Devon Conway struck a composed half-century before a clinical bowling display powered New Zealand to a dominant 68-run win over South Africa in the second T20I at Seddon Park, Hamilton, on Tuesday, levelling the five-match series 1-1.After being sent in to bat, New Zealand posted a competitive 175/6, anchored by Conway’s 60 off 49 balls. The left-hander, who had a quiet T20 World Cup campaign, made the most of his opportunity with a controlled knock featuring five fours and two sixes. “It’s been a very quiet couple of months… it’s nice to come back and contribute,” Conway said after the match.Scorecard: New Zealand vs South Africa, 2nd T20INew Zealand got off to a brisk start, reaching 43 without loss in the powerplay, with Conway and Tom Latham setting the tone. However, the hosts found it difficult to accelerate in the middle overs as the pitch slowed down and became two-paced. Contributions from Nick Kelly (21) and Mitchell Santner (20) kept the scoreboard ticking, before a late flourish from Josh Clarkson, who smashed 26 off just nine balls, lifted the total.South Africa struggle in chaseIn response, South Africa never got going and were bowled out for just 107 in 15.3 overs. The chase unraveled early at 31/3, and despite a brief counter from George Linde, who top-scored with a quickfire 33, the visitors collapsed under sustained pressure.Pace duo Ben Sears (3/14) and Lockie Ferguson (3/16) were outstanding, exploiting the variable bounce and pace on offer. All 10 South African wickets fell to catches, underlining the effectiveness of New Zealand’s disciplined bowling.South Africa captain Keshav Maharaj admitted his side misread the conditions. “We thought the dew would play a factor, but the wicket got worse. New Zealand bowled really well and stifled us early,” he said.The result comes after South Africa’s seven-wicket win in the series opener and keeps the contest finely poised. With both sides fielding relatively inexperienced squads following the T20 World Cup, the series has offered opportunities for emerging players to step up.The third T20I will be played in Auckland on Friday.
