Leg-spinner Shadab Khan grabs four for nine in five overs as Pakistan beat Afghanistan by 6 wkts
Qualifier Nepal caused the first major upset of the World Cup, shocking New Zealand by 32 runs in a Group D match in Fatullah on Thursday.
Nepal, which won the qualifying event in Malaysia last year to return to the World Cup after missing the previous tournament in 2014, bowled out the Kiwis for 206 after being set a 239-run target.
While captain Raju Rijal top-scored for Nepal with 48, seamer Dipender Airee’s three wickets and off-spinner Prem Tamang’s two helped clinch the dramatic victory.
Dale Phillips scored 41 to make a late victory bid for New Zealand before he was last out to spark joyous celebrations in the Nepalese camp.
"This was a great win for us,” said Rijal. “We fielded brilliantly to effect three run-outs and that turned the match for us."
New Zealand skipper Josh Finnie said his side messed up what should have been a comfortable run-chase.
"We made the target more difficult for ourselves," he said.
"We must now win the next two games against India and Ireland if we are to progress."
Leg-spinner Shadab Khan, seamer Hasan Mohsin shine in Pakistan win
In Group B games, played in Sylhet, Pakistan crushed Afghanistan by six wickets and Sri Lanka overpowered Canada by 196 runs.
Pakistan’s leg-spinner Shadab Khan grabbed four for nine in five overs and seamer Hasan Mohsin took three for 24 as Afghanistan was bundled out for 126 after being sent in to bat.
Tariq Stanikzai scored a fine 53, but eight batsmen failed to reach double-figures against the sustained pressure applied by the Pakistanis.
Pakistan surpassed the modest target in the 32nd over with Zeeshan Malik making 29, Hasan Mohsin an unbeaten 28 and Mohammad Umar 25.
Shadab, playing his first Under-19 World Cup, admitted he was nervous at the start but settled down to return with excellent figures.
"I tried to bowl as straight as possible without trying too many things," he said.
"I am happy with my performance but more importantly we achieved a convincing win. It has given us tremendous confidence and lifted the entire side."
Sri Lanka too strong for Canada
Sri Lanka showed why it is one of the tournament favourites when it rattled up 315 for six after electing to bat against Canada.
Skipper Charith Asalanka led the way with 76 off 69 balls, the in-form Shammu Ashan hit 74 off 61 balls, Kaveen Bandara made 61 and wicketkeeper Vishad de Silva scored 51.
Canada was shot out for 119 in reply with Arslan Khan playing a lone hand with an unbeaten 42. Lahiru Kumara, Thilan Nimesh and Damitha Silva claimed two wickets each.
