Caribbean representative Dominican Republic ended their Concacaf Women's Gold Cup campaign winless, as they went down 0-3 to Argentina, while Mexico stunned tournament favourites United States 2-0, in the final round of Group A fixtures at Dignity Health Sports Park in Carson, California, on Monday.

The results saw Mexico finishing tops in the group on seven points, with United States second on six, while Argentina improved their chances of being one of the two best third-place teams to progress to the quarterfinals, as they end third on four points. Dominican Republic finished without a point and conceded 16 goals.

Dominican Republic vs Argentina

With two third place spots up for grabs at that point, both Dominican Republic and Argentina started purposefully and with some intensity as they went in search of their first win.  The fact that Argentina held Mexico to a goalless stalemate to start the tournament, while Dominican Republic lost 0-8 to the same opponent, meant the South Americans were a bit more confident, and they put that on display in the early exchanges.

They pushed back their Spanish-speaking Caribbean rivals into a defensive posture and fired a few warning shots from a distance, before they inevitably broke the deadlock in the 30th minute. Midfielder Dalila Ippolito fired home from a one-on-one situation with Dominican Republic's goalkeeper Paloma Pena, after the opponents defence failed to take care of possession.

Argentina doubled their lead in the second half through Celeste Dos Santos's 76th-minute effort, which polished off a tidy one-two combination with Mariana Larroquette.

And the win was capped by Maricel Pereyra in the 90+4, who fired home from just outside the 18-yard area.

United States vs Mexico

The feature contest of the group ended with Mexico securing a historic 2-0 win over four-time World champions United States to take top honours.

It is the first Mexico win against the United States since 2010, a span of 16 matches. The two goals also snap a streak of 33 straight matches in which the United States kept a clean sheet in Concacaf competitions.

Both teams gave as good as they got in end-to-end action, with strikers Sophia Smith of United States and Mexico's Maria Sanchez testing the goalkeepers Esthefanny Barreras and Alyssa Naeher, who both proved equal to the task.

Mexico eventually found the go-ahead goal in the 38th minute when Jaqueline Ovalle capitalized on a defensive error by Becky Sauerbrunn and fired past the hapless Naeher, who was left for dead after advancing off her line.

Karla Nieto went close to doubling the lead on the stroke of half time, but her well-struck shot from just outside the 18-yard box, rattled the crossbar.

United States went in search of the elusive equaliser, but their hunt ended fruitless, as Lindsey Horan fired a freekick over the crossbar in the 56th, while Trinity Rodman's 89th-minute effort went just wide of the upright.

And if that wasn't bad enough, Mayra Pelayo rubbed salt in the United States wounds in the 90+5, when she rifled home a right-footer from outside the box, that lodge in the top right corner, to gift Mexico an historic victory.
