West Indies defeated India by four wickets while South Africa and England also notched victories at the ICC U19 Cricket World Cup on Sunday.
After winning the toss and electing to bowl, the West Indies made a bright start to their encounter at Tony Ireland Stadium in Townsville.
Opening bowlers Ronsford Beaton (3-33 off 10 overs) and Jerome Jones (2-23 off 10) caused plenty of problems for the top order and India were reeling at 50 for four in the 20th over when highly rated skipper Unmukt Chand fell for 22.
Smit Patel (51) and Vijay Zol (26) tried to resurrect things but India always struggled to score quickly against a miserly West Indian bowling attack that also included the impressive Kyle Mayers (2-35 off 10).
They were restricted to 166-8 but history repeated itself as the West Indies struggled in the early stages.
Sandeep Sharma (2-27 off 10) was swinging the ball prodigiously, causing a series of problems for the batsmen, with West Indies openers Kraigg Brathwaite and Sunil Ambris both dismissed for four.
John Campbell and Anthony Alleyne halted the flow of wickets with a slow but steady 58-run partnership and despite the efforts of Indian spinner Harmeet Singh (3-35 off 10), the winners were relatively comfortable after their early scare.
Kyle Mayers (43) impressed with four fours and one six in his 54-ball knock as the West Indies reached the victory target with four wickets in hand and 17 balls to spare.
South Africa opener Quinton de Kock (95) was the star for his side as they posted a 133-run win over Bangladesh in Brisbane.
De Kock's 93-ball innings – which included nine fours and two sixes – gave South Africa the platform to post a score of 294-8, helped by the efforts of Theunis de Bruyn (63).
In response, only four Bangladesh batsmen reached double figures with Anamul Haque (39) and Al-Amin (33) struggling for support as they were dismissed for just 161 in response.
England bounced back from a first-day defeat to Australia with a seven-wicket win over Ireland in Townsville.
Ireland were skittled for just 109 with left-armer Reece Topley (3-14 off nine) the chief destroyer.
Ben Foakes (32), Aneesh Kapil (31 not out) and Craig Overton (26 not out) led England to victory as they won with 82 balls to spare.
In Sunday's other match, New Zealand beat Scotland by 39 runs on the Sunshine Coast.
Will Young (115) and Robert O'Donnell (50) helped the winners post a total of 247-9 from their 50 overs, with Scotland bowled out for 208 in response.
Connor Neynens (3-24 off 10) and Ish Sodhi (3-35 off 10) starred with the ball for the Kiwis.
