What a beautiful lofted cover drive.
Lee dismissively lofts a cover drive for four - before drilling another boundary along the ground to bring up the hundred for her country in some style.

A fantastic effort. She had a long way to run in.
SA 95-1
And another one put down! Lizelle Lee lifts off-spinner Boochatham over the infield, long-off comes in and gets a hand to it buit can't hold on...
Lee 57, Luus 31
South Africa plunder four more singles - while Mel Farrell on TMS recalls her university days in Canberra. "I lived in a convent," is her surprising admission. "That's not very university-like," admits a shocked Alex Hartley.
Leg-spinner Laomi back, but she serves up a loose half-tracker outside off stump which Luus easily cuts for four. It's all smiles in the Proteas dugout.

I would rather see Lizelle Lee bat for 10 overs but play all her shots. But I know South Africa have asked her to try to bat through. The way she's playing, it's almost like she keeps remembering to try and bat through.

Lizelle Lee is either playing a forward defence or going full hammer and tongs. No in-between.
Lee 55, Luus 25
A rare Lizelle Lee forward defence is spotted, while she drills the last ball of the over straight to captain Tippoch in the covers.
The score predictor has SA on course for 175. Basically, they've just doubled the score and added five for good measure.
When you love to sweep, you're in glad company - Sune Luus in particular likes a sweep shot, helping herself to a couple of twos and a single from Kamchomphu's off-spin. Sweep, sweep, sweep.
Thanks, Amy. South Africa moving up through the gears nicely, Thailand really ought to stop bowling full tosses - while they may sorely regret dropping Lizelle Lee just now, while she's in this sort of form.
Right, that's me done for a bit.
Here's Mark Mitchener.
A dot ends a chastening over from Chanida Sutthiruang.

A savage blow to reach the half-century.
Well, what a way to bring up a half-century - a thunderous six down the ground!
That was huge. Lee's 50 has come from 35 balls, with nine fours and two sixes. Brutal.
Whoops. That'll be another full toss and it's easy for Lizelle Lee to work it away to the boundary rope.
She's one away from a half-century.

I don't know what she was thinking running there.

Luus got very lucky there.
SA 70-1
The free hit doesn't clear the fielder at mid-off - oh, and Luus is almost run out as she comes through to the non striker's end!
That was... close.
