Australia Under-19s needed just 32.1 overs to chase down Zimbabwe Under-19s' 184, as a century from Jaron Morgan helped them secure an eight-wicket win in Visakhapatnam - their second victory in the Quadrangular Under-19 Series.

Morgan smashed 11 fours and five sixes during his 92-ball 110, and added 107 for the second wicket with Damien Mortimer, who chipped in with 41, to see Australia through.

Zimbabwe, electing to bat, had got off to a shaky start and were unable to negotiate the pace of Matthew Fotia and Guy Walker, who toppled the top order and left them struggling at 61 for 4 in the 15th over. The pair took five wickets between them and went for just 51 runs in their 15 overs.

Wickets continued to fall in regular intervals, and with the exception of Ryan Burl who offered resistance by making 79 with 10 fours and four sixes, all the other Zimbabwe batsmen departed for cheap scores. No big partnerships materialised, and Australia took advantage, as offspinner Riley Ayre and medium-pacer Cameron Valente picked up two scalps each to bundle Zimbabwe out in 45 overs. The result left Zimbabwe without a win from their four games.

Vijay Zol's century went in vain as a lower-order collapse from India Under-19s handed South Africa Under-19s a ten-run win.

At 215 for 4 after 43 overs, India were well on course to overhauling South Africa's score of 257, but Zol's dismissal off the first ball of the 44th over from Kagiso Rabada led to a flurry of wickets for South Africa, with the final five batsmen making just 27 runs between them. Rabada eventually finished with 3 for 45 from his 10 overs.

Zol has been in good touch heading into the tournament, hitting back-to-back fifties against Sri Lanka U-19 in August, before smashing 110 for the A team against New Zealand A last month. He produced another compelling batting display on Tuesday, blasting 10 fours and two sixes during his 115-ball 103, and added vital stands of 67, 53 and 67 for the second, third and fourth wickets with Shubham Khajuria, Shreyas Iyer and Ricky Bhui. The four batsmen accounted for 196 of India's 247 runs.

The hosts needed 38 off the last five overs, but the South Africa bowlers held their own and the final two batsmen at the crease, Kuldeep Yadav and Atul Singh, were unable to take India over the line. Medium-pacers Justin Gill and Andile Phehlukwayo picked up two wickets each for the visitors.

South Africa, put in to bat, were earlier propelled by a patient 65 from the opener Clyde Fortuin, who struck eight fours and put up an 83-run opening-wicket stand with Aiden Markram. India fought back with three quick wickets, but Yaseen Valli counterattacked with a 49-ball 64 that included six fours and two sixes, to take South Africa to a competitive total.
