Winger Ignacio Mendy has finished with three tries as Argentina overwhelmed Uruguay 79-5 in the first official rugby Test between them in 18 years.
Play ran his way constantly at the start of the match in Montevideo but left winger Mateo Carreras also got in the action, scoring two tries and creating another for fullback Santiago Cordero.

Los Pumas, who have never lost to Los Teros, eclipsed their previous biggest win, 72-5 in 1998.
After tying the home series with France, new Pumas coach Filipe Contepomi used the match to try several new or returning players, including the Benetton winger Mendy, who was playing his first Test since 2021.
Among the newcomers, back-rower Joaquin Moro debuted in place of Pablo Matera on the blindside flank and marked the occasion with two tries.
"From the first (France) game to the second we improved, and the big challenge for us was to keep improving and I think we did it," said Matera, who came off the bench.
Uruguay were playing only their second match under new coach Rodolfo Ambrosio.
There was some optimism around the team this season after beating Namibia at last year's World Cup and being competitive against France and Italy. But on Saturday, their challenge of Argentina's rugby supremacy in South America faded quickly.
Mendy had his first try in the fifth minute, added his second in the 11th and his incision into the backline in the 27th contributed to a try for centre Jeronimo de la Fuente.
Carreras got his hands on the ball in the 30th, beat thin defence down the left and handed the ball infield for Cordero to score.
De la Fuente provided the last pass for Moro's first try, and fellow back-rower Joaquin Oviedo scored in the 38th in a move in which Mendy handled twice. Carreras' try ended a dominant first half after which Argentina led 44-0.
Mendy needed only three minutes in the second half to complete his hat trick.
Juan Bautista Hontou came off the bench to score Uruguay's first try from slick backline play in the 46th.
Replacement prop Francisco Coria Marchetti also scored on debut when the ball fell to him unexpectedly at a lineout and he found no one between him and the tryline.
Carreras and Moro notched their second tries and Gloucester winger Santiago Carreras came off the bench to score Argentina's final five-pointer in the 77th minute. No.10 Tomas Albornoz finished with nine goals from 13 attempts.
"We didn't expect this result and for sure it's a disappointment," Uruguay captain Andres Vilaseca said.
