'Bazball' was put on the backburner as South Africa's seamers made inroads into England's top-order to leave the hosts 5-100 at lunch on the opening day of the first Test at Lord's.

England's hopes to resurrect the innings rest largely with Ollie Pope, who is unbeaten on 51 and will resume the afternoon session on Wednesday with Ben Foakes.

England lost captain Ben Stokes with the final delivery before the interval, after South Africa won the toss.

Stokes had looked to attack the bowling and reached 20 from 30 balls before he was caught by third slip Keegan Petersen off seamer Anrich Nortje (2-37).

South Africa opted to bowl under overcast skies, with Stokes conceding at the toss he would have done the same.

It was perfect conditions for the tourists' venomous four-prong pace attack on a wicket that looks a little 'two-paced', with deliveries rising off a surprising length and making it difficult for the batsmen to feel confident of their strokeplay.

Kagiso Rabada (2-26), who was an injury doubt going into the game, made an excellent start, dismissing both England openers cheaply to catches behind the wicket.

Alex Lees (5) went too hard at a delivery just outside his off-stump and was caught comfortably by wicketkeeper Kyle Verreynne, while Zak Crawley (9) edged Radaba to a diving Aiden Markram at second slip.

Crawley now has single figures in eight of his last 11 Test innings, with former England batsman Mark Butcher suggesting in his Sky Sports coverage the selectors were "cruel" to keep playing him.

Joe Root (8) scored a superb unbeaten century at Lord's earlier this summer but could not replicate that as he was trapped leg before wicket by left-arm seamer Marco Jansen, the in-swinging ball shown to be clipping leg stump.

Jonny Bairstow has also had a golden summer but he produced a shot to forget when he missed a straight delivery from Nortje and was bowled for a duck.

The match is the first of three Tests in the series, with matches to be played at Old Trafford (August 25-29) and The Oval (September 8-12).
