Hosts Barbados and Trinidad and Tobago both qualified for the 2019 Netball World Cup in Liverpool as each made it six wins out of six at the Americas Qualification Tournament in Bridgetown.
Only two qualification spots are available at the Garfield Sobers Gymnasium and neither country can now be dislodged from the top two of the round-robin tournament.
Both sides will meet each other in the last round of fixtures tomorrow but that game will simply decide who wins the tournament.
Grenada were the only other country in with a chance of gate-crashing the top two but they were beaten 58-43 by Barbados today to end their hopes.
Trinidad and Tobago proved far too strong in their encounter with St Vincent and the Grenadines, winning 80-26.
Other games today saw United States beat St Maarten 51-36.
Canada defeated winless Argentina 66-22.
Today also saw the start of the Asian qualification tournament with 12 teams competing at the event at Singapore's OCBC Arena.
Only nine teams are eligible to win the two places at the World Cup on offer, however, as Japan, Brunei and The Philippines are associate rather than full members of the International Netball Federation.
Countries have been divided up into four groups of three, with those topping the pile heading through into another group to decide the composition of the semi-finals.
Sides finishing second and third will also advance into the second group phase where they will play in classification matches.
Hosts Singapore began today with a 68-19 win over Brunei in Group C.
In Group A, Malaysia beat Japan 88-13 and in Group B, Sri Lanka thrashed Chinese Taipei 137-5.
Group D saw a 71-36 win for Thailand over The Philippines.
Competition continues tomorrow.
