Simon Harmer titled the first Test between South Africa and Bangladesh in the Proteas' favour on day two in Durban.
South Africa ended day one on 233-4 with Temba Bavuma on 53.
Bavuma added 40 to his overnight score, falling seven runs shy of a century, but Harmer led South Africa's lower-order resistance with an unbeaten 38.
After the hosts were bowled out for 367, Harmer - returning after over six years away from the longest format - did significant damage with the ball, claiming all four wickets, including the scalp of captain Mominul Haque for a duck as the tourists reached stumps on 98-4.
Khaled Ahmed got Bangladesh into the lower order by removing Kyle Verreynne and Wiaan Mulder with successive deliveries, only for the tourists to then be frustrated by a partnership of 53 between Bavuma and Keshav Maharaj (19).
That stand was broken when Bavuma was undone by some sharp turn from Mehidy Hasan, who struck leg stump before Ebadot Hossain snuck the next delivery through the gap to dislodge Maharaj.
Harmer counter-attacked in style, hitting four fours and a six, and then continued to torment Bangladesh with ball in hand.
Shadman Islam went for nine as Harmer got one to keep low and clatter into middle stump and then exploited the turn to bowl Najmul Hossain Shanto for 38 with a ball that beat the outside edge.
Keegan Petersen's one-handed diving catch gave Harmer his third and the crucial wicket of Mominul and he then had Mushifqur Rahim caught behind for seven. Mahmudul Hasan Joy represents Bangladesh's best hope of a fightback, having reached stumps unbeaten on 44.
Harmer makes belated Test impact
Making his first Test appearance since 2015, Harmer, who curtailed his international career to sign a Kolpak deal with Essex in 2017, produced an high-quality demonstration of his quality. Thirty-eight represented a highest score with the bat in this his sixth Test, while he is on course to easily surpass his previous best innings figures of 4-61.
Harmer had claimed 4-42 at the close of play, bowling seven maidens in his 20 overs.
More misery for Mominul
Mominul's exit, though the product of a superb piece of fielding, meant he went for a duck in a second successive Test, having done so in the first innings against New Zealand in Christchurch in January.
The Bangladesh skipper has now produced a single-figure score in six of his nine innings in the longest format.
ECB chief insists no decision made on Mott future
England and Wales Cricket Board chief executive Richard Gould has denied reports a decision has already been made on Matthew Mott's future as white-ball coach.
Mott's future has been called into question in the aftermath of England's failure to defend their T20 World Cup crown in the United States and West Indies, losing to India in the semi-finals.
Mott also oversaw England's calamitous 50-over World Cup campaign last year, as they lost six of their nine matches in India and crashed out in the group stage.
Reports earlier this week suggested the decision had already been made to dispense with Mott's services, with Eoin Morgan a contender to succeed him, though the former limited-overs captain has since said he has no interest in the role.
Asked by BBC Test Match Special if Mott's future had already been decided, Gould said: "That's not true. That's certainly not true.
"Matthew Mott is a really good guy and coach. He's got a great track record and it is the same with [captain] Jos [Buttler].
"We are always assessing options - that is what happens in high-performance sport, you are always assessing your options.
"You never want to be drawn into being given the dreaded vote of confidence or anything like that. Competitive sport always brings scrutiny and decisions.
"We'll constantly want to assess our options but we'll always want to do the right thing by the sport, the team and individuals."
West Indies grab three late wickets on day one as third Test against England in the balance
England lost three wickets in a dramatic end to day one of the third Test against West Indies, leaving them in a precarious position after restricting the tourists for 282.
Gus Atkinson finished with figures of 4-67, while Chris Woakes took 3-69 for England, as only a fine sixth-wicket stand from Jason Holder and Joshua Da Silva saved West Indies from being bowled out for a much lower total.
But England, chasing a 3-0 series whitewash, let their dominant position slip when taking up the bat for the final 35 minutes, Zak Crawley (18), Ben Duckett (3) and Mark Wood (0) being dispatched as bowler Jayden Seales dropped them to 38-3.
Windies skipper Kraigg Brathwaite won the toss and chose to bat, leading his side to a solid start before a spell of three wickets in five overs before lunch put England on top.
Atkinson accounted for Mikyle Louis (26) and Alick Athanaze (2) on either side of Wood sending stumps flying with a full delivery to dismiss Kirk McKenize for 12.
Brathwaite's knock of 61 was brought to a halt shortly after the action resumed, the captain gloving Wood's leg-side ball to Jamie Smith as the tourists slid from 76-0 to 115-5 in 45 balls.
Holder (59) and Da Silva (49) then shared 108 to drag the Windies towards a respectable total, but things looked bleak for them when the latter feathered Woakes' ball through to Smith.
Having gone 30 overs without a wicket, England needed just 14 more to polish off the tail, the highlight being a terrific diving catch from Joe Root to send Gudakesh Motie (8) packing.
England were given just over half an hour with the bat to cap Friday's action, but any hopes of a serene finish were soon dashed.
Holder made two terrific catches off Seales' bowling, the first from Crawley's thick outside edge and the second to dismiss Wood for a duck, either side of Alzarri Joseph's cracking delivery accounting for Duckett.
That spell ensured what had been a good day for the hosts ended on a sour note, with the Windies sure to target quick wickets when the action resumes on Saturday.
Data Debrief: Atkinson and Seales dominate
This series began with all the focus on James Anderson as England's greatest-ever bowler bowed out at Lord's, but Atkinson has taken centre-stage since making his Test debut in the opening match and now has 20 wickets through five innings.
That is eight more than West Indies' Jayden Seales, the next-most prolific bowler in this series, has managed.
Seales was determined to have an impact on day one, though, and his two wickets at the death have set the stage for a far more competitive match than those England won at Lord's and Trent Bridge.
Bairstow set sights on swift England Test return
Jonny Bairstow bit back when asked if he was targeting an England return, insisting it is "all I want to do."
Bairstow was dropped from England's Test team for the ongoing series against West Indies.
The 34-year-old was part of England's T20 World Cup squad, and played in all five Tests of the tour of India earlier this year.
Bairstow has made 100 Test appearances, and when asked what his immediate target was, the wicketkeeper-batsman told former England captain and now-BBC Sport pundit Michael Vaughan: "All I want to do is play for England. That's end of.
"You don't need to ask me that do you? I think you know me well enough and I think you've known me for long enough to know that."
Bairstow did, however, enjoy a break away from the game, having had four weeks off before he joined the Welsh Fire for the Hundred.
He said: "At the same time it's been a great period of time.
"I had the best part of seven months away from home. Since January, I had five nights at home in my own bed since, until three weeks ago.
"That's the thing you have to sacrifice, time at home but at the same time, when you are away for that period of time, it takes its toll."
England are 2-0 up against the Windies in their three-match series, with the final Test starting at Edgbaston on Friday.
