Danny Baggish has secured a return to the William Hill World Darts Championship, while Darin Young and Chuck Puleo will represent USA at the BetVictor World Cup of Darts.
The trio secured their places on two of the PDC's biggest stages in the Championship Darts Corporation's four-event American weekend in Indianapolis on October 3-4.
Young and Puleo will resume their pairing in the World Cup in Austria next month, having previously competed together in the 2019 event as they overcame China before losing out to Austria.
The pair held off the challenge of emerging star Danny Lauby over the weekend to secure their World Cup places.
2019 North American Championship winner Baggish, meanwhile, sealed his World Championship return in style by winning three of the CDC's four events over the weekend.
Florida's Baggish defeated Andy Boulton on his World Championship debut last December, before losing out to Nathan Aspinall in round two.
He will join Lauby - the 2019 CDC Continental Cup winner - in representing America in the 2020/21 William Hill World Darts Championship.
Matt Campbell secured the Canadian qualifying place at Alexandra Palace in the CDC's Woodstock weekend on September 26-27, and he will also partner PDC Tour Card Holder Jeff Smith in the World Cup.
