Dillon Pennington made his ICC Under-19 World Cup debut as England defeated Namibia by eight wickets in their opening group match in Queenstown, New Zealand.
The Worcestershire paceman shared the new ball and sent down a total of six overs for 33 runs.
Worcestershire supporters were able to see the potential of Pennington and his team-mates in a match shown live on Sky Sports.
He sent down four overs in his initial spell for 21 runs and returned to bowl a further two in the 34th and 36th overs.
Pennington also picked up a catch at short fine leg after Namibia skipper, wicket-keeper and opener Lohan Louwrens top edged a Will Jacks delivery.
Namibia were restricted to 196-9 in their 50 overs after electing to bat with Middlesex leg spinner Jack Brooks picking up three wickets.
England made short work of their target with skipper Harry Brooks (59 not out) and vice-captain Will Jacks (73 not out) securing victory inside 25 overs via an unbroken stand of 130.
Pennington and England will next be in action at the same venue against Bangladesh on Thursday.
