Wales produced a brilliant final quarter to edge Uganda 49-47 and finish top of Pool D with a 100% record at the Netball World Cup in Sydney.
Trish Wilcox’s side advance to a pool containing England, South Africa and holders Australia.
Wales were in front until the third quarter, when Uganda took a 39-35 lead.
But a faultless shooting display in the final period by Chelsea Lewis and Emma Thomas, who hit all 14 of her shots in the game, pushed Wales to victory.
Wales are back in action on Tuesday when they face South Africa at 03:20 BST.
Uganda also qualify as runners-up and in the next round will face New Zealand, Malawi and Jamaica, who beat Scotland 71-24 in Monday’s later game.
2015 Netball World Cup
|Round two of the competition in Sydney starts on Tuesday, when the 16 nations split into four pools of four teams.
|The first two pools are made up of the teams who finished in the top two of their preliminary-round groups, and a round-robin format will decide who progresses to the semi-finals.
|The other two pools will filter into the play-offs for the placing matches.
Wales often found their mid-court passing disrupted by the good coverage of the Uganda players, but wing-attack Bethan Dyke and centre Kyra Jones – who sat out the third quarter – worked tirelessly to feed their shooters.
Captain Suzy Drane and vice-captain Rosie Pretorius needed treatment for leg problems during a hugely competitive match.
Wales – ranked eighth in the world – will hope the pair have suffered no lasting effects as they head into a difficult Pool F against world number one Australia, third-ranked England and South Africa, who are ranked fifth.
