Colombia became the first side to book a spot in the Copa America Centenario quarter-finals on Tuesday after beating Paraguay in Pasadena, while the United States kept their hopes of advancing alive by thrashing Costa Rica 4-0.
Colombia's 2-1 win put them top of Group A on six points, with the United States on three and the other two teams on one point each.
After losing their opener 2-0 to Colombia, the United States were in clinical form against the Costa Ricans in Chicago and scored three times in the first half through Clint Dempsey, Jermaine Jones and Bobby Wood.
Substitute Graham Zusi added a fourth in the 86th minute to cap the win and improve the hosts' goal difference.
In the second Group A game, played at the Rose Bowl in Pasadena, California, Colombia took a 2-0 lead in the first half but were pushed hard in the second.
Carlos Bacca scored the opener in the 12th minute with a header before James Rodriguez doubled Colombia's lead with a left-foot strike on the half-hour mark.
Paraguay gradually played their way back into the match and hit the woodwork before half-time before forcing David Ospina into a world-class save in the 62nd minute, the Colombia goalkeeper diving full stretch to turn a header around the post.
Paraguay continued to dominate the second half and were rewarded when midfielder Victor Ayala scored with a stunning 30-yard rocket in the 71st minute.
However, they could not force an equaliser and Colombia hung on to take all three points and claim a berth in the next round. Paraguay must now beat the United States on Saturday to have any chance of advancing to the quarters.
