The overcast conditions in London promised to help South Africa's quicks

The overcast conditions in London promised to help South Africa's quicks, with reigning champions Australia also boasting an impressive pace attack.

Overcast conditions in London promised to help South Africa's quicks as they battled reigning champions Australia in the World Test Championship final at Lord's on Wednesday.

Both captains won their respective tosses and elected to bowl first.

The hosts' decision will come as no surprise given the threat posed by Australia's pace attack, and the fact that the visitors' batters struggled in the recent series at home against England's quicks.

Australia's Marnus Labuschagne will be thrust straight into the action after being promoted to open for the first time in his Test career.

"We'll have a bowl first," said Bavuma at the toss. "The surface looks a good one, with solid overhead conditions.

"I'm happy. It's too late now for anything else. We've selected the best team for the conditions."

"It's (a) massive (occasion). I think all of us have some sort of allegiance to Lord's. Should be a spectacle of a game."

Australia captain Pat Cummins said his side were happy to bat first.

"There's a few clouds but that's not unusual for England. It's dry and might turn later in the match.

"I don't think there's any extra pressure (as defending champions). We've been here before and won it. This week is about enjoying it."
