South Africa bowler Dale Steyn felt back to his best on comeback from injury, after ending day one of the first Test against England with three wickets to his name.
Steyn missed almost all of the Proteas tour of India with a groin injury, but returned in fine form in Durban, having England captain Alastair Cook caught in the slips in just his second over back in action.
Debutant Alex Hales also fell to Steyn as England stumbled to 12-2, but Nick Compton (63 not out) and James Taylor (70) put on 125 for the fourth wicket, before the top-ranked Test bowler in the world struck yet again to end the day with figures of 3-29.
Steyn said: "It's been frustrating sitting on the sidelines for the last six weeks but I've worked hard with a trainer, lost a few kilograms and it's been nice to get back on the field today and contribute.
"Hash [South Africa captain, Hashim Amla] is always asking the leader of the attack to set the tone and when we won the toss and bowled I felt I did my job today.
"It was great to get the first wicket, especially the English captain. It sets the tone for the team.
"Everything felt good. I'm not too bothered whether it's coming out at 150, 135 or 130 [kilometres per hour].
"I always want to bowl fast. If I'm causing trouble for the batter at the other end then I feel I'm hitting my straps."
Steyn suggested Compton and Taylor's recovery may have been helped by South Africa's struggles to manage the ball on a wet day as England ground their way to 179-4 at stumps.
"When you are coming on and off for rain, it's tough," he added. "This field holds the water a little bit, the ball is kind of damp all day and it made it tough to get it to swing and shape.
"But hopefully tomorrow the sun comes out and it's nice and warm, then it will be better. We were just starting to reverse the ball towards the end of the day."
