Namibia captain Lohan Louwrens won the toss and elected to bat, putting on an opening stand of 42 with fellow opener Jurgen Linde. However, both opening batsmen were to fall within three overs leaving the side at 46-2.

The underdogs continued to build small partnerships for each wicket, but were unable to build anything substantial, with three consecutive middle-order wickets falling after adding partnerships in the late 20s.

Surrey youngster Jacks smashed an unbeaten 73 from just 56 balls while Brooks added 59 at almost a run a ball as they racked up a combined 130 to see England home in only 24.1 overs.

England now remain in Queenstown to play Bangladesh on Thursday, while Namibia will set their sights on a very winnable game against the Canadian side in Lincoln.
