last five balls.
Mady Villiers is dropped in the outfield by Fran Wilson, which allows the pair to run two from the final ball.
That completes an astonishing fightback from Oval Invincibles, largely thanks to Nadine de Klerk's unbeaten 51 from 25 balls.
Trent Rockets need 156 to win.
