Three wickets each from Dewald Nel and Gordon Goudie helped Scotland bounce back from defeat against Ireland in the opening match of their World Cup qualifying campaign to beat Namibia by 73 runs in Pretoria on Thursday.

Chasing 268 for victory after Neil McCallum (103) and Kyle Coetzer (68) helped the Scots post 267 for six, the Namibians were all out for 194, despite a gallant unbeaten 95 from Gerrie Snyman.

The Africans were never really in the game after Nel (three for 37) claimed a double breakthrough early on.

First he took a skied return catch from Raymond van Schoor (one), before enticing Sarel Burger (two) to play at a seaming delivery that was edged behind to Ryan Watson at first slip.

Namibia were 25 for two at that stage and were in even deeper trouble 30 minutes later, slumping to 48 for five.

Calum MacLeod (two for 38) had LP van der Westhuizen (18) caught at point by Kyle Coetzer, followed by two scalps for Goudie (three for 24), who first had Louis Burger (four) edge behind to wicketkeeper Colin Smith and then bowled Craig Williams (13).

Wickets continued to fall with Nicolaas Scholtz next to go, caught by a diving Nel running in from the deep-square-leg boundary off Moneeb Iqbal for 14.

Bjorn Kotze and Snyman then dug in, sharing a 56 partnership for the seventh wicket, before the former was bowled by Goudie for 20.

Snyman continued to bat with courage, though, raising his half-century off 62 balls as Namibia reached 151 before the wicket of Deon Kotze (eight) fell - run out by Ryan Watson fielding between point and gully.

Ian van Zyl was then trapped leg before wicket by MacLeod for six, before Nel bowled the last man, Louis Klazinga, for a duck.

Earlier, McCallum followed up his 121 against the Irish by slamming another century and was given good support from Coetzer.

The Scots had a difficult start to their innings with the impressive Snyman (two for 61) zipping the ball through.

In his first over he had Gavin Hamilton dropped by wicketkeeper Van Schoor, before hitting the opener in the body in his next, forcing him to retire hurt on two.

Snyman continued to make things happen and made the breakthrough in the seventh over when he had captain Watson excellently snapped up by Sarel Burger at second slip for nine.

Bjorn Kotze was then introduced and he struck with his third delivery when he had new man Navdeep Poonia (four) caught behind by Van Schoor, followed by Sarel Burger cleaning up Smith (nine) to leave the Scots at 48 for three.

But Coetzer and McCallum dug in, with the former raising his 50 in 80 balls, which was followed by the half-century stand in the 30th over.

They then registered the 100 stand in 122 balls but Coetzer was out shortly after when he was excellently caught by Williams at long off off the bowling of Snyman.

McCallum brought up his half-century from 63 balls as Scotland entered the final 10 overs on 156 for four.

He lost his partner Iqbal, bowled by Klazinga (two for 60) for 16, after the pair put on 40 together.

Jan Stander, who finished with 37 off 17, then came in and blasted Snyman for 20 runs in the 47th over, before McCallum brought up his ton in 90 balls, including seven fours and five sixes.

He was bowled by Klazinga in the final over as Scotland posted what eventually proved a match-winning total.
